  • Apparatus and method for implementing digital communications on a power line
    Patent number: 6278357
    Abstract: An apparatus to establish bi-directional digital communication over a power line network includes a signal launching circuit to impose a digital communication signal onto a power signal carried by a power line network and thereby form a digital communication power signal at a first point in the power line network. The signal launching circuit is configured to position a pulse of the digital communication signal at any phase location of each half cycle of the power signal. A receiver reads the digital communication power signal at a second point in the power line network. A signal processor is connected to the receiver to recover the digital communication signal from the digital communication power signal.
