A base transceiver for use in radio communication with one or more distant transceiver units is operable to apply a downlink interference detection mode wherein (i) the base transceiver periodically generates and sends a test signal to the one or more distant transceiver units;(ii) the base transceiver senses whether or not a response signal is sent by a distant transceiver in response to receipt of the test signal; and (ii) if no response signal is detected the base transceiver generates an interference detection signal. A method of operation using the base transceiver and a transceiver for use as the distant transceiver are also described. <IMAGE> |
