Nokia Siemens Networks pilots 4 calls in GSM radio Timeslot

, , , ,

Nokia Siemens Networks has carried four calls in one GSM radio timeslot for the first time ever on 21 January of this year. The network equipment manufacturer successfully completed a drive test for the Orthogonal Sub Channel (OSC) that doubles the voice capacity of GSM radio network. The OSC innovation is an important addition to Nokia Siemens Networks' offering of sustainable and green products and solutions. With OSC, operators can gain more capacity from the same base station hardware, meaning fewer base station sites are needed in network roll outs 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.
