Abstract

A system for extending the Smart Meter'"'"'s range to connect to Home Area Networks for energy monitoring and demand response in a variety of locations. The system has a data concentrator with a wireless communicating module configured to transmit and receive information at one or more first frequencies ranging up to 2.4 GHz, and a power-line module configured to transmit and receive information at one or more frequencies ranging from about 100 to 30 MHz. The data concentrator receives power information from one or more Smart Meters and convert the wireless signal to a power-line carrier signal over the existing all three phases of the AC wiring. The system also includes a wireless and power-line carrier bridge that converts the power-line carrier signal back to a wireless signal to connect to various Home Area Network (HAN) devices such as programmable communicating thermostats (PCTs), smart appliances and in-home displays (IHDs).
