19.0          Sprint PCS Service
       All Sprint PCS services are delivered on an all-digital nationwide network using
one of the most advanced commercially available wireless technologies (i.e. CDMA
– Code Division Multiple Access) as the single, ubiquitous transmission standard.
CDMA is a digital technology that allows multiple calls to share a single channel by
distributing a call’s signal across a range of available frequencies and assigning them
a unique code that the receiver uses for call identification. This combination of
“spread-spectrum” transmission and separation of calls by codes makes efficient use
of Sprint PCS’ full frequency spectrum. Some competitors must maintain
“patchwork” networks with a mix of analog and digital technologies, but Sprint PCS
offers CDMA digital technology throughout its entire system. The result is the ability
to offer more than 10 times the network capacity that analog transmission standards
can offer for cellular systems. This allows callers to get through more often and is
vital for the support of wireless data applications as they evolve. CDMA technology
also intrinsically provides enhanced privacy and security that leads to a significant
reduction in cloning and eavesdropping. Therefore, the government can be confident
of private and secure wireless voice conversations and data transmissions. All of this
allows Sprint to provide the Government with the same reliable, secure, scalable, and
cost-effective service in virtually all the nation’s major metropolitan areas including
more than 4,000 cities and communities across the country.


19.1          Basic Service Description
       Most wireless networks today are very similar in structure, but where they are
similar in structure, they differ greatly in functionality. This makes it important to
realize that not all wireless offerings are equally comparable in terms of their current
and future capabilities. When building a wireless network, a carrier is faced with a
decision on what and how it will implement two key technologies: the transmission

standard and the over-the-air interface. The transmission standard describes the
method for sending information over a physical wireless medium, and the over-the-
air interface determines how many users can access the system at any given time by
managing the resources available for those users. This is what determines a network’s
capacity, communication quality, and support for future voice and data services.

       There are several transmission standards on the market today which are based on
3 common over-the-air interface types: Frequency Division Multiple Access
(FDMA), Time Division Multiple Access (TDMA), and Code Division Multiple
Access (CDMA). In the corresponding figures below, each block of color indicates a
separate call.

      FDMA – Considered the first generation of wireless communications, the
       available spectrum is divided into frequency bands or channels. Each channel is
       assigned to an individual user to make a call. Once the connection is established,
       the channel will be occupied for the duration of the call. FDMA is the underlying
       technology for traditional analog cellular systems such as Advanced Mobile
       Phone System (AMPS) and Total Access Communication System (TACS).
       Figure 1.B.19-1 illustrates FDMA’s use of spectrum.

Figure 1.B.19-1                           FDMA’s use of Spectrum
      TDMA – Considered the second generation of wireless communications. Similarly
       to FDMA, the available spectrum is divided into channels. However, it is a digital
       technology that, analogous to the concept of Time-Division Multiplexing assigns
       a specific time slot within a channel for users to transmit their message. Each call
       has full use of the channel during its time slot, but in the meantime must wait
       until its turn in the rotation to transmit again. The receiving equipment receives
       each piece of the segmented call and reassembles them into a continuous stream
       of speech. Because this rotation occurs very quickly (i.e. each time slot is only a
       fraction of a second) the parties typically don’t notice a delay or interruption in
       the call. Some transmission standards based on TDMA technology are IS-136 and
       Global System for Mobile Communications (GSM). Figure 1.B.19-2 illustrates
       TDMA’s use of spectrum.

      CDMA (IS-95b) – Both a transmission standard and an air-interface technology,
       CDMA is considered a 2.5 generation technology (2.5G). In contrast to FDMA
       and TDMA, CDMA places callers onto one channel that utilizes the entire
       frequency spectrum available and uses a unique digital code to distinguish
       individual calls. Each call’s signal is then distributed across the entire range of
       available frequencies using spread-spectrum techniques. Figure 1.B.19-3
       illustrates CDMA’s use of spectrum.

       Without further inspection, the benefits of CDMA over the other technologies are
readily apparent. FDMA made very inefficient use of spectrum by dedicating
frequencies to individual calls. Since two links are necessary for proper
communication (i.e. forward and reverse link or sometimes referred to as the
downlink and the uplink respectively) normal voice communications usually
involving a speaker and a listener meant that only half of the resources allocated for
the call was being used at a time. Furthermore, considering natural silences and gaps
occur within typical speech on an average of 45-50% of the time, spectrum efficiency
is further reduced to 25%. To combat the capacity constraints of FDMA, TDMA was
developed. By allocating time slots, more users could utilize the spectrum at any
given time. This meant increased capacity, but the inherent delays of rotating time
slots posed potentially significant reductions in throughput of data transmissions.
TDMA systems also transmit a high data rate on a narrow-frequency channel,
increasing the chances for interference and reducing the quality of both voice and
data calls.

       CDMA was developed to obtain both increased capacity and overall transmission
quality. The combination of spread-spectrum transmission and separation of calls by
codes provides several inherent features. Figure 1.B.19-4 illustrates the effects of
spread-spectrum technology.




                    Figure 1.B.19-4                            Effects of Spread-Spectrum Technology
       CDMA makes efficient use of the full allocation of spectrum. As a result, CDMA
can offer increased network capacity of at least 8 times over AMPS technology in a
typical network. This increased capacity can be exploited by allocating fewer calls to
a given coverage area than TDMA or FDMA systems would require. Deploying
fewer resources can lower the cost structure for the carrier and make it faster, simpler
and more cost-effective to build and expand a PCS network.

       CDMA also provides greater air-interface security. Technologies using a narrow
bandwidth of frequencies such as TDMA are more susceptible to interference
because they tend to be easier to isolate and detect within a given frequency
spectrum. However, since spread-spectrum technology utilizes a greater range of
frequencies, it would require less information density per frequency to transmit the
same signals. In effect, calls are made to resemble low level noise which camouflages
them to interceptors. Therefore, in order for a potential eavesdropper to tap into a
wireless transmission using CDMA spread-spectrum technology, they must be able to

isolate the different segmented portions of the signal over a wide frequency range.
The perpetrator would then need to decipher the codes assigned to each call out of
more than 4 trillion possibilities while the call is active. In effect, the coding scheme
used by CDMA effectively encrypts the information before transmission unlike the
“clear channel” nature of FDMA and TDMA. Unfortunately, obtaining one code will
only gain access to half of the call since each call is composed of both a downlink
and an uplink with each link given its own code. In addition, the eavesdropper would
also need to know where the user is located, know the user's electronic serial number,
and the exact moment when the user is making the call. These requirements are a
tough combination for even a determined intruder to meet and virtually eliminates the
possibility of casual eavesdropping or cloning.


Network Architecture

       In 1994, the FCC made available the right to use and develop communication
systems now called PCS or digital wireless. Auctions were held to allow companies
the opportunities to purchase rights to provide digital service in areas across the
United States. The FCC divided the spectrum of frequencies into several bands and
auctioned rights to each band. Six bands A-F were made available. Bands A-C made
up the Major Trading Areas (MTAs) and bands D-F made up the Basic Trading Areas
(BTAs).

       By purchasing the largest amount of spectrum within both the Major Trading
Areas (MTAs) and Basic Trading Areas (BTAs), Sprint PCS was able to make
CDMA the single ubiquitous technology throughout its network and therefore
position itself to be a preeminent full-service provider of wireless communications.

       When Sprint PCS set out to build a wireless network, they also took great care in
ensuring that its network would be scalable and reliable. This is accomplished in 2
ways.

1. Open Network Architecture – Rather than relying on a single vendor, Sprint PCS
       has implemented a design that allows multiple vendors to develop new products
       and services resulting in the most advanced and cost-efficient wireless
       technology. New features are more quickly implemented due to the inherent
       compatibility of the Open Network Architecture.
2. Intelligent Network – New features and services are often necessary in an
       emerging network that is also constantly evolving. Sprint PCS’ Intelligent
       Network provides flexibility and scalability during this process. When
       improvement to network features or services are necessary, having the flexibility
       of an Intelligent Network allows for immediate network convergence. New
       features and services can be activated via the web immediately upon
       confirmation. Features and services can also be customized based on individual
       profiles. Sprint PCS’ Intelligent Network will also provide the capability to meet
       future demands for wireless communication services such as the ability to
       implement custom dial plans and wireless PBX features.

       Figure 1.B.19-5 is a basic depiction of Sprint PCS’ wireless network.

       There are 5 components that make up the Sprint PCS network.

1. External Networks - Mobile users can be reached through the Sprint network (e.g.
       other Sprint users) or from the Public Switched Telephone Network (e.g. analog
       POTS).
2. Mobile Switching Center – The MSC performs the switching functions that allow
       mobile subscribers to reach external networks.
3. Base Station Controller – The BSC is responsible for the routing of calls to the
       appropriate Base Transceiver Station. It also performs the vocoding process that
       involves analyzing speech and compressing it to digital signals so that bandwidth
       can be preserved.
4. Base Transceiver Station – Sometimes referred to simply as a base station, this is
       where the transmission standard and air-interface type is employed. It performs
       all of the necessary functions for sending and receiving wireless transmissions.
       Two connections are necessary for a call to take place: Forward and backward

       link or often referred to as the downlink and uplink respectively. Base
       Transceiver Stations contain the heart of a wireless network. Each Base
       Transceiver Station creates a broadcast or coverage area called a cell.
5. Subscriber Unit – Any wireless enabled end-user device.

Frequency Reuse

       One of the major challenges a wireless carrier faces when deploying a wireless
network is frequency planning. Frequency Planning describes the method in which
cell sites are distributed to meet the demands of the user population. Traditionally in
cellular networks, frequency planning was extremely complex. Since calls were
distinguished by the particular frequency they were designated, the location of cell
sites had to be designed so that there were no adjacencies between cells using the
same allocated spectrum. Consequences of doing so could mean cross talk,
interference, static, or lack of service all together. This is complicated by the fact that
the area in which cell sites cover are not a predictable shape or size. Frequency
planning continues to be a hurdle even in digital wireless networks today. However,
by using CDMA technology, Sprint PCS was able to design their network without the
burdens of conventional frequency planning issues. Since CDMA uses the entire
range of allocated spectrum and separates individual calls by assigning them a unique
digital code, the design of cell site locations becomes almost trivial. Cell sites could
overlap with their adjacencies or even occupy multiple base stations without the
consequences of interference or loss of service. Not only does this simplify the build-
out and expansion of the network; it also allows Sprint PCS to design the most cost-
effective and efficient wireless network today.

Soft Call Handoff

       Poor frequency planning can also lead to the most common reason for a dropped
call: a failed handoff. In addition to actual call drops, the handoff can be preceded
and followed by long periods of poor link quality, experienced as fading, static or
other distortion.

       A handoff occurs when a wireless user moves from the coverage area of one cell
to another. In Figure 1.B.19-6 below, a handoff would occur as the user moved from
Cell 3 to Cell2. During this process, a cellular or PCS system would automatically
transfer the call from the old base station covering Cell 3 to a new base station that
offers a stronger signal that covers Cell 2.




                                Figure 1.B.19-6                            Handoff Situation Example
       Conventional cellular and most PCS technologies use a “hard” handoff method.
In this method, the system must break the connection to the old base station before
making a connection to the new base station. In a hard handoff, the system does not
confirm that the new connection has been made to the new base station before
dropping the connection to the old base station.

       PCS systems based on CDMA use a “soft” handoff technique that verifies the
new connection before dropping the old one. This is done by exploiting the mutipath
properties of radio signals (i.e. Decoding multiple versions of the same signal that
arrive as a result of refraction and traversing of multiple paths). This is demonstrated
below in Figure 1.B.19-7.




Figure 1.B.19-7                            Demonstration of the Multipath Properties of Radio Waves
       The different “versions” of the original signal are combined to create a stronger,
clearer one to the user. This is the same process used to create a “soft” handoff. As a
subscriber is moving from one cell to another, it will begin to process its receiving
signal from the base stations of both cells. A successful handoff will be made only
after it has completely moved into the new cell, is operating off the signal from the
new base station, and is no longer receiving a signal from the old base station. Only
then will it discontinue its connection with the old base station. In fact, a subscriber
unit can even establish multiple, simultaneous links with several nearby base stations
with overlapping coverage areas until it identifies the base station with the strongest
signal. All cells involved with links to the wireless user participate in the handoff
communication and share the signal during the transition. All of this result in

smoother and more reliable handoffs, with fewer dropped calls, less static and more
consistent quality throughout a call.


Network Survivability

       Sprint PCS understands that being a pre-eminent service provider is just as
important as delivering those services under the most dire of circumstances. Three
key elements of the Sprint PCS Network provide stability in the event of a disaster:

1. X
2. X
3.      X

Disaster Recovery

       The Sprint PCS General Disaster Recovery Plan is based on the four phases of
disaster preparedness as defined by the Federal Emergency Management Agency
(FEMA).

1. Mitigation – Activities actually eliminating or reducing the chance of a disaster’s
       occurrence or its effects. For example, the reinforcing of towers to reduce the
       effects of high winds or the addition of larger fuel tanks on generators which
       increases running times and reduces refueling.
2. Preparedness – Planning how to respond and working to increase resources
       available to effectively respond to all situations. Preparedness plans should be
       designed not only to maintain network connectivity, but should also strive to
       minimize dangers to employees. This phase will also include the training of
       personnel and the testing of recovery plans to enhance response capabilities and
       to familiarize personnel with plan objectives.

3. Response – The activity occurring during and immediately following an
       emergency. During this phase Corporate Response Teams (CRT) may be
       dispatched to the affected area to assist in the coordination of recovery efforts.
4. Recovery – The final phase of the Disaster Preparedness Planning process.
       Recovery continues until all systems return to normal or near normal. However,
       the recovery phase from a disaster may go on for months until operations are at
       the same pre-disaster level.

General Disaster Recovery Plan to its specific needs and vulnerabilities of location
and environment as requested. The Risk Assessment Survey includes not only the
market’s location vulnerabilities to natural disasters (severe weather, earthquakes,
fire, etc.) but also physical location and entry procedures, security measures, backup
power availability, and site directions.

       Physical security measures such as monitoring systems, intrusion detection
devices, alarms, fire detection and fire suppression are in place to protect personnel,
sites and facilities where appropriate.

       Our disaster recovery program includes proactive steps such as developing
emergency contact lists including telephone numbers, mutual aid agreements, local
vendor information and state and local official contact numbers. Sprint PCS does not
wait to coordinate access requirements with state and local emergency management
officials and local civil authorities. Rather, Sprint PCS disaster representatives in
each market contacts state and local emergency management officials to ensure
access to equipment locations during post disaster recovery operations. In situations
where local authorities are hindering access to Sprint PCS facilities, the National
Coordinating Center has established a process for escalating the matter on behalf of
Sprint PCS.

19.2          Coverage
       Sprint PCS serves the majority of major metropolitan markets in the United States
and over 4,000 cities and communities throughout all 50 states, Guam, Puerto Rico,
and the U.S. Virgin Islands. Sprint PCS also has roaming agreements that allow users
to make and receive calls while off the Sprint PCS Network (additional charges will
apply) in nearly every area of the United States where wireless service is available.
Automatic CDMA domestic roaming agreements are available throughout many
areas of the United States and Canada. In mobile phone coverage areas where Sprint
PCS does not have roaming agreements available, calls can be completed using
standard commercial practices. Offshore Termination is also available to make
international long distance calls with Sprint PCS service. However, International
Termination will only be offered when it is specified on the service order.
International termination charges are not included in the basic service offering. In

addition, surcharges for international termination to devices covered under Calling
Party Pays (CPP) are not covered under the international termination charges. CPP
surcharges are controlled by the foreign carriers and are passed through to the
Government. These CPP surcharges are in addition to any international termination
charges. Only domestic coverage is offered by default for all service plans.

       At this time, Sprint PCS does not support coverage to pay-per-call services such
as those accessible via 900 and 976 numbers.


Service Limitations (PCS ONLY)

       This section is subordinate to FAR Clause 52. 249-02 Termination for
Convenience of the Government (Fixed-Price) (SEP 1966) and FAR Clause 52.249-
08 Default (Fixed-Price Supply and Services (APR 1984).

       Sprint’s sole liability for any direct loss or damage arising under this Agreement
is limited to, with respect to Services, a prorated portion of the applicable ”MRC”
and, with respect to Products, a refund of the Price of the affected Products.

       The parties acknowledge that coverage and quality of Services can be affected by
atmospheric, geographic, and topographic conditions and other conditions beyond
Sprint’s control including the failure of other service providers. The parties also
acknowledge that interruption and unavailability of services due to coverage,
capacity, product failure or other limitations may occur in the transmission or
attempted transmission of wireless services. In consideration of the foregoing and
except as specifically provided in this Agreement, the parties agree that Sprint will
not be liable for any loss of service, lack of coverage or quality of service, or product
failure regardless of cause. Further, because Sprint does not provide such
information, Sprint is not liable for the accuracy or reliability of any information

       Under no circumstances is Sprint liable for any incidental, consequential, punitive
or special damages of any nature whatsoever arising out of or in connection with

connection with the services), including, without limitation, loss of business, or cost
of replacement products and services.

       Disclaimer of warranties. Sprint makes no express representations or warranties
regarding the services or products and disclaims any implied warranties, including
any warranties of merchantability or fitness for a particular purpose or use or non-
infringement. Sprint does not authorize anyone to make a warranty of any kind on
Sprint’s behalf and the Government should not rely on any such statement. Sprint is
not the manufacturer of any products or equipment and, except as otherwise expressly
provided in writing by Sprint, statements regarding any products or equipment should
not be interpreted as a warranty by Sprint. Products come with a limited
manufacturer’s warranty directly to the end user. This section is subject to FAR Part
52.212-4 Contract Terms and Conditions – Commercial Items (MAY 1999) to the
extent applicable to PCS.


19.3          End-to-end Communication Function (EECF)
       Sprint PCS' wireless service offering will provide a complete end-to-end
connection to the Government. In order to do this, Sprint PCS will supply end-to-end
communication functions to the Government. The two basic categories of wireless
end-to-end communication functions supported by Sprint PCS are the following:

       Single-band Sprint PCS End-to-end communication functions allow the user to
make and receive calls on digital networks only. This means that calls can be made

from anywhere on the digital Sprint PCS Nationwide Network. Calls can also be
made to anywhere on or off the network. In some areas, digital roaming is available
(additional charges will apply). Single-band end-to-end communication functions
function best for those users who stay mostly within a single metropolitan area. Users
desiring a single-band EECF should indicate so in the Feature column of the PCS
service request.

       Dual-band Sprint PCS End-to-end communication functions allow the user to
make and receive calls on both digital and cellular networks. This means that calls
can be made from anywhere on the Sprint PCS Nationwide Network or in other
analog/digital cellular areas where roaming agreements are in place (additional
charges will apply). Dual-band end-to-end communication functions function best for
those users who will be moving between metropolitan areas. Users desiring a dual-
band EECF should indicate so in the Feature column of the PCS service request.

       Sprint offers several EECFs that are compatible with TTY devices. When
ordering, the user must select the EECF category that contains a TTY compatible
device and also indicate TTY in the feature column of the PCS service request.

       Sprint PCS will assign a Mobile Identification Number (MIN) to each end-to-end
communication function provided to the Government for use with their Sprint PCS
service.

       If the end-to-end communication function becomes non-functional due to a
manufacturing defect, the customer is entitled to repair or replacement of the
defective unit at no additional charge during the first year of purchase. Please refer to
Section 9 of the management volume for further information on trouble reporting.

Link calls can be made to one person at a time or to several people simultaneously.
This feature can be added to any EECF that is classified as a Ready Link EECF.

       A caller enters the two-way mode by pressing the Ready Link button. The caller
will then hear a tone indicating that the call has begun setting up. Call setup times
range from 7-10 seconds, but is sometimes shorter. This delay is just in the call set
up. Once the call is setup, and the connection is established the conversation flows
very quickly and easily.

       Ready Link offers unlimited nationwide Group Calling to up to 5 other PCS
Ready Link users. Therefore you can have a total of 6 Ready Link users in a group
calling setting.

Agency has deployed a Sprint-provided or a competitor’s WAN solution, Sprint PCS
DLWWS provides the flexibility to use wireless connectivity for mobile workers,
remote locations or as backup to their wireline access.

Sprint DLWWS provides a high level of security by providing a direct connection
between Sprint’s CDMA network and the Agency’s WAN solution. Whether they
are connecting to Sprint MPLS VPN, Sprint Link Frame Relay, or a CPE-based VPN
through IPSec, the Agency’s traffic will not touch the public internet.

Sprint DLWWS allows, using a Sprint-certified CDMA modem, Agencies to leverage
the Sprint PCS network to connect fixed and transportable locations, or serve as
backup to wireline access. Data Link Wireless WAN is ideal for low bandwidth
applications such as Point of sale devices, sales kiosks, ATM machines, and
monitoring devices. Wireless WAN is an ideal alternative or backup to 56k Frame
Relay, ISDN, DSL or Broadband.

Wireless WAN Components
Sprint DLWWS can be used as a primary WAN service replacing existing lower
speed wireline facilities or as a backup failover service to augment existing wireline
services.

Wireless WAN components include:
    Sprint Data Link – provides the wireless CDMA transport service, security
       and connectivity to the customer’s host network.
    Sprint CPE Operations – provisions and installs the wireless modems as
       well as providing technical break/fix on-site support.
    Sprint MNS – provides pro-active managed services and tier 2 support for
       Wireless WAN customers.
    Wireless Modems – provide the physical interface between the customer’s
       LAN equipment (ie router) and the Sprint wireless network.

Agencies choosing Sprint PCS Data Link have options for connectivity from the
Sprint Wireless network to their enterprise network:

             IPSec Virtual Private Network (VPN): With this connectivity option,
              Agencies can connect their corporate network to the PCS Network by
              tunneling through the SprintLink network. Sprint uses the IPSec Protocol to
              encapsulate the data in secure IP packets for safe transport across the IP
              network. The CPE and VPN does not have to be Sprint-managed.

             Sprint Frame Relay PVC: With this connectivity option, Agencies can connect
              their corporate network to the PCS Network by using a Permanent Virtual
              Circuit (PVC) that leverages either the Sprint Global Frame Relay or
              SprintLink Frame Relay network. This option is best suited for Agencies who
              require the advanced security of a private network and have policies against
              using the Internet to transmit data.
             MPLS: With this connectivity option, Agencies can connect their corporate
              network to the PCS Network through an MPLS VPN on the Sprint Global
              MPLS network.
             Sprint DLWWS is currently not supported on the Sprint peerless IP network.
