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.

Claims

1. A repeater for receiving a signal on an inbound channel and transmitting said signal on an outbound channel, comprising:

a first receiver means for receiving said signal on said inbound channel,

determination means for determining quality characteristic of said signal when received on said inbound channel,

a second receiver means for monitoring presence of a channel activity on said outbound channel,

controller means responsive to presence of said channel activity on said outbound channel and said quality characteristic of said signal for generating a control signal;

transmitter means responsive to said control signal for transmitting said signal on said outbound channel.

2. The repeater of claim 1, wherein said contoller provides a delay before generating said control signal, said delay corresponding to said quality characteristic.
