Abstract
System, for transmitting and receiving signals over residential electrical cables includes at least one active wire, one neutral wire and one ground wire. The system includes at least two power line modems, each one of the two power line modems including a processor, transmitters and at least one receiver, transmitters and the receiver being coupled with the processor, for respectively transmitting and receiving the signals. At least two of the wires form at least one receive wire pair and at least two of the wires form at least one transmit wire pair. Each one of the transmitters defines a respective carrier wave range over the transmit wire pair, the processor determining a frequency carrier wave for the signals when the signals are transmitted. A given one of the transmitters transmits the signals if the frequency carrier wave is in the carrier wave range of the given one of the transmitters.
