Abstract: The present invention provides an FM Orthogonal Frequency Division Multiplexing (OFDM) modulation process that enable high-speed data communications over any transmission media and networks. The process is implemented with a modem device modulator and demodulator that provides communication with several other modem devices along any communication media that uses an FM OFDM modulation technique, a physical transmission medium such as power lines, or wireless (air), or cable, or twisted pairs communication media.

Abstract: A communication apparatus for high-speed data transmission over power line networks comprises a head-end unit which provides a single logical entry point into the communication network, an infrastructure of physical power line cables, one or more client-end units which communicate with the head-end unit, and one or more hybrid units which simultaneously acts as a head-end unit for another physical sub-network of the power line communication network and functions as a client-end unit of another physical sub-network of the power line communication network.
