 What s New in A-SVS Version 1.4
   Technology Enhancements
   Improved Radio Link and IP Integration SVS integrates IP and Application
   Layer (FTP / HTTP / etc.) performance data with the test mobile, scanner and
   infrastructure-specific call or cell tracing programs already being used for network
   analysis and benchmarking. With this version of SVS, there is no longer a need
   for a separate IP sniffer. Application protocols supported include IP, PPP, TCP,
   UDP, ICMP, MIP, RTP, PAP, CHAP, WAP, FTP and HTTP. IP and PPP
   signaling, events and statistics are supported directly for the following drive test
   vendors:
               Grayson
               WillTech
               Spirent
               Qualcomm, and any derivative of the Qualcomm format that
               supports PPP Tx Frames (Log Code 0x109C) and PPP Rx
               Frames (Log Code 0x109D)
   Improved Grayson File Format Performance           Support for the Grayson
   Invex3G file format has been greatly improved by optimizing the way that SVS
   communicates with Grayson s reader software.

   Data Visualization
   Preconfigured StateForms - A number of preconfigured CDMA StateForms
   enable the user to quickly identify and troubleshoot important network events.
   StateForms Charts In addition to viewing parameter values at selected data
   points, charts can be added to StateForms to view trends in the data over time.
   Events and parameters can be displayed on these charts, and the granularity of
   time can be selected.
   Event Navigator The Event Navigator view in the StateForms allows you to
   view the important voice or data events that occurred during the drive overlaid on
   a bar which shows the calls data in the file colored by serving channel.
   Protocol Stack Browser         The Protocol Stack Browser allows the user to
   quickly browse through messages by examining the header only. Once a
   message of interest is identified in the top pane of the Protocol Stack Browser,
   the details of the message can be examined in the bottom pane.
   Cell Site Configuration The Network Explorer has been updated to ease the
   cell site configuration process. The Auto Import feature is available to

 Getting Started With Analyzer
        Starting Analyzer
        As with any Windows application, you can start Analyzer in several
        ways. When you install Analyzer, a folder is created from the Start
        button that contains a shortcut for Analyzer.

        To use this shortcut to start Analyzer, select Start       Programs
        Actix   Analyzer.



        Note: If you would like to add an Analyzer shortcut      to your
        desktop, right-click on the Analyzer item on the start menu and
        choose Create Shortcut. It will appear on the desktop.

                                                                Analyzer Shortcut

        Configuring Analyzer
        Before you can begin analyzing data, there are a few configuration
        matters to attend to. In order to obtain some geographical reference
        points for your logfiles, you will need to load some MapInfo maps and
        point Analyzer to a valid, applicable cell site database, known in
        Analyzer as a cellrefs file.

        Setting up Maps

        This section shows you how to load MapInfo tabular (.tab) data to
        present data analyses on map backdrops.
           1. Create a new map by selecting View        Display new Map
           2. Click on the Maximize icon to maximize the Map window.

           3. In the Map Window, click on the Layers icon:          .

           5. In the Layer Control dialog, click Add to open the Open Layer
              dialog.
           6. Select or type in the name of a MapInfo Map (*.tab) file, then
              click Open. In class, the map files we will open are
              GAFULTS.tab and GACLYTS.tab. Both files can be found
              within:
                         C:\Program Files\Actix\Analyzer\MapFiles
              MapInfo layers are named according to the geographic
              location of the data (usually abbreviated US state name
              and/or county name), and by the type of data contained in the
              file. The following table lists some of the common
              abbreviations used for MapInfo data types:
                    Suffix       Layer Type
                    Y1           RtHwy010_Top

                    level tables (school districts and elevation
                    contours)
              For example, the MapInfo layer named GAFULTS.TAB
              contains street-level data for Fulton County, Georgia.


           7. You may want to modify the layer properties by selecting the
              layer and choosing the various options within the Layer
              Control Dialog:
              A. Properties     Labels: Use the Label Properties dialog to
                 show, hide, or modify map labels.
                        To turn off labeling (recommended to improve map
                        load time), uncheck the Display within range box.
                        Check boxes also are also available to Allow
                        Overlapped Text and Allow Duplicated Text.
                        The label font can be controlled through the Label
                        Style button.
                        The label position and label offset can be modified
                        at the bottom right corner of the dialog.
                        Select OK to exit the Label Properties dialog.
              B. Properties      Display: Use the Display Properties dialog
                 to control the display features of the map layer.
                        Override the default vector coloring by checking
                        Override Style and modifying the Layer Style.
                        Select OK to exit the Display Properties dialog.

                 buttons to change the ordering of the layers.
                        Moving map layers to the bottom of the layer stack
                        is recommended to provide an uncluttered backdrop
                        for cell site data and logfile parameters.

                        box next to the layer name under the eye icon     .
                        To make a layer selectable, check the box next to
                        the layer name under the arrow icon  . To make a
                        layer writeable, check the box next to the layer
                        name under the pencil icon        .
                        Layers    Remove: Use the Remove button to
                        remove a map layer from the workspace.


           8. After modifying any desired layer properties, close the Layer
              Control dialog with the Close button and changes will take
              effect.




                                                                 Map Toolbar

              interest on the map. Return the cursor to the passive mode
              by clicking on the Select button.
           11. In order to ensure faster loading of maps in future Analyzer
              sessions, load only the MapInfo layers that you need. In most
              cases, street-level data is all that is required for looking at
              optimization data. Too many layers make the map look
              cluttered, and increase the time required for the map to load.

        More Pan and Zoom Options

        The pop-up menu in the Map window offers a variety of convenient
        pan and zoom options.

        Previous View     Right-click in the map and select Zoom

        Map Scale and Coordinates
        By default, the map scale will appear in the lower left corner of the
        map window. In addition, the latitude and longitude coordinates of
        the cursor can be displayed.
               To turn on or off the scale, right-click on the map area and
               click to check or uncheck Show Scale.
               To show or hide the cursor coordinates, right-click on the map
               area and click to check or uncheck Show Lat/Long.


        Loading Cell Site Data
        In order to display cell sites in Analyzer, and integrate cell site data
        with real-time measurements, a formatted cell site database must
        exist containing location and configuration data for each cell site. In
        Analyzer, we refer to this file as the Cellrefs file, although this file
        can have any name.
        Later in the course, we will show you how to format your own data for
        recognition by Analyzer. For now, we will point Analyzer to a pre-
        formatted cellrefs file, and then display the sites on the map.
           1. From the main menu, select Tools        Preferences.
           2. In the Change Preferences dialog, on the File Location line,
              double-click on the name of the current cellrefs file.
           3. In the Open dialog, navigate to the cellrefs file you would like
              to use and select Open. In class the file we will use is called
               Training CDMA Cellrefs.txt which has been installed in the
              following location:
                        C:\Program Files\Actix\Analyzer\Bin\Cellrefs
           4. Click OK to close the Preferences dialog.
           5. A message box will be displayed saying that the new Cellrefs
              file takes effect when a new workspace is loaded. Click OK to
              close the message box. Analyzer loads cells upon opening
              Analyzer or starting a new workspace. From the Main Menu,
              choose File       New Workspace to create a new workspace.
              At this point, there is no need to save the current workspace.
           6. In the new workspace, click View      Display New Map.
               By default the cell sites are now visible.

      Displaying Site Labels
      By default, site and cell labels will be displayed on the map. You can
      leave the labels as they are, modify the way they are displayed, or turn
      them off entirely. The site labels are displayed independently of cell
      labels. This allows you to display of Site Name or Site ID in addition to
      or instead of PN, Azimuth, or Beamwidth.
      In Analyzer, sectors are called cells based on the European GSM
      standards terminology.
      The following instructions specify first site labeling, then cell labeling:
         1.    In the Layer Control dialog box, select the site layer (named
               CDMA_Site-Site_Name)
         2.    Under the Properties heading in the Layer Control dialog,
               press the Labels button.
         3.    The MapInfo-style Label Properties box will appear. Verify
               that each of the following boxes is checked:
                        Show
                        Allow overlapped text (recommended)
                        Hide adjacent duplicate text (optional)
         4.    In the Label Properties box, use the drop down Data Field
               menu to determine the label format to display. Currently, there
               are two formats of labels from which to choose:
                      The Site Name (default) shows only the site name.
                      The Key Field label shows only the site ID.
         5.    If you wish to offset the label from the cell site symbol, use the
               options in the Position box in the Label Properties dialog.
         6.    If you wish to change the font of the labels, use the Label
               Style button in the Properties dialog.
          7.   Select OK to exit the Label Properties dialog.

         The Site Labels have been formatted. Next, format the Cell Labels:
         1. In the Layer Control dialog box, select the cell layer (named
            CDMA_Cell-Beamwidth-PN)
         2. Under the Properties heading in the Layer Control dialog,
            press the Labels button
         3. The MapInfo-style Label Properties box will appear. Verify that

 Data Aggregation (Binning)
        Analyzer aggregates data into groups called bins in order to provide
        a reasonable number of data points from a computing and analysis
        perspective. The aggregation method used to create one bin from
        many data points is dependent on the type of parameter. For
        example, measurement parameters, such as EcIo_1stBest and
        ForwardFER, are binned by averaging each of the component
        measurements into one data point. For network state parameters,
        such as CDMA HandoffState, a bin is given the value of the
        parameter that occurred most often in the bin. Events, such as
        dropped calls and handoffs, are binned by the number of events
        occurring within the component measurements.
        There are four modes for determining how to divide data into bins:
             Time-based binning
             Distance binning
             Message binning
             Location binning

           Time-based binning combines data in the time domain using a
              user-specified duration for the bin. The speed of travel during
              logging will affect how many log files you see in a certain area.
              The diagram below looks at a one-second bin.




           Distance binning combines data into bins corresponding to the
              distance traveled by the test mobile. This mode is commonly
              used for drive test analyses when viewing on a map to ensure
              plot points are evenly spaced.

           Message binning sets the number of messages to average equal
             to 1. Each message is placed into its own bin with the net
             result of no averaging of the data. Message binning should not
             be set to any value other than 1.
           Location binning - analogous to overlaying a spatial grid on top of
              the data with a user-definable granularity. This can be used
              when examining several drive files crossing over the same
              geographic area. This method is often used for SuperStreams.

                             produce one plot point

        Setting the CDMA Configuration Parameters

        CDMA-specific parameters can be changed within the Tools
        Preferences dialog box under General Settings       Decode
        Settings.

        Use the Decode Settings to change the Scanner Ec/Io Threshold
        (dB) for PN Scanner data. Analyzer will display scanner
        measurements at or above this threshold:
           1. Under Decode Settings, double-click on the Scanner Ec/Io
              Threshold (dB) line
           2. Change the threshold from 15 dB to 18 dB. The CDMA
              StateTip, which will be introduced later in the course, will now
              display all measurements at or above 18 dB.
           3. A new workspace must be opened for all Preferences
              settings to take effect.
        A detailed list of all the parameters that are located in the Decode
        Settings dialog box can be found in Appendix A.
        Agilent-specific settings can be found in the Tools       Preferences
        dialog under Agilent MDB and Agilent SD5 . Agilent MDB handset
        and scanner data are used throughout this training course. Make
        sure the following options are set for Agilent MDB files:

        Figure 10 - Expanded Handset Stream Showing Data Groups and Parameters


        Upon loading a CDMA 1x handset file, note that several data groups
        are created. These data groups are common in Analyzer to all CDMA
        handset files, regardless of data collection vendor. Each group will
        appear as long as at least one parameter within that group was
        collected by the device.

        Examining PN Scanner Data

        Due to the nature of the coding scheme in a CDMA system, PN
        scanner data is an invaluable tool for detecting problems in the
        network. Because PNs are reused across a CDMA network with a
        much lower frequency than in an FDMA/TDMA network, each PN
        scan can be directly linked to a particular site or sector in the
        network.
        The Phone & Scan 1.mdb file already opened in the workspace
        contains PN Scanner data as well as handset data. The PN Scanner
        stream is the one that is labelled as the PCS Receiver, in this case
        HP E6450B (PCS Receiver) 1947.500 MHz (1).
        Expand the scanner stream to reveal the contents of the data stream:

             Figure 11 - PN Scanner Stream Expanded to Show Its Contents


        Note that under the Pilot Measurements data group, several groups
        have been created to help you easily drill down into the data. For
        each scanner stream, the following measurements are available:
              EcIo_for_PN     Ec/Io measurements for each PN scanned
              EcIo_for_Nth_Best_Pilot Ec/Io measurements ranked from
              the strongest to the weakest, for the top N best pilots collected
              PN_for_Nth_Best_Pilot The PNs, ranked from strongest to
              weakest Ec/Io, for the top N best pilots collected
              Ec_for_Nth_Best_Pilot      Ec measurements, ranked from
              strongest to weakest Ec, for the top N best pilots collected

        Expand the Multipath Measurements group. Note that the
        measurements are divided into Ec/Io measurements and Delay
        measurements.


        The measurements contained in the Ec/Io data group are:
              EcIo_Max     The instantaneous maximum Ec/Io
              EcIo_Spread_for_PN The difference between the Ec/Io of
              the first arriving multipath component and the last arriving
              multipath component for each PN scanned
              Multipath_1_EcIo_for_PN         Ec/Io measurement of the first
              multipath for a given PN above a user-defined threshold. To
              set this threshold, go to Tools        Preferences    Decode
              Settings. The EcIo Threshold for Delay (dB) parameter
              defines the threshold for this multipath measurement.
              PN_at_EcIo_Max       The PN providing at the maximum Ec/Io


        The measurements contained in the Delay data group are:
              Delay_1_Max     The maximum delay in chips for the first
              multipath component
              Delay_Spread_for_PN          The delay difference (in chips)
              between the first and last arriving multipath measurements for
              each PN scanned
              Max_Delay_Spread The maximum delay spread (in chips)
              for any PN at a given instant
              Multipath_1_Delay_for_PN        Delay measurements for the
              earliest arriving multipath component for each PN scanned
              above a user-defined threshold. To set this threshold, go to
              Tools       Preferences       Decode Settings. The EcIo
              Threshold for Delay (dB) parameter defines the threshold for
              this multipath measurement.
              PN_at_Delay_1_Max The PN           for   the   maximum   delay
              component of the first multipath

        Searching for Attributes
        With such a high number of attributes (or parameters) available for analysis,
        it can become quite tedious to locate the exact attribute that one might
        need. The Search for Attributes feature allows a user to search the
        parameter trees of all open data streams within the Workspace Explorer.
        The results of the search will be displayed in the Search Results tab of the
        Workspace Explorer.

        1. From the main toolbar, select Tools       Find Attribute. The search
           panel will open as part of the Workspace Explorer window.
        2. In the Find What field, type some text that is part of the required
           attribute.
        3. Select the Stream in which to search for the attribute. The default is set
           to <All Streams>.
        4. Select either of the Settings options   if desired.
        5. Select the Direction in which to search.
        6. Click Find Next or Find All.

        When finished, click Done. The search panel will close. However, all of the
        results will remain visible in the Search Results tab.


        The Favorites Group
        Having access to all of the parameters within a logfile in the
        Workspace is sometimes not necessary and it can make finding key
        parameters more difficult. Analyzer allows for the identification of a
        subset of parameters that need to be accessed regularly by placing
        them in a Favorites Group. This group can be viewed by clicking on
        the Favorites tab in the Workspace. Try setting the following favorites
        for CDMA 1x handset parameters based on handset stream of
        CDMA 1x Data Willtech.0401:
           1. In the Workspace, click to select the Pilot Measurements
              EcIo_Combined parameter, then right-click on it and choose
              Add to Favorites from the pop-up menu.
           2. Under Downlink Measurements, find ForwardFER and add
              it to Favorites.
           3. Under Event Data, find CallDropped (from the Call Events
              group) and HandoffOK (from the Handoff Events group) and
              add them to Favorites.

           4. Under         RLP            Statistics,    find
              RLP_Rx_Throughput_Instantaneous             and
              RLP_Tx_Throughput_Instantaneous and add them to
              Favorites.
           5. In the Workspace, click on the Favorites tab. A tree view of
              the items that were added is displayed. You can easily move
              between All and Favorites as necessary.
              The parameters that you define as favorites will be available
              on the Favorites tab for any data file open in the workspace
              that contains those parameters, as well as for any new files
              opened that contain the specified parameters.




              Figure 12 - Workspace Showing the Favorites Parameters Displayed


           6. To remove a parameter from favorites, select the parameter.
              Right-click on it and choose Remove Favorite.

        Sharing Favorites

        Favorites can be shared among users. Favorites are saved in the
        Favorites.dat file located in the C:\ProgramFiles\Actix\
        Analyzer\Bin\XMLFiles directory.
        To share Favorites with another user, copy the Favorites.dat file to
        the same directory on the desired machine. The user of that
        machine will then have access to those Favorites each time Analyzer
        is launched.

 Viewing Data in Analyzer
        In Analyzer, data can be viewed in a variety of ways to facilitate easy
        analysis. You can plot parameters on maps and display them on
        charts, tables, and in workbooks.

        Viewing Data on Maps
        There are two options for viewing data on maps:
              To view any parameter on a new map: Right-click on the
              parameter of interest in the Workspace Browser and select
              Display on Map.
              To view a parameter on a map already open in the
              workspace: Click and drag the parameter of interest onto a
              map already open in the workspace.

        Modifying Legend Ranges
        From the handset stream of the Phone and Scan 1.mdb file,
        display EcIo_1stBest on a map and try the following:
           1. In the legend, right-click on EcIo_1stBest and select Modify
              Ranges to change the ranges displayed.




                             Figure 13 - Modify Ranges Dialog Box

                                                                                     Introd uc tion to A-SVS for CDMA
           2. Remove any unwanted ranges by highlighting the range and
              selecting Remove. Ranges must be removed one at a time.
              Analyzer will not allow the deletion of the last two remaining
              ranges.
           3. Enter the maximum and minimum value for each range and
              click Update to modify an existing range, or Add to add a new
              range. Use the Below and Above buttons to specify edge
              ranges. The recommended approach to modifying legend
              ranges is to start with the minimum value ranges and work
              your way toward the maximum.
           4. Within the Modify Ranges dialog, you can change the color
              assigned to each of your new ranges. With the range
              highlighted, click on the Selected Button in the Set Colors
              section. To set all of the ranges to default colors, click on the
              Default button in the Set Colors section.
           5. Press Close to close the Modify Ranges dialog and return to
              the workspace. All range and color settings are automatically
              saved with the Modify Ranges dialog is closed.
           Note: Use the Cancel button to back out of any changes you do
           not want to keep.

        More Range Display Options
        Right-click on the stream in the legend for more legend options:
              Select Attribute Style to change the color, size and shape of
              the data trail. These parameters affect all data points for this
              parameter, regardless of value.
              Style Setting lets you decide whether to indicate a
              parameter s value range changes by color, size, or shape.
              The Set Legend To menu item allows you to maintain multiple
              legend configurations for a single parameter. The default
              legend settings will always be used upon entering a new
              Analyzer workspace. To maximize the utility of this feature,
              give each legend configuration for a parameter a unique name
              and set the preferred configuration to be the default.
              The Copy Legend to Clipboard and Export to File options
              let you create an image of the legend for use in other
              Windows programs.
              Change the style of an individual range without re-entering the
              Modify Ranges dialog by right-clicking on the range and
              selecting Selected Range s Style.

               Changes to legend settings are automatically saved by
               Analyzer. This information is saved in XML files, one for each
               parameter. The files are saved in the C:\Program
               Files\Actix\Analyzer\Bin\FormatGroups\UserSettings
               folder. After legends have been modified and saved as
               desired on one computer, you can transfer these files to the
               same location on another computer to share legend settings
               between users.

        The Map Offset Tool
        Offsetting of a data trail on the map may be achieved by manually
        offsetting the data on the map, or by specifying a numeric distance to
        offset the trail in the x and y directions.
        To use the Offset Tool to offset a trail:
           1. View ForwardFER on the map in addition to EcIo_1stBest by
              dragging ForwardFER onto the existing map.
           2. In the Map Layers dialog, highlight the layer you wish to offset
              and then select Offset   Offset Tool.
           3. Move the Offset Tool cursor to determine how much to offset
               the trails. Click the mouse once to accept the modified
               position.

              other parameters.
           7. In addition to selecting single points, you can select more than
              one point. Click on the Area Select button on the map
              toolbar. Use the Select Box tool to select a group of data
              points on the map. The resulting lines to serving and neighbor
              cells for multiple data points may be useful in determining
              whether calls made in an area are being served by the
              appropriate cells.

        The Direction Button
        The Direction button allows the user to display directional arrows on any
        drive-test map. These arrows indicate the direction of the drive test vehicle
        during collection. The Direction button is located on the Map Toolbar.




                                                                  Direction button

        Region Filtering
        The Region Filter can be used to filter data displayed on maps. It can be
        very helpful when trying to isolate data in one geographical area.

        1. From the Map Toolbar, click the Region Filter button. Three additional
           options will now appear on the map toolbar; including a Polygon
           drawing tool. The cursor will now appear as a cross-hair on the map.
        2. Draw the polygon over a certain map area by clicking on a series of
           points. The first click on the map starts the polygon. Drag the cursor to
           each corner of the desired region to filter and click the mouse once. To
           finish drawing the polygon, double-click near the starting point to
           establish a line between the last point and the first point.
        3. Draw any other polygons, as needed.
        4. To filter data, click the down-arrow next to Filter and select either
           Include or Exclude. Include is the default filter. [Note: Any additional
           attributes that are dragged onto a map using regional filtering will also be
           filtered].

        Printing Maps

        A-RLAS-ID features five different ways to obtain printable map outputs:
              Print using Quick Print
              Print using Map Layout Designer
              Copy to Clipboard
              Export Map to a different file format
              Export individual map layers to MapInfo


        The recommended method is the Quick Print. The Quick Print option
        bypasses the Map Layout Designer and prints the map with a legend in a
        fixed position.
        To print a map using the Quick Print option:
           1. Display data on a map in the workspace.
           2. Select the Print button from the map toolbar.
           3. Select the paper source, page orientation, and margin sizes.
           4. Use the Options button in the lower left hand corner of the Print
              Setup dialog to adjust map size, content, legend visibility, and scale.
           5. In the Print Setup dialog, select OK to print the map.
        The Map Layout Designer may be used to arrange the map and legend on
        the page, add a title, and preview the output. To print a map using the Map
        Layout Designer:
           1. Open a map with data in the workspace.
           2. Select the Layout button from the toolbar.
           3. Choose the page layout for the map and select OK to bring
              up the Map Layout Designer.
           4. Double-click on the Label box to change the title of the map.
           5. Move the label box and the map so that they are not
              overlapping. Resize the text box as necessary. With the Label
              Box selected, choose Properties from the Toolbar to change
              the label font.
           6. Move the legend so that it is not overlapping the map trail.
              Resize the legend as necessary.

           7. Select Print Preview from the Toolbar to determine what the
              printed page will look like. Close Print Preview to make any
              modifications necessary.
           8. Select Print to print the map.
        You can also print a map by copying it to the clipboard.
           1. Right-click on the map to be copied and select Copy to
              Clipboard.

           2. Paste the map into another application and use that
              application s print function to print the map.
        A fourth option is to convert the map to a different file format and use
        a compatible program to print the output file. Analyzer supports the
        exporting of maps to the following formats: BMP, JPG, WMF, PNG,
        TIF, GIF, and PSD.
            1. Right-click on the map and choose Export Map.
            2. Select the desired file format.
        Finally, a fifth option is to export individual map layer(s) directly into
        MapInfo. To do this:
           a. From the map view, open the Layer Control dialog box.
           b. Select Export.
           c. Choose the layers to be exported. Browse to the appropriate
              destination folder.
           d. Click OK.

 Viewing Data on Charts
        Analyzer can create a variety of charts for the analysis and
        inspection of data.
        There are two ways to view data on charts:
           1. To view any parameter on a new chart: Right-click on the
              parameter of interest in the Workspace Browser and select
              Display on Chart.
           2. To view a parameter on a chart already open in the
              workspace: Click and drag the parameter of interest onto a
              chart already open in the workspace.

        To demonstrate some of the chart capabilities in Analyzer, we will
        create a Time Series chart containing wireless data parameters.
           1. In the CDMA 1x Data - Willtech file in the Workspace,
              expand RLP Statistics Receive Information and select
              RLP_Rx_Throughput_Instantaneous.
           2. Right-click on RLP_Rx_Throughput_Instantaneous and
              choose Display on Chart from the pop-up menu. Notice that
              a chart appears with a throughput value at each data point.

           3. Click on the Histogram button            to view the data as a
              distribution. The ranges that appear are the same ranges that
              were set for this parameter on the map legend.

           4. Click on the Series button         to return the chart to a time
              series chart.
           5. You may wish to examine an area with particularly high or low
              throughput in detail. To zoom in on a section of the chart, click
              and drag a rectangle, moving from upper left to lower right. To
              return to the previous zoomed view, click and drag a rectangle
              moving from lower right to upper left.
           6. Drag and drop ForwardFER onto the chart.
           7. Drag and drop RLP_Tx_Throughput_Instantaneous (from
              RLP Statistics     Transmit Information) on to the chart. Your
              chart should look like the figure below.

                             and ForwardFER displayed on a chart

              Note that throughput and FER are measured in different units,
              so they appear on separate axes.

           8. Drag and drop the Anchor Transfer event (from the Event
              Data    Data Events group) onto this chart. The events will
              appear on the chart as vertical lines.

           Anchor Transfer is the process used to handle mobility of the
           supplemental channel during a data call on a CDMA 1x network.
           The anchor is the site and sector supporting the forward
           supplemental channel during a CDMA 1x call. Anchor transfer is
           the term given to the handoff of the anchor from one sector to
           another.

        Modifying Chart Properties
           1. Many chart properties can be customized through the
              Properties dialog. Right-click on the chart and choose Chart
              Properties from the menu.
           2. Reposition the Properties Dialog so that you can see the
              chart with the dialog open. As you change the properties of
              the chart, the chart is automatically updated.
           3. On the Chart Series page, click the Title button to change the
              title of one of the series.
           4. Still on the Chart Series page, use the up and down arrows to
              change the order in which the parameters are plotted. This
              also affects their position in the legend.
           5. On the Chart Axis page, redefine the style for the axis, labels,
              and ticks.
           6. On the Chart Legend page, modify the fonts and colors.
           7. Create a three-dimensional chart using the options on the
              Chart 3D page.
           8. Click Close to close the Properties dialog when you are
              satisfied with the formatting you have done.
           9. Click on the Copy icon to place a copy of your chart on the
              clipboard.
           10. In Word or PowerPoint, click Edit        Paste to paste your
               chart into that application.
           11. In Analyzer, with the chart still open, create a map displaying
               the same data. Make sure that the Select tool is activated on
               the map. Click to select data on either the map or the chart
               and notice that the views are synchronized.

 Viewing Data in Tables

        Tables provide a quick view of numeric data for a selected
        parameter. You can look at statistics, such as mean, minimum, and
        maximum, histogram distribution information, or the time series data
        for the parameter displayed on a spreadsheet. Tables can be
        synchronized with maps to provide an integrated view of network
        data. A trouble area that is identified quickly on a map using visual
        inspection can then be examined more closely on a table by looking
        at exact numerical values of key parameters.
        There are two ways to view data on tables:
           1. To view any parameter on a new table: Right-click on the
              parameter of interest in the Workspace Browser and select
              Display on Table.
           2. To view a parameter on a table already open in the
              workspace: Click and drag the parameter of interest onto a
              table already open in the workspace.

        To demonstrate the functionality of the Analyzer table in network
        optimization applications, we will create a new table containing some
        parameters related to wireless data network analysis.
           1. Display RLP_Rx_Throughput_Instantaneous from the handset
              stream of CDMA 1x Data Willtech.0401 on a table. To do
              this, select RLP Statistics    Receive Information
              RLP_Rx_Throughput_Instantaneous, then right-click and
              select Display on Table.

           2. Drag App_Throughput_DL (from the Data Testing
              Application Measurements group) onto the same table to
              view the values side-by-side. Note that while RLP throughput
              provides the data rate over the air interface, application
              throughput provides the data rate experienced by the end
              user.
           3. Click on the Histogram tab and notice the ranges and
              counts. The histogram ranges correspond to the map legend
              ranges set for the last parameter displayed on the table. Use
              the drop-down list at the bottom to switch between histogram
              values for the different parameters.
           4. Click on the Statistics tab and notice the automatically
              calculated statistics for all parameters displayed on the table.
           5. Click on the Series tab to return to that view. Then drag the
              ForwardFER parameter onto the same table.
           6. Display ForwardFER on a new map in the workspace. Make
              sure that the Select tool is activated on the map.
           7. Tile the table and the map in the workspace by selecting
              Window      Tile Horizontally from the main menu.
           8. With the table and map visible in the workspace, select a point
              on the map where FER is high. Notice that the table
              synchronizes to the same point, and that the throughput and
              FER values are now visible for the time before and after the
              instance of poor RF quality. How were RLP and application
              throughput affected by the poor radio conditions?
           9. Open another CDMA 1x handset file in the current workspace.
              Use the stream selection box to look at new handset data in
              the same table configuration without having to repeat the work
              you did to set up the original table.

  Viewing Data in the Message Browser
        Analyzer provides the Message Browser to allow you to analyze the
        messaging reported by the logging device. The browser also includes
        events derived from the Layer 3 messaging and searching and
        filtering operations on the data. The Message Browser can play an
        integral part in a problem-area investigation when it is used in
        conjunction with the Analyzer map and table.
        To open the Message Browser right-click on the handset stream
        under the CDMA 1x Data - Willtech file and choose Display
        Message Browser from the pop-up menu.




                    Figure 20 - Messaging Displayed in the Message Browser


           1. Click on an event in the Event Panel. Watch as the
              Messaging Window synchronizes to display the messaging
              information corresponding to the event you selected. This
              allows a quick view of the specific messaging associated with
              a particular event.
                                                                                                                          Formatted: Bullets and
                                                                                                                          Numbering

           2. The search function can be used to locate a particular
              parameter in the messaging, even if the message name is
              unknown. In the Search box, type SOFT_SLOPE , then click
               the Find Next button            to find the next occurrence of this
               text string in the file. Continue the search by clicking the Find
               Next icon to find each subsequent occurrence of the string.
               SOFT_SLOPE and ADD_INTERCEPT are new CDMA 1x
               parameters designed to increase handoff efficiency.
           3. Right-click on the message area and choose Properties from
              the pop-up menu. In the Properties dialog, click on the
              Message Format tab and modify the Font for the Message
              Browser.
           4. On the Message Filtering Tab of the Properties Dialog,
              uncheck All Message Types and check Reverse Link
              Messages and Forward Link Messages to show only
              messaging collected while the handset was in call mode. The
              message filtering capability is useful when investigating
              specific events, and only the messages associated with those
              events are of interest.
           5. Select a section of text in the Message Browser and click
              on the Copy icon. Open Microsoft Word and click Edit
              Paste to paste the text into the current document.
        One type of analysis where the Message Browser comes in handy is
        the investigation of neighbor list warnings. Most file formats contain a
        NeighborListWarning event that is triggered when the Pilot Strength
        Measurement Message (sent on the reverse link) includes a strong
        measurement of a PN that was not included in the latest Neighbor
        Update list from the base station.
        To perform a basic analysis of missing neighbors using the map and
        the message browser:

 Viewing Data on Workbooks
        In some cases, the Analyzer Table may not provide enough flexibility
        for viewing data. Analyzer s Workbook feature provides a more
        flexible method for detailed analysis of trouble areas. This format
        allows data to be searched, sorted, filtered, formatted, and printed
        through Microsoft Excel.

         There are two ways to view data on workbooks:
         1. To view any parameter on a new workbook: Right-click on
            the parameter of interest in the Workspace Browser and select
            Display on Workbook.
         2. To view a parameter on a workbook that has already been
            opened: Right-click on the parameter of interest in the
            Workspace Browser and select Display on Workbook (active).

        View the EcIo_Combined parameter from the Willtech Kyocera 3G
        handset stream on a workbook:

           1. Select Pilot Measurements      EcIo_Combined, then right-
              click and select Display on Workbook.
              Notice the series data is displayed in Excel with time, latitude,
              and longitude

  The Replay Tool

         The Replay Tool allows you to sequentially view data points in the
         files you are analyzing. Resembling the controls of a VCR, you can
         use the Replay Tool to move forward or backward, automatically or
         manually advancing through the data.
         You can move through data displayed on a Map, Chart, Table or
         Message Browser. The stream selection box allows you to choose
         which stream to replay. It will display all open logfiles, whether or not
         you have a parameter from the stream displayed.
             1. Display Forward FER from Phone & Scan 1.mdb on a map,
                 then drag the dropped call onto the same map.
             2. Display the dropped call, EcIo_1stBest, Forward FER, Mobile
                 Rx Power and Mobile Tx Power on a table.
             3. Use the Window menu to tile the map and table horizontally.
             4. To access the replay tool, select Tools      Display Replay.

        Docking the Replay Tool

        You may find it more convenient to position the Replay Tool under
        the Workspace Browser. The procedure for doing this is called
        docking.
              1. Click on the left-most of the four buttons at the upper right-
                 hand side of the Replay Tool          . If there are only three
                 buttons, minimize and then restore the Replay Tool to
                 make the fourth button appear.
              2. The Replay Tool will now show up along the right side of
                 the Workspace Browser. To move it under the Workspace
                 Browser, click on the thin gray bar at the top of the Replay
                 Tool and drag it to the far left side of your screen.

 Viewing Data on Stateforms

   Actix Stateforms allow you to view multiple performance metrics simultaneously.
   Used in conjunction with the replay tool, maps, tables, and charts, you can
   quickly ascertain the values of several optimization parameters for problem
   identification.

   Using Preconfigured StateForms

   A number of preconfigured CDMA StateForms enable the user to quickly identify
   and troubleshoot important network events. The preconfigured forms available
   for CDMA drive test data are:

              CDMA Handoff Event Navigator
              CDMA Handset PPP Event Navigator
              CDMA Handset Summary Information
              CDMA RLP Statistics
              CDMA Radio Link Summary
              CDMA Voice Event Navigator

         workspace and choose Display Form       CDMA Radio Link Summary.
         Forms can also be selected from the View   Forms option on the main
         menu.
      2. In general, when selecting a form, make sure that the form that you have
         selected applies to the type of data you want to analyze. For example, do
         not select the CDMA RLP Statistics form for a 2G voice logfile.
      3. If the Stream Selector is not visible, right-click on the form and select
         Stream Selector. The Stream Selector drop-down will appear. Use the
         drop-down list to select the stream you wish to view data for. If you are
         not seeing information in the forms, verify that the right data stream is
         selected.

         To dock a form at the bottom of the workspace, bring up the form and use
         the docking button (to the left of the minimize button) to dock it next the
         Workspace Browser. Then, making sure that the right border of the form
         does not stretch past the midpoint of the entire Analyzer viewing platform,
         drag the thin gray line of the form to the bottom right side of the screen so
         that it is completely on the left half of the viewing platform. Once docked
         like in the view above, you can adjust the top border to allow for more
         viewing space in the platform.

         Preconfigured forms can be edited to meet your individual analysis needs.
         The following sections describe the modification of existing forms, and the
         creation of new forms from scratch using the Stateforms Editor.

              directory and open the file called cdma handset.axl.

           2. Once loaded, make sure a stream is selected in the
              StateForms stream selection box. The selected stream must
              correspond to data currently displayed on another Analyzer
              view (map, chart, table or message browser).

              Note: If the stream selection box is not visible, right-click on
              the stateform box and select Stream Selector. The stream
              selection box will appear.

           3. Select any point on a map, chart, or table and notice that the
              contents of the form will update to reflect the state of the
              network at the point you selected.

              window is showing the same stream that you are trying to
              synch with.

      Modifying an Existing StateForms File

      You can use an existing StateForms file as it is, or you can make
      modifications to it. Suppose the CDMA handset file has almost
      everything you would like to see, but that you are also interested in the
      handoff state. To add handoff state to the StateForms display:

         1. If you do not already have the StateForms file displayed, click
            Tools     Display StateForms. Click Open File and choose the
            CDMA handset file.

         2. Click on the Toggle Design Mode button     on the StateForms tool
            bar.
         3. The StateForms window now shows the design view:

 Analysis of Reverse Link Data
        Reverse link data is as important as forward link data to the overall
        health of a wireless network. Because reverse link data is collected
        at the base station, without the benefit of associated GPS data, it is
        not possible to view reverse link parameters such as EbNo and
        Reverse FER on a map.
        Analyzer supports CDMA call trace data from most major base
        station equipment vendors. Call trace data by itself may be displayed
        on an Analyzer table, chart, workbook, or message browser. When
        merged with drive test data collected at the same time as the call
        trace, GPS coordinates contained in the drive test file are associated
        to data points from the call trace. This procedure allows the display
        of reverse link data on a map, and allows the engineer to obtain a
        picture of the reverse link performance of the network.
        In this section, you will look for reverse link problems on the sample
        network using call trace and drive test data.

        Exploring Call Trace Data
        Call trace data may be opened in Analyzer using the same method
        as opening drive test files. Simply use the Open Logfile button and
        browse to find the files of interest.
        Load the following call trace files into the Analyzer workspace. The
        logfiles     can       be       found      in    the     C:\Program
        Files\Actix\Analyzer\DataFiles folder.
                Lucent Call Trace 1.rft
                Lucent Call Trace 2.rft
        Expand the Lucent Call Trace 1 data file and explore the contents.
        Display a parameter on a table. Notice that the file includes uplink
        parameter values, but does not contain location data for each
        parameter.
        Display the parameter ReverseFER from the Uplink Measurements
        group on a chart. Though it is easy to see when the areas of poor
        reverse FER occurred, there is no way to know where in the network
        these areas are located.

                                                                                      Introd uc tion to A-SVS for CDMA
 SuperStreaming Call Trace and Drive Test Data
        Analyzer allows you to synchronize data from the different data
        sources it supports. This functionality supports a collection method
        where drive test and switch data are collected simultaneously on a
        cluster of cells of interest. It aligns the information in the files based
        on a parameter that was collected by both the drive test and switch
        trace devices. This allows you to plot reverse link information on a
        map, or to plot the difference between reverse and forward
        parameters on a map. The process is called SuperStreaming.
        In this example, a parameter common to the drive test and call trace
        files is specified in order to merge the files. Files may also be merged
        based on time, as long as the base station and drive test equipment
        times are synchronized.
           1. Load the drive test and the switch data files from the CD into
              the Workspace:
                    Drive test: MDM_File_2.mdm
                    Call trace: Lucent Call Trace 2.rft
           2. Select Tools      Create SuperStream.
           3. Change the name of the SuperStream from the default of
              SuperStream001 to Forward and Reverse Data.
           4. In the SuperStreaming dialog, check the MDM_File_2 (drive
              test) and Lucent Call Trace 2 (switch file) streams.
           5. Click the Settings button to display the Merge Method
              options.
           6. Select Correlated Parameters as the merge method.
           7. Highlight the MDM_File_2.mdm stream. Use the attribute
              chooser next to Correlated Parameters to select
              PN_Primary (from CDMA       Pilot Measurements group) as
              the correlating parameter for the MDM file. The attribute
               chooser is the button with the right-arrow icon          . Used
               throughout Analyzer, an attribute chooser allows you to select
               the Analyzer parameter of interest without the risk of mistyping
               the parameter name.
           8. Highlight the Lucent Call Trace 2.rft stream. Use the attribute
              chooser to select CellPN_Primary from CDMA             Uplink
              Measurements group.
           9. Click OK to create the SuperStream.

                                                                                   Introd uc tion to A-SVS for CDMA
        Note: In the SuperStreaming dialog box, the parameter that you
        associate with a stream of one type (i.e. .MDM, .RFT) will appear in
        the Attribute column for all streams of that type. However, only
        streams with check marks will be merged into the resulting
        SuperStream.
        When Analyzer has finished creating the SuperStream, it will appear
        in the Workspace:                     . You can perform analyses on
        the SuperStream using the map, chart, message browser, workbook,
        and table features discussed earlier.

        Display ReverseFER from the Uplink Measurements group of the
        newly created SuperStream on the map. Notice how easy it is to
        locate areas containing poor reverse link quality! These trouble spots
        are caused by the phone s inability to communicate back to the base
        station, and may be attributed to a mobile failing to increase its
        transmit power when required or to excessive path loss between the
        phone and the base station.

                                                                                   Introd uc tion to A-SVS for CDMA
 Merging Multiple Drive Files in the Workspace
        Analyzer s SuperStream feature may be used to merge multiple files
        collected on the same link (i.e. drive test or call trace).
        SuperStreaming multiple drive test files is desirable when you require
        one-click functionality for displaying the same parameter from
        multiple streams on any Analyzer view, or when aggregate statistics
        on multiple drives are required. SuperStreaming creates a pointer to
        files already open in the workspace and does not create any new
        files. SuperStreams may be saved in workspaces, as long as all
        component files are saved in the same workspace.

        To create a SuperStream containing several drive test files:

           1. Ensure that the following files are loaded in the Analyzer
              workspace:
                  MDM File 1.mdm
                  MDM File 2.mdm
                  MDM File 3.mdm
           2. Select Tools     Create SuperStream.
           3. Name the SuperStream Merged Handset Data.
           4. In the SuperStreaming dialog, check the MDM File 1, MDM
              File 2, and MDM File 3 streams.
           5. Use Timestamps is the default Merge Method. Click OK in
              the SuperStreaming dialog to create the SuperStream
              merged using timestamps.
        When Analyzer has finished creating the SuperStream, it will appear
        in the Workspace:                   . You can perform analyses on
        the SuperStream using the map, chart, message browser, and query
        features discussed earlier.

                                                                                            Introd uc tion to A-SVS for CDMA
 The Network Image
 Frequently, optimization engineers are asked to provide a complete network
 overview for management, customer service, and planning purposes. A complete
 network drive may consist of a large number of data files from different sources,
 that when combined include a very large amount of data. All of the parameters,
 messaging, and other information available from a logfile may be helpful when
 performing an in-depth analysis, but when you are interested only in general
 information about the state of your network, this information may not be worth the
 time required to load and manipulate it.
 Actix Analyzer allows you to create a composite database consisting of multiple
 drives that is much smaller than the sum of the individual drive files. This is
 accomplished in Analyzer using the Network Image feature. Network Images
 extract the most commonly used network parameters and store them in an
 external file (*.dat). This is useful when you are performing a system-wide analysis
 or benchmarking activity. Because only key parameters are saved into the Network
 Image file, this file is much smaller than the sum of its component files.
 A Network Image populated with data is saved as a separate, smaller file from the
 original logfile. The original logfile is not altered in the creation of a Network Image
 repository.
 The data contained in a Network Image file differs from normal logfiles, in that the
 image file contains only the parameters specified and is binned according to the
 image template. Some pre-configured Network Image templates are packaged
 with the Actix software. It is also possible to create custom Network Image
 templates within the Analyzer workspace.
 This document describes the use of pre-configured templates and the creation of
 custom Network Image templates.

      Use a Pre-Configured Template to Create a New Network
      Image
      Assume you were asked to combine several logfiles representing a day s
      worth of driving by three different engineers. We will create a Network Image
      to consolidate the data into one reasonably sized file:
          1. Create a Network Image by selecting Network Image                    Create
             Network Image from the main Analyzer menu.
          2. For the name, enter Cluster Level Data .
          3. Select the CDMA       Handset     Time Binned (5 Seconds)
             pre-configured template, and then click OK. This will create a
             Network Image of the data sets that are binned every 5
             seconds.

         4. In the Save dialog, save the file in a convenient location.
             Your workspace will update after creating the Network Image. Browse
             the workspace and investigate the new Network Image called Cluster
             Level Data. This Network Image is currently an empty shell that will be
             populated with data extracted from logfiles.

     Batch Load Files into the Network Image
     The Network Image that you just created is nothing more than an empty
     directory structure. You must now add data from log files into this structure.
     Files do not need to be open in the workspace in order to be added to the
     Network Image.
     1. To load files into the Network Image, right-click on the Cluster Level Data
        Network Image in the workspace and select Batch Load Files.
     2. In the resulting dialog, browse and select several CDMA handset files
        (Note: Unlike with the Superstream, these files DO NOT need to be open in
        the workspace).
     3. Click Open to begin processing the files.
     4. A Load Results report, like the one shown below, will appear once
        processing is complete. Select OK to close the report.

      Display Data for the Entire Network

      Many logfiles contain data for more than one device. Network Image
      templates, such as the Time Binned template used in this example, can
      accommodate multiple data streams collected under a single logfile.
      1. Expand the Cluster Level Data Network Image. Notice that key
         optimization parameters in the Time Series, Downlink Measurements,
         Dedicated Radio Link and Event Data groups are included in the
         Network Image.
      2. Using standard Analyzer actions, display some parameters on charts,
         maps, and tables.
      Note that you can process scanner and handset data into a single Network
      Image or create a separate Network Image for scanner data, using the
      templates supplied with your Analyzer installation.

      Start a New Day         Attaching a Network Image

      Saving multiple files into one Network Image will allow a significantly faster
      load time than when loading each file individually. Demonstrate the faster
      load time by starting a new Workspace and attaching the Network Image.

      1. Create a new Workspace by selecting File           New Workspace from the
         main menu.
      2. Attach the previously created Network Image by selecting Network Image
            Attach Network Image.
      3. In the resulting dialog, browse and select the Cluster Level Data Network
         Image.
      4. Select Open to attach to the Network Image. The Workspace will update
         to reflect the change. Notice how quickly the Network Image attaches!
      5. Expand the Network Image. Display some parameters on Charts, Maps,
         and Tables.
      Key optimization parameters from multiple files have been combined into a
      single, smaller file that loads into Analyzer much faster than the original files.

                                                                                      Introd uc tion to A-SVS for CDMA
         Step 2     Choose Your Devices:
                  o You may want to process different data streams in different
                    ways. For example, you may want to extract different attributes
                    for handset and scanner data captured in the same logfile. You
                    can define a meaningful Device Name and specify a Filter to
                    uniquely identify each device within a logfile. When populating
                    the Network Image, only data streams with names containing
                    the Filter text will be processed into each device.
                  o If there are logfiles loaded into the workspace, the streams in
                    those files will be displayed in the Currently Loaded Devices
                    panel on the left:




                           Figure 35   Choose Your Devices


                  o Click the Add button to add a new device:




                           Figure 36 - Add Device Name Dialog


Introduction to A-SVS for Network Optimization                         Page 80
                                                                                           Introd uc tion to A-SVS for CDMA
                  o Enter the Device Name and the related Filter that identifies the
                    stream of interest within the logfile. The Device Name is a label
                    that has meaning to the user. The software determines whether
                    data from a stream should be loaded into the Device based on
                    whether the Filter text matches any text in the data stream
                    name. In this example, the Filter 1) uniquely identifies the
                    scanner stream in the file, while using an identifier that is
                    common to many types of logfiles. If the Filter field is left empty,
                    data from all streams will be loaded into the Device.
                  o Click OK to add the Device to the Device List.
                  o A Network Image template may contain multiple devices. Once
                    all the Devices have been entered, click Next to continue.

         Step 3     Choose Your Attributes:
                  o Select a Device from the panel on the right, and then use the
                    Add button to select the required attributes from the Attribute
                    Picker panel on the left.
                  o If you select an array attribute (i.e. EcIo_for_Nth_Best_Pilot[]),
                    a dialog will prompt you for the range of indices. Enter the start
                    and end values and click OK.
                  o In addition to standard analysis parameters, we recommend
                    adding the Independent        FileName parameter to each
                    Device in a Network Image. FileName can be used to trace

                     data points in the Network Image to the original source file. This
                     method is used to perform detailed analysis on problems
                     spotted in the high level Network Image.
                  o Attributes are assigned to one Device at a time. To duplicate
                    the attributes selected for one Device into another Device,
                    select the Device with the required attributes and click Copy.

 Reporting CDMA Network Performance
 The reporting features in Analyzer allow you to create high-level management
 reports based on your data. Two different mechanisms exist for creating for
 producing integrated, polished reports that can be used to analyze high-level
 network statistics or communicate test results in a professional format:

        Application Packages are a technology-specific series of reports that are
        installed automatically with every Analyzer installation. Application Packs
        are typically used to obtain a high-level overview of call statistics. They can
        be used when a professional, formatted output is required, but time
        constraints do not allow for the creation of a custom template.

        Reports are user-definable formatted outputs that make use of Analyzer s
        integration with Microsoft Excel. Reports may be included with an Analyzer
        installation (such as the CDMA Training Materials), but are not always
        included. Reports, unlike Application Packs, allow for formatted outputs of
        multiple streams of data. Use Reports when generating outputs for multiple
        streams of data and when you want to design a custom formatted template
        from scratch.

 This section describes the use of both reporting mechanisms, including
 running Application Packs, running pre-defined Reports, and creating
 custom Reports.

 Application Packages
   A-SVS contains Application Packages specific to each mobile technology
   supported by the software. The Application Packs are a series of reports, each
   focusing on a particular aspect of mobile network optimization. The Application
   Packs currently available for CDMA2000 1x users are:

         CDMA2000 1x Data Performance Benchmarking
         CDMA2000 1x Data Call Analysis
         CDMA2000 1x Downlink Data Rate Analysis
         CDMA2000 1x Uplink Data Rate Analysis
         CDMA Cluster Optimization
         CDMA Event Inspection
         CDMA Scanner Dist. Server Analysis
         CDMA Summary Reports

   Running Application Packs

   Once a data file is loaded, the Application Packages can be accessed in one of
   two ways:
      1.   Through the Analysis menu on the main menu.
      2.   By right-clicking on the stream name in the Workspace Browser
 Note: The Application Packs require Analyzer to be pointing to a valid cellrefs file in
 order to function properly.
 Once you have selected one of the Application Packs from the menu, an
 Application Pack window will appear. The window is divided into two panes. The
 top panel is called the Statistics Explorer, and it contains a summary of major call
 events and statistics for the selected stream. Information in the cell explorer is
 organized by serving site and sector.
 The bottom pane is called the Report Window and contains a list of available
 reports associated with the selected Application Pack. Once executed, the results
 of the reports can be saved, printed, and shown in their raw form in Microsoft
 Excel.

         actual collected values to target values for forward and reverse link
         parameters. NOTE: This report requires a merged forward and reverse
         link SuperStream
      2. Cluster Optimization Measurement Charts            Displays forward and
         reverse FER and combined EcIo in CDF and PDF format. NOTE: This
         report requires a merged forward and reverse link SuperStream

   Running Reports from an Application Pack

   As an example, we will run the Call statistics Summary report from the CDMA
   Summary Reports Application Pack.
      1. Open Phone & Scan 1.mdb if it is not already open in your workspace.
      2. Right-click on the phone stream in the Workspace Explorer, and
         choose CDMA Summary Report from the menu.

 Running a Pre-Defined Report

 Since Application Packs are built into the Analyzer, they may not exactly meet your
 team s reporting requirements. Additionally, App Packs can only be run on a single
 stream of data. Analyzer Reports allow you to create custom reports using
 Microsoft Excel, and those reports may include data from multiple streams.
 Reports from multiple measurement sources allow you to compare data collected
 simultaneously or look at your network before and after making a change.
 In this section, you will populate a pre-defined Analyzer Report template that
 contains multiple data streams. In the next section, you will create a custom report
 from scratch.
 To run the pre-defined report:
      1. From the Analyzer         main   menu     select   Workbook           Open
         Workbook/Report.
      2. Navigate to C:\Program Files\Actix\Analyzer\Reports and Open the
         report called CDMA Handset Comparison Final Summary.xls.
      3. Analyzer prompts you to select a data stream to replace the before
         stream. Select the handset stream from Phone & Scan 1.mdb and click
         OK.
      4. Analyzer then prompts you to select a second data stream. Select the
         handset stream from Phone & Scan 2.mdb and click OK.
      5. Analyzer will generate the report and launch Excel. Expect for this to take
         a few moments. When this process is complete, click on the Report tab in
         the Excel workbook and examine the formatted report.

Creating a Custom Report
 Creating your own formatted report template is as easy as viewing the data you
 require on a workbook, and then formatting the report page using Excel.
 The objective of this section is to create a simple report, like the one shown below,
 to display a histogram distribution and statistics for forward FER. Since FER is the
 parameter that provides the best estimate of user-perceived voice quality, the
 value of this parameter throughout a network is of great importance.

  Performing Custom Analysis in Analyzer
        You can create a wide variety of customized analyses using
        Analyzer. You may want to highlight potential voice or data problem
        areas, or test for common symptoms of bad radio link quality for the
        purpose of speeding up the analysis of data. Your customized
        analysis, called a query, can be saved in a Workspace and reused
        for future drive data. The queries can be created, accessed, and
        edited in the Workspace through the Analysis Manager.

        About Queries
        Queries are a means of searching and filtering data based on events
        and thresholds you define. Queries operate on binned data and are
        written using Boolean expressions and arithmetic operations
        containing data parameters from one or more data streams. Analyzer
        supports six types of queries:
               Filter Analysis
               Binned Query Analysis
               Cross Tab Query Analysis
               Event Query
               Statistic Analysis
               Histogram Analysis


        Analyzer supports the use of queries to assist in the detection,
        correction, and presentation of network problems. In this section a
        number of these analyses are used for examining various aspects of
        voice and data networks.

        All custom analyses can be saved for future use through the Analysis
        Manager:
                  Select Tools    Analysis Manager
                  In the Analysis Manager, select the Existing Analysis
                  tab
                  Select any queries that you wish to save and click the
                  Export button
                  Browse to a folder that you wish to save your query in.
                  Analyzer s default structure provides the C:\Program
                  Files\Actix\Analyzer\Queries folder for an easy place to
                  store queries.

                                                                                      Introd uc tion to A-SVS for CDMA
                  Name the *.aqf file Training_Class_Queries. All queries
                  created during training may be stored in the same file.
                  To import the queries into a new Analyzer session, go to
                  the Existing Analysis tab of the Analysis Manager and
                  select the Import button. Browse to find the *.aqf file in
                  which you saved your queries.



        Filter Analysis: Filtering on Poor Quality
        Sometimes it is desirable to examine only a subset of the data points
        collected in a logfile. We can use a filter to look only at those data
        points of interest to us.
        A filter analysis tests data on a single criterion and displays the data
        only if the criterion is met. This provides the engineer with a quick
        way to identify trouble areas in which to focus optimization efforts.
        In this case, we will filter all points with poor FER, and use the results
        to pinpoint where quality problems are occurring and try to determine
        what is causing them. You can create a filter query which highlights
        those points which have ForwardFER > 5% to identify all the
        locations on the drive with poor quality of service.
           1. Right-click on the handset data stream under Phone & Scan
              1.mdb and select Filter    Create a New Filter.
           2. For the Filter Name, enter PoorFER .

           3. Use the attribute chooser to select ForwardFER from the
              CDMA     Downlink Measurements group.
           4. For the operation, choose >=.
           5. For the Threshold, enter 5 .

                                 Figure 52 - Filter Wizard


           6. Click OK to create the filter. Analyzer will automatically apply
              the filter to any information already displayed in the
              workspace.
           7. Confirm that the query was created by going to Tools
              Analysis Manager and clicking on the Existing Analyses
              tab. The PoorFER filter should be listed under the Filters
              category.
           8. From the Existing Analyses tab, save the PoorFER Filter to
              the Training_Class_Queries.aqf file by selecting it and the
              Forward FER Advanced query and using the Export button.
              Multiple queries may be saved in one *.aqf file.
           9. Display any parameter (i.e. Ec/Io, FER, PNPrimary) on the
              map. Notice that only points with FER exceeding the defined
              threshold appear on the map. The filter has provided a quick
              way of illuminating trouble spots and focusing optimization
              efforts.

           10. Remove the filter from the map by right clicking on the
               handset data stream under Phone & Scan 1.mdb, selecting
               Filter, and unchecking the PoorFER filter. The filter can be
               reapplied at any time through the same method.




                    Figure 53 - Map of Data Filtered Using the PoorFER Filter



           In CDMA networks, areas with interference are typically identified
           as those locations experiencing poor FER but strong Ec/Io. Filters
           may be combined using Boolean operations in Analyzer to look at
           more than one condition at each data point.
            1. Create a new filter called StrongEcIo, which filters on data
               points where Ec/Io is greater than 8 dB.
            2. Apply the filter to the handset stream of Phone & Scan
               1.mdb.
            3. With the StrongEcIo filter applied, right click on the handset
               stream, select Filter, and make sure that the AND operator
               is selected with a bullet.
            4. Returning to the Filter menu, apply the PoorFER filter in
               addition to the StrongEcIo filter.
         What do the data points remaining on the map at this point
         indicate?
         Be sure to save the StrongEcIo filter, in addtion to the other
         queries you ve created, in your Training_Class_Queries.aqf file,
         making sure to select all of the filters and queries.

        Binned Query Analysis

        The Binned Query allows you to define a new parameter based on
        existing parameters, using functions and inequalities. The results of a
        binned query can be displayed on a map, chart, table, or workbook.

        ServingCellDistance in Miles

        By default, Analyzer displays the serving cell distance in meters. A simple,
        yet very useful example of a binned query is the conversion of the serving
        cell distance from meters to miles.

        Create the ServingCellDistance in Miles query using the Analysis
        Manager:
        1. Select Tools     Analysis Manager.
        2. Select the Binned Query icon in the dialog and click on New.
        3. For the Description, enter ServingCellDistance in Miles .

        7. Click OK to create the query.
        8. Click OK again to close the Analysis Manager.
        9. The query will appear in the Queries group under every data stream in
           the workspace. Under the handset stream, expand the Queries
           Binned Queries group.
        10. Right-click on the ServingCellDistance in Miles query and choose
            Display on Map to display the query results on a map.

        Pilot Pollution Query

        The Binned Query analysis allows you to create a new expression, as a
        parameter, based on existing parameters. This is useful for adding non-
        standard analyses, like pilot pollution, where each vendor has their own
        definition for the analysis.
        Mathematically speaking, the Ec/Io for the Nth Best Pilot data set is an
        array that contains Ec/Io data for all PNs measured at a given location in
        order from the strongest PN to the weakest. The array_count function
        counts the number of PNs in this array which have an Ec/Io > -15 dB. The
        query returns a 1 when the Pilot Pollution criteria are met and a 0 when
        they are not.
        In terms of the network, this query finds all bins where there were more
        than 4 servers above -15 dB. Thus, this query detects areas where there
        are multiple servers, no dominant server, and/or poor signal quality.
        Create the Pilot Pollution query using the Analysis Manager:
           1. Select Tools      Analysis Manager.
           2. Select the Binned Query icon in the dialog and click on New.
           3. For   the  Description,            enter     Pilot       Pollution
              Identification .

              We will create a custom parameter that counts the number of PNs
              above 15 dB at each point on the drive, and returns a value of
              True if it exceeds 3.
              The Expression is:
              array_count(EcIo_for_Nth_Best_Pilot[], >, -15)>=4


                1. In the lower right hand window, select array_count from the
                   list of functions. Notice the pop-up description for each
                   function. Double-click on the array_count function to add it
                   to the expression. The expression window now contains:
                       array_count(«attribute[]»,«operation», «expr»)
                2. Highlight the <<attribute[]>> parameter. In the lower left hand
                   window, step through the CDMA                 Pilot Measurement
                   group to find the attribute EcIo_for_Nth_Best_Pilot. Double-
                   click the attribute to add it to the expression.
                3. In place of <<operation>>, <<expr>>, enter > and            -15 .
                4. After the closing parenthesis, enter >=4 .
                5. In the format drop-down list, set the Format to Boolean.
                6. Click OK to finish creating the binned query. While still in the
                   Analysis Manager, take the opportunity to save the query to
                   the Training_Class_Queries.aqf file.
                7. Click OK to close the Analysis Manager.

        This query should be used to analyze Scanner data only.

        Look at the results of the query for a PN scanner on the map. Points with
        Pilot Pollution, as defined by the expression, will show up on the map as a
        Boolean 1. Points with no Pilot Pollution will show up as a 0. Add the
        Forward FER attribute (filtered for poor quality) from the corresponding
        handset data to the same map to see if a correlation exists. Change the
        FER style to be a star instead of a circle to make it show up more clearly.
        To change a parameter s style for all data points, right-click on the
        parameter in the legend and select Attribute Style. From the dialog,
        choose a new symbol, font and/or font size for each data point regardless
        of value.

        Do locations with pilot pollution also have poor forward FER?

        In some cases, you may be interested in looking at the number of PNs
        above the threshold at each location, as opposed to a Boolean value that
        designates data points where more than four PNs are above that
        threshold.

        How could you modify the Pilot Pollution Identification query you just
        created to give the number of PNs above 15 dB at each data point?

 The CDMA StateTip: Determining Serving PNs
 Determining the locations of pilot pollution in the network may be interesting, but
 this data is not useful unless you know which PNs are causing the problem.
 Once the problem PNs have been identified, you can perform adjustments to the
 network to resolve the problems. Analyzer contains a tool called the CDMA
 StateTip that may be used to identify the sources of pilot pollution.
 The CDMA StateTip is a feature that helps engineers analyze performance data
 from handsets and scanners. It helps identify the sources of pilot pollution and
 points out areas where there are discrepancies between the handset and
 scanner data leading to Neighbor List problems. The CDMA StateTip may be
 used in conjunction with the Pilot Pollution Identification query above to
 determine the sources of pilot pollution in a network.
    1. With the Pilot Pollution Identification query results still displayed on a
       map, view the CDMA StateTip, by selecting Tools     CDMA StateTip.
    2. To configure the StateTip, use the Select Handset Device and Select
       Scanner Device drop-down menus at the top of the StateTip window to
       select corresponding handset and scanner device streams. In class,
       select the Phone stream of Phone & Scan 1.mdb for the handset and the
       Receiver stream as the scanner.
    3. There are three view options available for the CDMA StateTip.
               Pilot Sets View- shows the pilots seen by the handset and scanner
               at any given bin and the serving set they fall under (active,
               candidate, neighbor). Keep in mind that active set measurements
               are made much more frequently than candidate and neighbor set
               measurements. Therefore, for a given bin, expect to see primarily
               active set measurements.
               Top N Pilots View- shows the top serving PNs as seen by both the
               handset and scanner.
               Top N Pilots Chart- shows the top serving PNs as seen by both
               the handset and scanner in a strip chart.
         Use the Select Another View drop-down list at the top of the StateTip
         window to select the Top N Pilots Chart.
    4. Use the Select arrow to click on a bin on the map in an area affected by
        pilot pollution according to the Pilot Pollution Identification query results.
        The StateTip will synchronize to the point.
        Note: In this example we align the StateTip with a data point on a map.
        The StateTip can also be aligned with any chart, table or message
        browser containing either handset or scanner data from the loaded
        devices)

    5. Check the list and notice the pilots that the handset and scanner can
       detect above 15 dB.
 Clearly, with 4 pilots detected above 15 dB, there is no dominant server. This is
 not uncommon in a market that is still heavily in the buildout stage. However, it
 does indicate that there is substantial sector overlap, which may cause future
 problems when new cells are brought on the air in the area.
 To address this pilot pollution problem and to try to prevent future problems,
 consider downtilting the offending sectors that are furthest from the problem
 area. Other possible changes include modifying antenna azimuth and antenna
 type to get extra RF energy out of the problem area. Before making any
 changes, the impact of downtilting and attenuation changes should be evaluated
 for each individual cell site.
 In addition to identifying PNs causing pilot pollution, the CDMA StateTip may
 help to resolve neighbor list problems. By viewing handset and scanner
 measurements side by side, it is possible to see if a PN is measured by a
 scanner but not by a handset. This condition often indicates a missing neighbor
 in a neighbor list. Alternatively, it may indicate a PN serving outside of its
 intended area. Either situation should be investigated, because strong PNs that
 are not detected by the handset lead to interference.

 Crosstab Query: Sorting by Data Rate
 Data sessions in a CDMA 1x network are assigned one of four data rate values
 based on the client application and on the loading of the network. Each data rate
 describes the maximum allowable throughput for the specified link during that
 session. The data rate options for the forward and reverse supplemental channels
 in a CDMA 1x data call are:
                       Data Rate       Allowable Throughput
                       1x              9.6    14.4 kbps
                       2x              19.2    28.8 kbps
                       4x              38.4    57.6 kbps
                       8x              76.8    115.2 kbps
                       16x             Up to 153.6 kbps


 In general, the more bandwidth intensive the application, the higher the assigned
 data rate. Since an e-mail or chat application requires relatively low bandwidth, a
 2x rate is likely to be assigned, regardless of loading of the network. On the other
 hand, a large-scale data download via FTP or HTTP may be assigned a 16x data
 rate providing that current network loading conditions allow.
 Because different data rates result in different data transfer performance, it may be
 desirable to sort throughput and RF statistics by data rate. An Analyzer crosstab
 query can be used to view statistics sorted by data rate, and to filter results on data
 rate. In this example, we will create a crosstab query to display RLP Throughput
 and App Throughput for both the uplink and downlink, sorted by data rate. The
 query results will then be displayed in the Statistics Explorer, which can also be
 used to filter other data views.

 Histogram and Statistic Query: Retransmit Rate
 In cases where RLP transmit throughput is low during an uploading operation, it
 may be of interest to examine the rate at which data frames must be retransmitted
 over the air interface due to errors or missing frames. Knowing the average
 retransmit rate throughout a logfile or the number of data points at which the
 retransmit rate is high may indicate whether the data network is responding
 properly in marginal RF conditions.
 Analyzer s Histogram and Statistic Queries are available to provide these analysis
 formats for custom expressions. Since the retransmit rate is not available as a
 standard logging tool output, it is necessary to use the Histogram and Statistic
 Query formats to provide results for this type of analysis.
    1. Create a new Binned Query to provide the RLP Retransmit Rate using the
       following parameters. Refer to page 88 for more information about the
       Binned Query.

 Saving Your Preferred Layout
        In Analyzer, the workspace includes all data display windows within
        the Analyzer application window, together with the Workspace
        Explorer. Saving a workspace in Analyzer allows you to save the
        following items:
              Window layouts
              Open files you are currently working with
              Custom analyses you have created
              Custom attributes you have executed
              SuperStreams you have created

         To save your workspace click File    Save Workspace As and
         give the file a name. The Analyzer file structure includes a
         Workspaces folder that can be used to hold your saved
         workspaces, though you can save a workspace to any location.

         A workspace created with Analyzer may be opened directly from
         the Windows Desktop. To start up Analyzer with a set of commonly
         used queries, simply save a workspace with the queries of interest,
         but no data files. The workspace may then be saved as a shortcut
         on the Windows Desktop. Double-click on the Desktop shortcut to
         open Analyzer with all of your frequently used queries in place.

 Importing Cell Site Data Using the Network Explorer
 The Network Explorer allows you to import network element data into Analyzer,
 creating a cell plan file called cellrefs.txt. It also lets you browse and edit this
 network information once it has been loaded into Analyzer. The Automatic Import
 feature provides an automated method of updating cell site information in Analyzer
 as changes are made to the network.
 This section describes how to import delimited data into Analyzer, and how to
 configure the Automatic Import tool.

      Importing Network Data
      The important thing to remember about Analyzer s network data import
      process is that the process requires two files:
      1. A delimited text file that contains unformatted data arranged in tabular
         form, with one row for each individual sector in a network.
      2. A blank file, containing only Analyzer header information, to be populated
         with formatted data.

      Obtaining Site Data in Tabular Format
      In order to import cell site data from your own network, you will need to obtain
      a delimited text file containing the data listed in the table below. To maximize
      the benefit Analyzer can bring to CDMA network analysis, the parameters
      listed in bold in the table on the following page are REQUIRED for cell data to
      function with logged data in the main workspace. All other parameters are
      optional.
      The data may come from a network database or a planning tool configuration
      file. As long as the data is in a tabular format with one row for each sector,
      Analyzer will be able to import the data.

      The figure below is an example of a delimited CDMA file that could be used to
      import a site list into Analyzer. Though the columns can be in any order for
      import into Analyzer, the figure shows all of the REQUIRED fields.
      Additionally, the Excel spreadsheet must be saved as a TEXT file for import
      into Analyzer.

      Guidelines for Formatting Tabular Data
      Although Analyzer does not require cell site data fields to be listed in a
      particular order, following these guidelines will provide the best results:
      1. The Site ID field must contain a unique value for each site location.
         Beware of non-unique Site ID's - that is, entries that have multiple sets of
         lats/longs for the same Site ID. Non-unique Site ID's will result in site
         markers appearing on the map without sector wedges. Site Names need
         not be unique - they are used for labeling purposes only.
      2. Position information must be accurate in order for Analyzer to display sites
         in the correct location on the map. Longitudes that have a 'West' notation
         should be represented as a negative decimal, as should latitudes with a
         'South' notation. Sites will appear skewed on the map if the latitude and
         longitude fields are transposed.

      Obtaining the File to be Populated With Formatted Data
      Before importing new cells into Analyzer, ensure that Analyzer is pointing to a
      valid cell site database.

             A valid cell site database is a text file in which the first line contains the
             text below:

                             ; #NetworkData       datafile

             Every Analyzer installation comes with a clean file called cellrefs.txt
             located in the directory called:

                  C:\Program Files\Actix\Analyzer\Bin\Cellrefs

             The file to be populated need not be named cellrefs.txt . We
             recommend renaming this file with a meaningful name in order to
             prevent the file from being overwritten during reinstallation.

      To point the Analyzer to the file you wish to populate with the new cell site
      data, use the File Location line in the Tools     Preferences dialog. See the
      section on Loading Cell Site Data earlier in this document for more details.

      Importing the Data
      Once you have obtained your cell site database in delimited format and
      pointed Analyzer to a valid cellrefs file, you are ready to open the Network
      Explorer and import the site information.
      1. To access the Network Explorer select Cells        Network Explorer.




                             Figure 67 - Network Explorer Window
      The Network Explorer display consists of two panels. The left panel contains
      a tree view of the network element data. The right panel shows details about
      relevant parameters for the current selection. If you have pointed Analyzer to
      a cellrefs file containing only header information, you will not see any cell site
      data at this time.
      2. On the toolbar select Import       Import From New Template to open the
         Import dialog.
      3. Select the appropriate network data file and click Open to display the
         Import Settings dialog.

      4. Give the Template a meaningful Template Name.
      5. Check the appropriate Delimiter.
      6. In most cases, the default information under the General Settings and
         Coordinate Information headers will apply. Adjust these settings if
         necessary.
      7. Click Next.

      Updating Cell Site Data
      There are two convenient ways to update cell plan information in Analyzer:

         Minor cell plan changes (a few azimuths, PNs, etc.) can be modified
         directly from the Network Explorer. Simply browse to find the site and
         sector of interest and double click on a single parameter to activate the
         text. Be sure to save the modifications before exiting the Network
         Explorer!

         If the cellplan file is updated (multiple sites added, complete frequency
         retune), use the Automatic Import feature to detect changes to an existing
         cell plan and import the updated cell site file into Analyzer. Instructions for
         using the Automatic Import feature follow.

      Automatic Import of Cell Site Data

      The Automatic Import feature detects changes to cell plan data and updates
      the configured site data every time Analyzer is opened.

                                                                                       Introd uc tion to A-SVS for CDMA
      To use the Automatic Import feature:

      1. From the Analyzer main menu, select Tools       Preferences.
      2. Expand the Automatic Import option under Cellrefs and select the
         Enable Automatic Import option.
      3. Select the Automatic Import Input File. This is the text file that contains
         your delimited site data.
      4. Select the Automatic Import Template. Once a template has been
         created, a new Analyzer workspace must be started in order for that
         template to appear in this list. To use a template created on another
         computer, copy the template of interest from the C:\Program
         Files\Actix\Analyzer\Bin\Cellrefs\Templates directory to the same
         directory on your machine.
      5. Click OK to exit the Change Preferences dialog. A message will appear
         that Automatic Import has been enabled and that your currently loaded
         cellrefs will be overwritten the next time Analyzer is restarted.


      Once Automatic Import is configured, any changes to the Automatic Import
      Input File will be detected, and will be changed accordingly in your Analyzer
      cell site file each time Analyzer is opened.

 Using the CDMA Toolkit to Optimize Specific CDMA Network
 Parameters

        The CDMA Toolkit provides a series of analyses based on best-practice
        network optimization techniques. Each solution uses PN scanner data to
        optimize your network settings, and can be configured to meet the needs of
        your network and your organization. The analyses included in the CDMA
        Toolkit that are discussed in this section are:

              Optimize Search Windows

              Optimize Neighbor Lists

              Evaluate Coverage

      The following sections describe the general operation of the CDMA Toolkit
      and include instructions for running each of the specific analyses.

        Exploring the CDMA Toolkit

        The CDMA Toolkit contains analyses for investigating search window sizes,
        neighbor lists, and site coverage based on data collected with the PN
        Scanner.
        Before attempting to run a specific analysis, familiarize yourself with the
        CDMA Toolkit by performing the following steps:

              To view the Toolkit, select Tools    CDMA Toolkit from the Analyzer
              main menu.
              The taskbar at the top of the Toolkit shows that the Optimize Search
              Windows analysis appears as the default analysis. You will see five
              icons that serve as the buttons for selecting specific functions within
              the analyses. The Help and Configure Settings icons are used
              when setting up an analysis. The other icons list reports that describe
              the results of the analysis. The icons are arranged so that you
              progress downward, first modifying or reviewing the configuration
              settings, then running the analysis, and finally reviewing the results
              through one or more reports. The specific use of each button is
              described in detail for each analysis in the following sections.
              Each available analysis within the Toolkit contains its own taskbar.
              Click another taskbar to view another analyses. Notice that each
              analysis has a similar series of icons, which guide you through the
              setup, running, and reporting of data.

        The type of data required to run each analysis is described in the individual
        section for each analysis. As with all engineering analyses, there are
        caveats and restrictions on the applicability of the CDMA Toolkit analyses.
        In addition, the accuracy of the results is dependent on the quality and
        volume of input data. To get the best results from these analyses, ensure
        you are using an up-to-date version of cell site data that accurately reflects
        the network status and parameter settings at the time of the drive. In
        addition, the quality of the analyses will be impaired if a relatively small
        amount of drive test data is used.
        Please study the contents of the Help File under CDMA Toolkit to properly
        understand the analysis methodology and restrictions, and the potential
        sources of error. To access the help files, click on the Help button in the
        CDMA Toolkit:               . Analysis methodology is also described in
        Appendix C of this document.

        Using CDMA Toolkit for Search Window Analysis
        You can minimize the number of occurrences of dropped calls, failed
        initiations, and poor voice quality by setting the search windows to their
        optimal size. The search window analysis shows the minimum active set
        search window size (SRCH_WIN_A) and neighbor set search window size
        (SRCH_WIN_N) required by each sector, based on pilot delay data



Introduction to A-SVS for Network Optimization                          Page 137
                                                                                            Introd uc tion to A-SVS for CDMA
        collected in PN Scanner drive-test logfiles. The algorithm used to determine
        optimal search window sizes is described in detail in Appendix C.

        In preparation for running the Optimize Search Windows module of the
        CDMA Toolkit:
             1. PN Scanner data for a region of your network must be open in the
                current Analyzer workspace. This data should include
                comprehensive drive routes around the sites that you wish to
                optimize. The more data points included in each logfile, the more
                accurate the trends that Analyzer extracts from the data.
             2. Analyzer must be pointing to a valid cellrefs file that contains data
                for all of the sites included in the PN Scanner data. Search window
                size data is used if available in the Audit Report, but is not required
                for the analysis to run correctly.

        To configure Analyzer to run the Optimize Search Windows analysis
        through the CDMA Toolkit:
             1. Open the CDMA Toolkit by selecting Tools           CDMA Toolkit from
                the Analyzer main menu.
             2. The Optimize Search Windows analysis appears as the default
                analysis in the toolkit. Verify this by checking that the task bar at the
                top of the toolkit reads Optimize Search Windows
             3. If you want additional information on the analysis methodology of
                the Optimize Search Windows analysis, click on the Help icon.
             4. Depress the icon labeled Configuration Settings to configure the
                settings that Analyzer will use when running the analysis. The
                Configure Search Window Settings dialog will open to the
                General tab. Set each of the search window analysis settings:
                        Ec/Io Threshold Only scanner measurements above this
                        user-defined threshold will be included in the analysis.
                        Minimum Number of Measurements Only sectors which
                        have been measured above the Ec/Io threshold at least this
                        many times will be included in the analysis.
                        Maximum Distance Measurements made on servers that
                        are farther away than this user-input distance will not be
                        included in the analysis. Keeping this number relatively low
                        helps to avoid search window size recommendations that
                        are unnecessarily large.

        5. Switch to the Data tab of the Configure Search Window Settings
           dialog. If not all of the logfiles open in the workspace are shown in the
           window, press the Refresh List button. Select all PN Scanner streams
           on which to run the analysis. Hold down CTRL to select multiple
           streams.
        6. Press OK to exit the Configure Search Window Settings dialog.

        Once the configuration settings have been completed, run the Optimize
        Search Windows analysis and view the reports:
        1. Select the Summary Report, Audit Report, or Details Report by
           clicking on the icon next to the report name:
                  The Summary Report lists suggested Search Window settings
                   for each sector included in the analysis based on the PN scanner
                   data.
                  The Audit Report lists the differences between suggested
                  settings and current network configuration according to data
                  imported in the cellrefs file. If current network search window
                  settings are not included in the cell site file Analyzer points to, this
                  report will still run, but will list every search window size
                  suggestion as a difference.
                  The Details Report contains a series of views, which show the
                  scanner measurements in graphical format upon which the tool s

                   search window setting suggestions are based for each individual
                   sector.
        2. Verify the files to be included in the analyses and specify any additional
           files in the data tab of the Configure Search Window Settings dialog that
           appears.
        3. Press OK to exit the dialog and run the report. Analyzer will process the
           data and the selected report will appear. If warnings appear, see the
           Note below.

        Note: Analyzer may post warnings that some cell sites are not found in the
        cellrefs file. This indicates that not all cell sites that have been measured in
        the data file are included in the current cellrefs file. Analyzer cannot make
        recommendations on incomplete data, but the analysis will run correctly,
        including all data points for which a valid cell site reference exists. Press OK
        to bypass each warning.

        Using CDMA Toolkit for Neighbor List Analysis
        The Neighbor List Analysis lets you quickly and easily generate prioritized
        neighbor lists for multiple sectors using measured Ec/Io data from PN
        Scanner drive test files. The Neighbor List Analysis can compare
        measurement results with actual neighbor lists and recommend optimal
        modifications to current neighbor lists. The analysis ensures that all pilots of

                                                                                            Introd uc tion to A-SVS for CDMA
        appropriate strength will be included, and that the neighbor list will be limited
        to those pilots likely to engage in handoff. As new sites are added to mature
        systems, or as the propagation environment changes due to increased
        traffic loading, the Neighbor List Analysis can save significant time in the
        generation of new optimal neighbor lists. The algorithm used to determine
        neighbor list recommendations is described in detail in Appendix C.

        In preparation for running the Optimize Neighbor Lists module of the
        CDMA Toolkit:
              PN Scanner data for a region of your network must be open in the
              current Analyzer workspace. This data should include comprehensive
              drive routes around the sites that you wish to determine neighbor lists
              for. The more data points included in each logfile, the more realistic
              the trends that Analyzer extracts from the data.
              Analyzer must be pointing to a valid cellrefs file that contains data for
              all of the sites included in the PN Scanner data. Neighbor list data is
              used if available in the Audit Report, but is not required for the
              analysis to run correctly.

        To configure Analyzer to run the Optimize Neighbor Lists analysis through
        the CDMA Toolkit:
           1. Open the CDMA Toolkit by selecting Tools           CDMA Toolkit from
              the Analyzer main menu.
           2. Select the Optimize Neighbor Lists task bar to activate this module.
           3. If you want additional information on the analysis methodology of the
              Optimize Neighbor Lists analysis, click on the Help icon.
           4. Depress the icon labeled Configuration Settings to configure the
              settings that Analyzer will use when running the analysis. The
              Configure Neighbor List Settings dialog will open to the General
              tab. Set each of the neighbor list analysis settings:
                    Ec/Io Threshold       Only scanner measurements above this
                    user-defined threshold will be included in the analysis.
                    Minimum Number of Measurements Only servers that have
                    been measured at least this many times will be included in the
                    analysis.
                    Maximum Distance Measurements made on servers that are
                    farther away than this user-defined distance will not be included
                    in the analysis. Keeping this number relatively low helps to
                    avoid search window size recommendations that are
                    unnecessarily large.
                    Maximum Number of Neighbors The neighbor list for any
                    server will not exceed this number.

              the window, press the Refresh List button. Select all PN Scanner
              streams on which to run the analysis. Hold down CTRL to select
              multiple streams.
           6. Press OK to exit the Configure Neighbor List Settings dialog.

        Once the configuration settings have been completed, run the Optimize
        Neighbor Lists analysis and view the reports:
        1. Select the Summary Report, Audit Report, or Details Report by
           clicking on the icon next to the report name:
                  The Summary Report gives a prioritized list of neighbors for
                  each sector that was seen as a best server for at least the
                  minimum number of data points.
                  The Audit Report lists additions and deletions to current neighbor
                  list settings, based on the neighbor list data in the cellrefs file. If
                  current network neighbor list settings are not included in the cell
                  site file Analyzer points to, this report will still run, but will list
                  every suggested neighbor as an addition.

        Using the CDMA Toolkit for Coverage Evaluation
        The steps required to run each of the analyses in the CDMA Toolkit are very
        similar. Since the previous sections have described in detail the steps used
        to run the Optimize Search Windows and Optimize Neighbor Lists
        analyses, this section will take a different approach. This section describes
        the Coverage Evaluation analysis module of the CDMA Toolkit as a case
        study using a specific set of data.
        The Evaluate Coverage analysis lets you quickly find the optimal settings for
        EIRP or forward path attenuation in a CDMA network. EIRP or forward path
        attenuation can be modified to mitigate pilot pollution and coverage
        problems that commonly occur in CDMA systems. Forward path attenuation
        is attenuation applied only to channels on the forward link of the CDMA
        system. Forward path attenuation can be modified through a variety of
        mechanisms specific to each infrastructure vendor.
        Other techniques for mitigating pilot pollution and coverage problems
        include the addition of new sectors, and modifications to antenna type,
        azimuth, and downtilt. Currently, the Evaluate Coverage analysis can only
        model forward path attenuation modifications.

        The analysis is based only on measured pilot data, and ignores power
        received from other CDMA channels. Thus, the analysis mimics the
        unloaded pilot measurements that are typically performed as the first stage
        of cluster optimization. This technique is necessary because in order to
        consider the impact of loading, traffic channel power must be modeled.
        Traffic channel power is a dynamic value based on the number of users in
        the system and their propagation path to each base station. The analysis
        uses PN Scanner drive test data that provides Pilot channel received
        signals levels for each PN offset. However, the PN Scanner cannot
        measure the traffic channel power received from each sector independently.
        Therefore, it is not possible to know how a forward link attenuation change
        at a given site will affect the received traffic channel power measured by the
        scanner.

        Typically, one must analyze drive test data to detect coverage and
        interference problems, and then determine a potential change to be made to
        EIRP or forward path attenuation to mitigate the problem. Once the changes
        have been made, new drive tests are performed to determine if the
        hypothesized changes have had the desired effect. If the effect of the
        change is undesirable, additional changes and tests are performed.

        Since this analysis is designed to simulate changes that can be made on a
        network, we must strip away CDMA channel energy from the measurements
        that are load dependent. This will leave only the pilot channel measurement.

                                                                                        Introd uc tion to A-SVS for CDMA
        For further details on the algorithm used to perform the coverage
        evaluations on the data, see Appendix C.
           1. Be sure that Phone and Scan 1.mdb is loaded.
           2. In the CDMA Toolkit, select the Evaluate Coverage analysis.
           3. Click on the Configure Settings button. Notice that the following
              Analysis Settings are available for configuration:
                   Ec/Io Pilot Pollution Threshold This threshold is used to tell
                   the analysis to ignore measurements too weak to contribute to
                   pilot pollution. For unloaded data, this is typically around 9 dB.
                   Ec/Io Coverage Threshold             This threshold is used to
                   determine which measurements provide service to a particular
                   location. For unloaded data, this is typically around 4 dB.
                   Noise Set this to the thermal noise floor of the handset you
                   wish to emulate.
                   Minimum Number of Measurements           Only servers which
                   have been measured at least this many times will be included in
                   the analysis.
                   Maximum Distance Measurements made on servers that are
                   farther away than this user-input distance will not be included in
                   the analysis. Keeping this number relatively low helps to avoid
                   search window size recommendations that are unnecessarily
                   large.
           4. Make sure that the minimum number of measurements bins is set
              to 5 bins and that the maximum distance to servers options is set
              to 20 km. Click OK when finished.
           5. Click on Summary Report and select the scanner stream from the
              loaded file.
              The report will be generated. The output will give you a list of sites,
              which you can expand to show the sites causing and receiving
              interference.
           6. Examine the report and note that the following sites seem to be
              receiving the most interference and find these sites on the map.
                   Site 28, Sector 2
                   Site 7, Sector 2
           7. In the row for Site 28, Sector 2, check Show Cells to view the
              sectors that the site receives interference from and interferes with.
              PN 150 interferes with Site 28, Sector 2. A quick glance down the PN
              list in the report shows that PN 150 comes from Site 8, Sector 2.

                                                                                      Introd uc tion to A-SVS for CDMA
           8. Use the Scenario Tool, described below, to determine whether the
              problem can be fixed by providing 8 dB of attenuation to the
              offending sector.

           Creating a Scenario

           1. In the CDMA Toolkit, select the Evaluate a Scenario button.
           2. Choose the scanner stream to open the Evaluate a Scenario
              window.
           3. Find Site 8 in the list of cells and select Sector 2 on the site.
           4. Use the arrows in the Forward Transmit Power Attenuation field to
              dial in 8 dB of attenuation for Sector 2 of Site 8.
           5. Click Report the Changes.
           6. Press the Report button to show a summary of changes that occur
              with the attenuation parameter change. A Coverage Delta report will
              be generated and you should see much less interference contributed
              to PNs 132, 246, 129 and 114 by Sector 2 of Site 8. Examine the list
              of PNs and Sites and find that PN 129 corresponds to Site 28, Sector
              2.
              Note that 8dB of attenuation is significant so make sure that the
              coverage of Site 8, Sector 2 is not compromised. This can be verified
              with data from that portion of the network.

 CDMA 1x Analysis          Data Throughput vs. RF Performance

        A key activity for CDMA 1x drive test data is the comparison of data
        throughput to radio link performance. The radio link is the critical path for
        data in a 1x network. It is important to understand the effects of a poor radio
        environment on data throughput, and the limitations of the data network
        when radio conditions are not favorable.

        Multiple Analyzer views can be synchronized to allow for the comparison of
        the radio link and data throughput. For example, throughput trends
        displayed on a chart can sync with FER or Mobile Rx Power on a map. The
        cdma2000 StateTip view allows for a more detailed view at any data point.
        The cdma2000 Data Testing StateTip juxtaposes throughput statistics,
        radio link information, and fundamental and supplemental channel statistics.




                                  Figure 78: cdma2000 StateTip

                                                                                    Introd uc tion to A-SVS for CDMA
        Use the cdma2000 StateTip to examine the relationship between FER and
        throughput in the CDMA 1x Data Willtech 1.0401 file:

        1. From CDMA 1x Data            Willtech 1.0401, place ForwardFER and
           Anchor_Transfer events onto a map.
        2. Place               RLP_Rx_Throughput_Instantaneous               and
           RLP_Tx_Throughput_Instantaneous on a chart.
        3. Select Tools     CDMA StateTip.
        4. Use the Select Another View drop down menu to choose cdma2000
           Data Testing.
        5. Use the Select Handset Device drop down to select the handset stream
           from the Willtech 1x file.
        6. Tile your views in the workspace.
        7. Select a point on the map or chart.          Notice that the StateTip
           synchronizes to provide throughput, radio link, fundamental, and
           supplemental channel information at that point.

        In some cases, the cdma2000 StateTip may provide more information than
        you require. If that is the case, recall that Analyzer Stateforms can be
        modified or created to meet your needs for CDMA 1x analysis.

        For example, minor modifications to the existing CDMA Handset.axw
        Stateform to add RLP Rx and Tx Throughput to the existing radio
        parameters:




             Figure 79: CDMA Handset Stateform Modified to Include RLP Throughput

      The modified CDMA Handset Stateform provides throughput and radio
      link information in a single view. In some cases, more detailed
      information about the data network may be required in order to
      determine whether a component of the IP network is not working
      properly. The CDMA 1x Throughput Stateform, pictured below, was
      built from scratch to provide a comparison of throughput at different

      layers of the IP stack. Ideally, the RLP throughput should be the
      highest value, followed by RLP2, PPP, TCP and App Throughput. Due
      to data collection hardware constraints, this may not always be the
      case.

      All existing Stateforms can be found in your C:\Program
      Files\Actix\Analyzer\StateForms. See page 51 for more information on
      modifying existing StateForms and creating new StateForms from
      scratch.

 Appendix A            CDMA Decode Settings
        The following decode settings for CDMA data are found in the Tools
        Preferences dialog.
           Minimum Valid Signal Level (dBm)           Defines the minimum threshold for which a
           received signal strength is valid. On loading a log file, Analyzer will filter out signals
           below this user-defined range.
           Ec/Io Threshold for Delay (dB) Used to calculate the threshold at which multipath
           components are counted in the delay measurements for PN scanner data.
           Scan Resolution (Chips) - Defines how often handset measurements are reported,
           measured in chips. The Scan Resolution is typically ½ chip.
           Number of Multipaths - Defines the number of multipaths that will be extracted and
           displayed in the Workspace Explorer.
           Scanner Scan Resolution - Defines how often scanner measurements are reported,
           measured in chips
           Pilot Increment - Used to calculate the PN Offset (units of 64 chips) associated with
           the PN Phase (units of chips) data reported in the CDMA air-interface messaging. PN
           Offset is calculated by dividing the PILOT_PN_PHASE by 64 and then rounding to the
           closest integer multiple of the PN increment entered. This feature forces all PN Offsets
           calculated to be part of a valid PN reuse plan.
           Too Many Neighbors Threshold - Defines the maximum number of entries in the
           neighbor lists. When neighbor list entries in the air interface messaging exceed this
           threshold, an event (TooManyNeighbors) is displayed in the Workspace Explorer.
           Weak Ec/Io Pilot Threshold - Defines when the best server pilot has dropped beneath
           a tolerable threshold and is considered weak. This displays an event (WeakPilotAlert)
           in the Workspace Explorer.
           Display Cell Identity as Hex - Check the box to display the Cell Identity (CI) in
           hexadecimal (rather than decimal) in the Message Browser.
           No of Frame Errors in a Burst - Defines the size of a burst for Burst Error Rate
           calculations (time series parameter: For_FBER).
           Searcher Threshold - This control is no longer used and will be removed in the next
           Analyzer release.
           Scanner Ec/Io Threshold (dB) Defines the minimum threshold for which a signal
           strength received by a scanner is valid. On loading scanner data, Analyzer will filter out
           signals below this user-defined range.
           Use 20ms resolution for CDMA - Displays messages with individual frame granularity
           for Qualcomm MDM and MDM-based formats.

        Overview of CDMA Event Detection




                               Figure 84: Event Detection Diagram


        The Analyzer s CDMA event detection engine is used to identify key network
        events in CDMA IS-95, IS95-B and IS.2000 networks. This is accomplished by
        monitoring the air interface messaging. Using the air interface messaging, the
        handset s state can be tracked as it moves between Idle, Origination, and
        Dedicated states.
              Idle State This is the state that the phone is in before a call is originated
              or received. After a call is terminated through normal or abnormal means, it
              returns to the Idle State.
              Origination State This is the state that the phone is in after an Origination
              or Page Response is sent on the access channel, but before the forward
              and reverse traffic channels are active.
              Dedicated State (Conversation) This is the state that the phone is in after
              transmission has started on both the forward and reverse traffic channels.


             Note    The start state is the default state for all phones until an air interface
                     message is received. Based on this message, the phone is immediately
                     transitioned to the appropriate state. This is to account for log files where
                     the phone is already in origination or conversation.

            Call Completed         This attribute indicates successful outgoing call
                                   terminations triggered by the following sequence of
                                   messages:
                                            OutgoingCallOk or IncomingCallOk
                                            Followed by a Release Order (A FTCH or RTCH
                                            Release Order with Release Type = Normal)

                                   Note: In order for a call to successfully terminate, FTCH and
                                   RTCH Release Orders must be sent. Due to throughput issues
                                   during logging, one of these messages is often discarded. To
                                   account for this, the Analyzer will determine that a call was
                                   successful if either of these messages is present.


            Call Dropped           This attribute indicates abnormal call terminations triggered by

                                             Followed by a return to the Sync Channel

                                   Note: In order for a call to successfully terminate, FTCH and
                                   RTCH Release Orders must be sent. Due to throughput issues
                                   during logging, one of these messages is often discarded. To

                                    transfer. The anchor transfer is triggered by a change in the
                                    supplemental channel s active set. Analyzer monitors the PNs
                                    in the Extended Supplemental Channel Assignment Message
                                    and triggers an anchor transfer when the PN in the ESCAM
                                    message changes.



            For Anchor              There is a delay associated with a transfer from one anchor to
                                    another. This delay is the time between when the
            Transfer Delay          supplemental channel stops transmitting on the first anchor to
                                    when it starts transmitting on the second anchor.



            For FCH to SCH          The time delay between the setup of the FCH and the SCH on
                                    the forward link. This is the time period between the Forward
            Delay                   Traffic Channel Extended Channel Assignment Message, and
                                    the Forward Traffic Channel Extended Supplemental Channel
                                    Assignment message.




             Note    When determining hand-off events, the HDM_SEQ and LAST_HDM_SEQ
                     counters are used to ensure that the correct events are identified.

    Optimize Search Window Analysis
    The Search Window Analysis performs the following algorithm on each data bin
    to determine optimal active and neighbor search window settings for each site
    calculated:

    1. The analysis determines which sectors serving the bin are to be considered
       valid for further analysis. Valid serving sectors must be measured at or
       above a user-defined Ec/Io threshold, and must be within the user-defined
       maximum distance away from the data point.

    2. Active Set Search Window Calculation: The maximum multipath Delay
       Spread of the valid serving sectors is calculated. This value is multiplied by
       2 to allow for the double-sided nature of the search window, and is then
       assigned to ALL remaining serving sectors at that data point.
       After all data points have been analyzed, the delay measurements are
       aggregated by sector. For each sector, the recommended minimum active
       set search-window size is determined by calculating the maximum of the
       Delay Spread assigned to that sector at any data point. Only sectors that
       have been measured more than a user-defined number of times will be
       included in the final report.

    3. Neighbor Set Search Window Calculation: The minimum Delay to First
       Multipath is calculated for all valid serving sectors. The maximum of the
       sums of the Delay to First Multipath and Delay Spread is calculated for all
       valid serving sectors. Lastly, the minimum Delay to First Multipath is
       subtracted from the Maximum of the sums of the Delay to First Multipath
       and Delay Spread. This number is multiplied by 2 to allow for the fact that
       the search window is double-sided as follows:
           2*Max{(Delay to First Multipath+Delay Spread) for all PNs}-Min{Delay to First Multipath for all }

        Essentially, this calculation simulates the mobile deriving its timing
        reference from the earliest arriving multipath and determines the maximum
        Neighbor Set search window size required by the pilots measured in the bin.
        This value is stored for all thresholded pilots serving the bin.

        After all data points have been analyzed, the delay measurements are
        aggregated by sector. For each sector, the recommended minimum
        neighbor set search-window size is determined by calculating the maximum
        of the calculation above, assigned to that sector at any data point. Only
        sectors that have been measured more than a user-defined number of times
        will be included in the final report.

    Optimize Neighbor List Analysis

    The Neighbor List analysis performs the following algorithm on each
    measurement bin along the drive test route:

        1. The analysis calculates the Ec/Io from all sectors serving that bin. The
           sector with the highest Ec/Io at a data point is considered the server at
           that data point.
        2. All other sectors with Ec/Io above a user-defined threshold will be
           recorded as a potential neighbor to the server at that data point.

    After all bins have been analyzed, neighbor lists are generated for each sector
    seen as the server more than a user-defined minimum number of times. The
    neighbor list for each server is prioritized by the number of times a particular
    neighbor was seen. The more times a neighbor was seen for a server, the
    higher it will appear on that server s prioritized list. By virtue of the analysis,
    neighbor lists are automatically symmetric.

    Evaluate Coverage Analysis

    The Evaluate Coverage analysis performs these steps for each measurement
    bin along the drive test route:

        1. The analysis calculates the Ec/Io above a user-defined threshold from all
           sectors serving that bin.
        2. Interference from only pilot signals, Ipilot, is calculated for the bin by
           summing Ec from all serving pilots.
        3. Unmodified, unloaded Ec/Io is calculated by dividing Ec by Ipilot for each
           sector.
        4. Ecmod for each sector is determined by applying the attenuation
           modifications entered by the user to the Ec measured for each sector.
        5. Modified interference from only pilots signals, Ipilot,mod, is calculated for
           the bin by summing Ecmod from all serving pilots.
        6. Modified, unloaded Ec/Io is calculated by dividing Ec,mod by Ipilot,mod for
           each sector.
