Abstract:
1. System, for transmitting and receiving signals over residential electrical cables comprising at least one active wire, one neutral wire and one ground wire, said system comprising: at least two power line modems, each one of said at least two power line modems coupling a respective electrical device with a respective electrical socket, each said respective electrical socket being coupled with said residential electrical cables, each one of said at least two power line modems comprising: a processor; a plurality of transmitters, coupled with said processor, for transmitting said signals; and at least one receiver, coupled with said processor, for receiving said signals; wherein at least two of said wires form at least one receive wire pair, wherein at least two of said wires form at least one transmit wire pair, wherein each one of said plurality of transmitters is respectively coupled with a different one of said at least one transmit wire pair; wherein each one of said plurality of transmitters is assigned a respective set of carrier waves over the respectively coupled transmit wire pair; wherein said processor determines a frequency carrier wave for said signals when said signals are transmitted, wherein a given one of said plurality of transmitters transmits said signals if said frequency carrier wave is in said respective set of carrier waves of said given one of said plurality of transmitters.
