Nortel Smart Power Management (SPM) software enables network operators to switch off radio network equipment when there is no caller traffic being processed by the system. This can provide up to a 33 per cent reduction in energy savings by reducing Base Transceiver Station (BTS) power consumption. This feature, combined with other enhancements made to Nortel's GSM technology, make today's Nortel GSM portfolio up to 50 per cent more energy efficient than it was five years ago.
The SPM feature is available as a simple software upgrade to Nortel GSM radio base station equipment. Other enhancements recently made by Nortel to increase the overall energy efficiency of its GSM portfolio include hardware improvements to increase power amplification efficiencies, and optimisation of BTS cooling systems.
Nortel is said to offer a smooth migration from legacy to IP networking through IP upgrade modules that can be installed in existing BTS and Base Station Controller (BSC) cabinets. Migrating to IP networking can provide up to a 40 per cent reduction in transmission costs for GSM operators while simultaneously preparing the network for LTE.
Power reductions that can be achieved through this solution were demonstrated in a trial conducted in February 2009 with China Mobile Communications Corporation (CMCC).
