Abstract
A portable wireless transceiver (104) includes a receiver (206) for monitoring transmissions from neighboring transceivers (106A and 106B) to select a transceiver to use for communications. The portable wireless transceiver (104) further has a motion detector (204) for determining whether or not the portable wireless transceiver (104) is moving. If the portable wireless transceiver (104) is determined to not be moving, a processor (202) alters a schedule for monitoring of neighboring transceivers (106A and 106B) so that the monitoring is performed less frequently, thereby reducing power consumption by the portable wireless transceiver (104).
