1. A wireless communications relay device, comprising:

  • a receiver for detecting transmissions from other such devices;

    a transmitter for transmitting signals at a first power level for normal traffic, and a higher, inhibition level, in order that its transmissions may be detected by other such devices over a wider area than its normal operating range; and

    a control means for selecting a channel and a transmission power on which the transmitter will operate, the control means being arranged to inhibit the transmitter from selecting channels detected by the receiver when the transmitter is operating at the inhibition level to prevent co-channel interference between transmitters of wireless communications relay devices that are not in the normal operating range of each other but whose normal operating ranges overlap.
