Doubling the GSM Voice Capacity with Standard Handsets

For the first time in the world, four calls have been carried in one GSM radio timeslot. This significant step in GSM evolution path was taken today by Nokia Siemens Networks who successfully completed a drive test for the Orthogonal Sub Channel (OSC), that doubles the voice capacity of GSM radio network.This successful demonstration opens up a profitable growth path for operators, evolving their networks to a new level of efficiency with minimized CAPEX and OPEX. This is made possible by a software upgrade to existing Flexi EDGE Base Station and Base Station Controller. OSC is fully interoperable with existing handsets, so it promises immediate cost saving for operators, said Prashant Agnihotri, Head of GSM/EDGE product management, Nokia Siemens Networks.

With OSC, operators can gain more capacity from the same base station hardware, meaning fewer base station sites are needed in network rollouts and capacity extensions, which in turn saves energy and decreases the CO2 emissions.The OSC demonstration was conducted as a drive test using four handsets sharing only one radio timeslot and without compromising the call quality. The demonstration with existing commercially available GSM handsets was the first one of its kind in the world, strengthening Nokia Siemens Networks’ leadership in GSM/EDGE radio technology.
