摘要： T An apparatus (10) for transmitting a communication signal, across one or more pre-existing frequency channels or bands that carry a transmission signal, comprises a memory for storing at least one pre-existing frequency channel or band together with information relating to a strength of the transmission signal carried by the at least one pre-existing frequency channel or band. A controller (24) generates a communication signal to be transmitted across at least one of the channels or bands at a strength sufficient to over-broadcast the transmission signal carried. A mixer (26) receives each of the communication signals generated by the controller (24) and combines said communication signals into a combined mixed communication signal (15). A transmitter (16) transmits the combined mixed communication signal (15) across the at least one pre-existing frequency channels or bands either to replace or add the transmission signal carried by the at least one pre-existing frequency channel.
