Abstract
The system comprises a wireless transceiver with a processor for measuring RSSI in received signals. The processor analyzes fade duration or fade frequency in the received signals to determine if the transceiver is moving. If the transceiver is moving, then the processor can send a command to disable a fixed wireless terminal in one embodiment. In another embodiment, if the transceiver is not moving, then the processor can send a command to place a GPS receiver into a power conservation mode.
