Abstract
A point-to-point communications system () for transmitting messages from any location (A) within a power distribution system or network () to any other location (B) within the network. A transceiver () at the one location includes a transmitter (X) that impresses a waveform (W) on a waveform (W) propagated by the network to supply power throughout the network. The transmitter is a resonant transmitter that includes a reactive load () which is selectively connected to and disconnected from the power distribution network. A controller () controls operation of the transmitter to connect and disconnect the reactive load from the network so to impress on the propagated waveform a dampened sinusoidal waveform whose characteristics represent information conveyed over the power distribution system. A receiver (Yn) at the other location receives and demodulates the dampened sinusoidal waveform to extract therefrom the information being conveyed by it.
