  • Information and control communication over power lines
    Patent number: 6281784
    Abstract: Power line installation wires which carry electricity to energize devices connected to the wires can also be used simultaneously to carry other electrical signals that convey information or control between devices connected to the wires. With regard to the disclosed power line communication system and method and related components and processes, each device to be connected to an electric power line installation can be uniquely identified (referred to as the device's electronic genetics) in such a manner that practical applications are not limited as to the number of devices connected to, or as to complexity of information or control effected by communications over, the wires of the power line installation. With its unique identity, any such device can be connected to any power line installation to communicate with any other such device connected to that installation so long as the identity information and linked operational files are within the system of devices connected to the particular installation.
