An RF repeater arrangement for use in a wireless telephone system has a number of handset interface parts, each provided with a transmit section for transmitting a signal to a wireless telephone handset, a receive section for receiving an off-air signal from the wireless handset and an energy detector for detecting the energy level of the received off-air signal and providing a control signal corresponding to such energy level. The control signal is employed for inhibiting the transmit section when the energy level of the received off-air signal is below a predetermined value. Thus, each handset interface part can determine when a channel is occupied and avoid transmission on that channel, so that only the geographic area around the occupied handset is subject to interference from the occupied channel.
