ABSTRACT:
A method of distributing wide band data using a neutral-to-ground circuit within an electrical wiring installation includes modifying a load center with an interface module which interfaces to the neutral-to-ground circuit and configuring the interface module to compensate for varying impedance within the neutral-to-ground circuit to improve data transmission characteristics. Multiple embodiments are included within the method for compensation of varying impedance including channel sounding, spectral waterfilling, and communications using spread spectrum techniques, for example, frequency hopping and direct sequencing techniques.
