Problems solved by technology

However, repeating the signal, for example in an overhead power line environment, is problematic because the regenerated signal interferes with the original signal and reduces the overall bandwidth
[0009] Second, such systems are inherently unreliable
Their ability to communicate may be disrupted when power lines fail, such as due to line failure, device failure, weather / lightning faults, overloaded transformers, blown fuses, or other causes

Abstract

A system, method and computer program product provides for power line communications (PLC) over electric power lines includes a device mountable near an electrical distribution transformer (DT) to provide a high speed interface and communicates with one or multiple access devices, which provide low speed interfaces for analog signals or digital signals over RS 232, RS 485, optical, wireless and Ethernet. The device transmits data to / from these access devices over the electric lines to other repeaters over one or more wires of an electrical line or over multiple lines, and serves to strengthen and improve signal quality. Upon detecting a wire or line is having problems carrying data, the data is sent over other wires, and upon power line failures, wireless backup to mobile / GSM and WiMax networks is utilized. The device permits utilities and others to read electric meters, monitor the power quality of the distribution grid and detect power losses / failures / outages.

Description

technical field [0001] This application claims the title "Reliable, Long-Haul Data Communications over Power Lines for Meter Reading and Other Communications Services," filed August 8, 2008. Long-distance data communications) to the benefit of US Provisional Patent Application No. 61 / 087,444. technical field [0002] Exemplary embodiments relate generally to communications, and more particularly to communications over power systems. Background technique [0003] Power line communication (PLC) refers to a system for carrying data on conductors, typically for electrical power transmission. Alternative terms for PLC include power line carrier, mains communication, power line telecommunications (PLT) and power line networking (PLN). [0004] In these systems, electrical energy may be transmitted over high voltage transmission lines, distributed over medium voltage, and typically used within buildings at low voltage. Power line communication can also be applied at each stage...
