The license covers the operation of Global System for Mobile Communications (GSM), General Packet Radio Service (GPRS) and Enhanced Data Rates for Global Evolution (EDGE) technology for the network. [14] Telenor Pakistan has signed two deals with mobile infrastructure contractors for different areas of the network: Nokia has signed a three-year deal to build and operate a GSM / GPRS / EDGE network to cover the central and Northern Punjab region (phase one), centered around Lahore. Siemens have signed a deal to build a GSM / GPRS / EDGE network to cover the southern areas of Pakistan, centered around Islamabad. Further enhancements in data capacity over the core GPRS / GSM network will be provided in both networks with the installation of Enhanced Data for Global (GSM) Evolution technology.

This component of the two systems will be installed after the initial roll-outs and will allow the subscribers to have the use of advanced mobile services such as downloading video and music clips, full multimedia messaging, high-speed color Internet access and email on the move. Nortel Networks will upgrade Ufone's existing wireless systems and supply GSM / GPRS core network and radio access equipment, including Mobile Switching Center, Home Location Register (HLR) and advanced Base Transceiver Stations (BTS). A key component of the Ufone expansion will be Nortel Networks BTS 12000, designed to deliver additional capacity within a GSM / GPRS network while positioning operators to drive lower costs and to offer advanced wireless services based on third generation (3G) EDGE (Enhanced Data for GSM Evolution) technology. The expansion will also include Nortel Networks Passport Packet Voice Gateway (PVG) for migration of TDM voice trunking to a packet-based infrastructure. 7. Benefits As highlighted previously the need to reduce business risk and make the best use of existing resources is of paramount importance within today's business environment.

7.1. Financial GSM based networks have become the standard within the cellular landscape. As EDGE is a GSM based technology and provides an enhancement for GPRS at a little additional cost it is considered the best way in which to capitalize on existing resources. [1] 7.1.1. Radio Access Network In most cases GPRS enabled base stations and BSC's can be simply upgraded to EDGE by way of relatively low-cost software and hardware upgrades, which will pro-long the life cycle of the deployed RAN elements. 7.1.2. Core Network For GPRS enhancement, there is very little modification to be completed within a GPRS enabled core network, thus enhancing the sunk core network investment.

7.1.3. Antenna Sites There is no requirement for additional antenna sites when deploying EDGE. Assuming high quality linear amplifiers with high RF output power are used within the BTS, the coverage pattern will be the same as the existing GPRS deployment, so protecting existing site investment. 7.1.4. Spectrum Utilization EDGE triples the GPRS data capacity whilst using the existing GSM spectrum and offers up to three times the GPRS data rate to the end user. EDGE is spectrally the most efficient radio technology for data applications requiring up to 100Kb / s throughput (compared to CDMA and WCDMA), and only WCDMA is spectrally better for higher throughputs.

7.1.5. Applications GPRS enabled applications and services will generally not require any additional investment to become EDGE compatible. This is also valid for known WCDMA applications. Although the financial benefits of EDGE can be attributed to individual network elements as outlined above, one of the main business drivers is that EDGE forms an essential part of the overall GSM evolution towards a seamless multi-radio GSM / GPRS / EDGE / WCDMA network.
