GSM Radio Access Networks

Nokia Siemens Networks’ association with GSM technology has continued since the advent of the cellular mobile telephony, beginning from the world's first GSM call in 1991, continuing with the world's first EDGE call in 2003 to the world’s first Downlink Dual Carrier (EDGE Evolution) call in 2008. Today, we are one of the undisputed leaders in GSM/EDGE with over 320 GSM and over 220 EDGE radio network customers in over 135 countries, serving over 2.1B subscribers.

Today, around 1.5 Million new GSM users are added to the GSM networks every day. As a result, new networks are built and the existing networks are expanded to new geographical areas, partially driven by lowering end user tariffs. One of the biggest challenges for operators is to upgrade and optimize the network infrastructure so as to cope with the huge increase in both voice and data traffic while maintaining cost efficiency and network quality.

Nokia Siemens Networks is committed to deliver more efficient networks, provide unmatched end user experience and reduce environmental impact with its unique and innovative GSM products, software features and site solutions.

The mobile ecosystem is changing. Since 3G data boom is spreading onto GSM networks, the GSM networks need to be prepared for new business opportunities. Smart device friendly GSM networks are able to support more new devices, higher number of end users along with increased traffic and signaling load. This will lead to higher quality service experience, reduced network infrastructure costs and potential increase in revenue.

Network infrastructure typically accounts for nearly 80% of the operator‘s energy consumption. With expansion of networks into areas with no electricity grid, operators across the world are stepping up to reduce energy consumption and minimize its impact on the environment. Our comprehensive portfolio of products, features and site solutions enables operators to maximize energy efficiency, generate energy savings and reduce CO2 emissions.

Typically, GSM network modernization return of investment in 1 to 2 years. Our best selling Flexi Base Station, Flexi Base Station Controller TCSM3i and unmatched software features can help define whether we can be good or excellent in GSM business.

Originally implemented to 3G WCDMA networks, the Wideband AMR voice codices are now also available for GSM networks with easy software upgrade. With the speech quality moving up by one scale, the subscriber growth, network usage as well as retention can be maximized. In addition, the 3G subscribers can enjoy HD voice more often, when implemented for GSM networks.

IP/Ethernet is already used in 3G and LTE networks. Up to 50% bandwidth can be saved with packet transmission. Our IP/Ethernet solutions cover Abis, A and Gb interfaces.

Our unique OSC and DFCA Application Software features minimize the cost of the radio network voice capacity upgrade or modernization.
