 3          1.1 Introduction and Purpose
 4   This document provides an overview of what carriers have agreed are basic requirements for
 5   exchanging coverage footprint information. It is a guideline for all CDMA network operators to use
 6   to create and distribute coverage maps. It is not the intent of this whitepaper to change or modify
 7   any of the confidentiality or other provisions in existing agreements between carriers. The
 8   exchange of coverage information between carriers is subject to the terms and conditions
 9   contained in any roaming agreement, non disclosure agreement or any other agreement between
10   such carriers.

                                           display of geographic knowledge, which is represented using a series of

      Projection                         A method by which the curved surface of the earth is portrayed on a flat
                                         surface. This generally requires a systematic mathematical transformation of
                                         the earth's graticule of lines of longitude and latitude onto a flat surface.

      RF Coverage Map                    A real world projection that illustrates the degradation of radio waves as they
                                         travel from a given point. Electromagnetic wave propagation along with
                                         topography, vegetation and transmitter settings all contribute to the size and
                                         shape of the RF footprint.

 3   document.


 4          1.4 General Requirements

 5   Carriers have agreed to following minimum requirement no matter which coverage format is
 6   exchanged:

 7             Coverage maps should be an illustration of where a carrier provides CDMA service to
 8              their own customer. The following are recommended to be included in a separate word
 9              document so that the map can be as clean as possible. See Appendix 1.

10                 o    The map title

11                 o    The map projection

12                 o    The RF signal level provided

13             RF and Marketing Coverage maps are acceptable while licensed coverage maps are not
14              acceptable.




15


16             A separate coverage map should be provided for each service (Voice, SMS, Data (1x,
17              EVDO, RevA) at frequency which is available. Below is an example list of the maps that
18              should be shared assuming a carrier provides both 850 & 1900Mhz coverage as well as
19              voice, 1xRTT and EVDO coverage;

20                 o    850Mhz voice coverage


     Ref Doc153, Ver 4                             October 2007                                                            5
 1               o    850Mhz 1xRTT coverage

 2               o    850Mhz EVDO coverage

 3               o    1900Mhz voice coverage

 4               o    1900Mhz 1xRTT coverage

 5               o    1900Mhz EVDO coverage

 6          The same naming convention should be used for each file. The file name should be as
 7           follows; Carrier name underscore frequency underscore service underscore month date
 8           year dot file extension. An example of a correct file name is
 9           ACMEDigital_850voice_01012007.tab


10       1.5 Exchange Format Requirements

11   At a minimum, carriers have agreed to exchange image files of coverage maps. In addition, any
12   city list that a carrier provides to its own customers should be provided to a roaming partner. An
13   appropriate list of cities should be determined by the serving carrier. No minimum population
14   requirements have been set.

15   Geographic Information Systems files should be made available if the carrier can produce those
16   files. The following are the requirements based on which format is submitted:


17       1.5.1 Geographic Information System file – Carriers support the following
18       mapping software file types as the recommended format for exchanging coverage
19       maps;

20          ERSI – An ERSI file with one of the following extensions that geographically represents where
21           coverage is available. Extensions include .SHP, .SHX, .DBF, and ,E00 files

22          MapInfo – A MapInfo file with one of the following extensions that geographically represents where
23           coverage is available. Extensions include .TAB, .DAT, .ID and .MAP files

24          It is recommended that carriers who are able to share GIS files provide coverage based on
25           broadcast SIDs. By providing information at this level, carriers assist their partner in acquiring their
26           network in a timely and accurate manner which results in more revenue for both carriers.

27               o    SID – The files should be submitted so that unique SIDs are identified independently of
28                    other SIDs

 1        1.5.2 Image files - The following are requirements if carriers are exchanging
 2        coverage maps in image files:
 3          Map must be in color
 4          Map should be in high resolution with greater than 300 dot per square inch.
 5          For regional or market level maps a minimum of the six (6) largest cities or destinations within
 6           a coverage area must be labeled. No cities are needed to be displayed for country level maps.
 7          Any of the following formats are acceptable image file formats:
 8               o .AI – Adobe Systems
 9               o .CDR – Coral Draw
10               o . CPC – Cartesian
11               o .GIF – Graphic Interchange Format
12               o .JPG/.JPEG – Joint Photographic Group
13               o .PICT/.PIC/.PCT – Apple
14               o .PSP – Paintshop Pro
15               o .TGA/.TPIC – Truevision
16          RF Coverage files which are usually images files are also acceptable
17               o Planet




18




19        1.6 Exchange Method

20   While carriers can e-mail coverage maps the recommended method is to use the on line, free CDG CDMA
21   Roaming Information Exchange Tool (CRIET) which is found at this address: www.cdg.org/CRIET .


22        1.7 Exchange Frequency
23   Carriers whose coverage is changing rapidly should update and distribute maps on a quarterly basis. Maps
24   should be updated a minimum of once a year even if coverage isn’t changing dramatically.
