摘要：T An apparatus (10) for transmitting a communication signal, across one ormore pre-existing frequency channels or bands that carry a transmission signal,comprises a memory for storing at least one pre-existing frequency channel or bandtogether with information relating to a strength of the transmission signal carried by theat least one pre-existing frequency channel or band. A controller (24) generates acommunication signal to be transmitted across at least one of the channels or bands at astrength sufficient to over-broadcast the transmission signal carried. A mixer (26) receiveseach of the communication signals generated by the controller (24) and combines saidcommunication 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 signalcarried by the at least one pre-existing frequency channel.
