Power Line Communication System and Method
First Claim
1. A power line communications system for providing communications for one or more user devices via one or more low voltage power lines, the system comprising:
- a first communications device comprising a coaxial cable interface, and a backhaul link interface in communication with said coaxial cable interface and configured to be communicate over a backhaul link;
a second communications device comprising a first modem and a first low voltage (LV) power line interface in communications with said first modem, where said first modem is communicatively coupled to said coaxial cable interface of said first communication device via a coaxial cable;
wherein said first modem is configured to communicate over the coaxial cable via communications that comprise a substantially compatible Data Over Cable System Interface Specification (DOCSIS) protocol; and
wherein said second communications device is in communication with one or more of the user devices via a first low voltage power line communicatively coupled to said first LV power line interface.

Abstract
A power line communications system for providing communications for one or more user devices via one or more low voltage power line is provided. In one embodiment the system includes a plurality of first communication devices, each comprising a first modem configured to communicate using a DOCSIS protocol, and a first low voltage power line interface configured to communicate with a plurality of user devices via a low voltage power line. A second communication device includes a backhaul link interface configured to communicate over a backhaul link and a downstream interface configured to communicate with the first modems of the plurality of first communication devices. The plurality of first communication devices transmit upstream data signals in a first frequency band and receive downstream data signals in a second frequency band different from the first frequency band.
