GSM Networks

GSM is the only mobile technology providing truly global coverage with more than 2.6 billion users worldwide.

Nortel's GSM network solution includes GSM access products that offer a microcellular solution designed to fill any hot spot and significantly increase the subscriber base. The GSM/GPRS/EDGE core solutions give wireless operators circuit- and packet-based options. Nortel also improves operators' solutions for GSM and UMTS through our recently announced Next Generation All-IP Voice Core Products (MSC Server, HLR, and Media Gateway) and our high capacity Packet Core (SGSN and GGSN) products. The Nortel OAM&P solutions feature a set of products designed to support centralized maintenance and management of GSM, GPRS, and EDGE networks. GSM-R is a communications system for railway networks based on GSM technologies.

GSM, because of its global scale and technology maturity, continues to be the most cost-effective platform for providing voice and data services. However, GSM/EDGE technology is still evolving and remains the most economical solution to meet the market needs in terms of voice and data traffic while preparing for 4G.

Nortel has worked with more than 100 operators in over 65 countries to implement cost-effective, high-performance GSM/GPRS/EDGE networks. Built on our GSM access and core network solutions, our networks are characterized by near-wireline voice quality, unparalleled security, unequalled radio performance and leading-edge wireless voice and data capabilities.

Nortel's GSM portfolio is based on a brand new range of products that deliver superior performance, address operators' challenges in terms of OPEX and also paves the way to 4G in an optimized manner.

The Nortel GSM Access Network solutions are based on the strength of our Base Transceiver Stations (BTS) and Base Station Controllers (BSC). Nortel's GSM access products offer a wide range of solutions designed to provide nationwide coverage and to fill any hot spot and significantly increase the subscriber base.

Nortel recently launched new All-IP Core Network products that support the GSM/UMTS MSC and HLR, as well as our fourth generation of Media Gateway processor for state-of-the-art, high-quality wireless voice. Similarly, Nortel continues innovating in our packet core network products, with new releases of software in 2007 and early 2008 to support higher capacities in an optimized network solution. We use our significant experience in the core network to design and engineer networks with high levels of reliability and scalability for voice and data services, and Nortel complements this strategy by integrating intelligence, allowing operators to offer security and corporate services to end users, as well as providing advanced billing models for content and services for postpaid and prepaid users.

The Nortel GSM Operations, Administration, Maintenance and Provisioning (OAM&P) solutions feature a set of products designed to support centralized maintenance and management of GSM, GPRS, and EDGE networks.

GSM-R is the wireless communication standard for railway networks. It has been developed under European Union sponsorship to assist railways in achieving their goals of network interoperability, reduced operational costs, improved safety at higher speeds, and delivery of new services for the benefit of passengers and employees. More and more countries are adopting GSM-R technology worldwide.
