Alcatel-Lucent announced a Dynamic Power Save (DPS) enhancement to its GSM/EDGE mobile networking portfolio that can reduce power consumption by up to 27 percent, offering significant energy and cost savings for mobile operators. The power reductions were demonstrated during January field trial this year with China Mobile in the country’s Jiangsu province. On average, a 24 percent power saving has been achieved.
Alcatel-Lucent said its Dynamic Power Save capability involves switching off the power amplifier in GSM transceivers. It enables the base station to monitor traffic activity on the network and when there is no information to transmit, even for very short periods of time, the amplifier is switched off. This process offers substantial cost savings at night when calling volumes are naturally lower, but also, because of the sensitivity of the monitoring techniques, considerable power savings are available during busy times as well. These saving are obtained without any increases in call blocking or reductions in packet data throughput so the service quality remains high. Because this is a software upgrade, this enhancement can be installed on all Alcatel-Lucent multi-standard base stations deployed since 1999, some 500,000 stations.
