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-theair 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.

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.

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.

Figure 1.B.19-3

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.

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 buildout and expansion of the network; it also allows Sprint PCS to design the most costeffective 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. Network Management Control X Disaster Recovery Teams X Individual Market Readiness Risk Assessment Surveys are performed to assist in the mitigation and preparedness process of the development of unique Disaster Recovery Plans. A Disaster Preparedness Planning Team assists each market in tailoring the Sprint PCS 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. X X 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 52.24908 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.

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 dualband 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.

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. X 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.
