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.

25. A communication system for communicating information over a power line grid comprising:

a first head-end unit connected at a distant end to the power line grid; and

one or more first hybrid units connected to the power line grid at a customer premises, said one or more hybrid units including;

a first client-end unit adapted to communicating with the first head end unit, and

a second head-end unit adapted to communicating with the first client-end unit and with one or more second client-end units.
