Power line communication system and method of operating the same
First Claim
1. A communications system for providing communications via a first and second power line that are communicatively coupled to each other at a coupling location, the system comprising:
- a first communications device communicatively coupled to the first MV power line at a first location, wherein the first location is a first distance from the coupling location, and wherein said first communications device transmits data over MV power lines a first communications distance;
a second communications device communicatively coupled to the second MV power line at a second location, wherein the second location is a second distance from the coupling location;
wherein the sum of the first distance and the second distance is greater than the first communications distance; and
wherein the first distance is less than the first communications distance.

Abstract
The present invention provides communications via multiple power lines that are communicatively coupled to each other at a coupling location, which for example may be at a substation. In one embodiment, the system may comprise a first communications device communicatively coupled to a first power line at a first location, wherein the first location is a first distance from the coupling location. A second communications device may be communicatively coupled to a second power line at a second location, wherein the second location is a second distance from the coupling location. The devices may be backhaul points, bypass devices, or other PLC network elements. The first communications device transmits data over power lines a first communications distance. The locations are selected so that sum of the first distance and second distance is greater than the first communications distance even if the first distance is less than the first communications distance.
