ABSTRACT:
A repeater for a wide area coverage multiple repeater system (100) includes a receiver (220) and a transceiver (230). The receiver (220) receives a received signal from a portable or mobile communication unit (130) on an inbound channel. The received signal is routed to a receive signal strength indicator (RSSI), a bit error rate (BER) detector, or a similar devices for differentiating a received signal quality characteristic. The transceiver (230) includes a transmitter (232) for repeating the received signal on an outboard channel and a receiver (234) for monitoring presence of an outboard channel activity. A controller (260) enables the transmitter (232) to retransmit the received signal, based on the received signal quality characteristic, and in absence of the outboard channel activity.
