Abstract

A power line communication system that contains a signal coupling device containing an input to receive a communication signal from a communication network; and an output to transmit the communications signal to a high frequency signal transducing means. Each of the high frequency signal transducing means is couplable to a power line in a manner that allows the high frequency communication signal (e.g. 10MHz to 30 MHz) to be transmitted (for example, by electromagnetic coupling) without directly connecting to the standard low voltage (e.g. the 110V or 220V) normal AC electrical power lines.
