Power line coupler adapted for use with multiple service panels
First Claim
1. A system for interfacing a power line communications (PLC)-enabled communication device with a power network residing in a building, wherein the power network includes a first service panel and a second service panel, and wherein the first service panel and the second service panel are interconnected and include at least one common phase power line of the power network, the system comprising:
- a coupling circuit that includes a primary port coupled to the communication device, a first secondary port coupled to the first service panel, and a second secondary port coupled to the second service panel, wherein the coupling circuit is configured to receive a high-frequency broadband communication signal from the communication device, split the communication signal into two portions, inject a first portion into the common phase power line at the first service panel and inject a second portion into the common phase power line at the second service panel.

Abstract
Systems and methods for interfacing a power line communications (PLC)-enabled communication device in a building with a power network are disclosed. In various embodiments, a system can include a specially-configured coupler that enables a common PLC communications signal to be injected into the same power phase line of the power network, but at different service panels.
