High-Speed and Long-Range Power Line Communication

G3-PLC is a power line communication standard that facilitates high-speed, highly-reliable, long-range communication over the existing power line grid. With two-way communications networks based on the G3-PLC standard, operators of electricity networks will be able to intelligently monitor and control grid issues. This includes the implementation of variable tariff plans and real-time monitoring of electricity consumption. In addition,this new communication standard benefits consumers with the advantage of being able to regularly check their electricity consumption in real time and to actively reduce their consumption accordingly.

The ability to cross transformers cuts infrastructure costs and with its support of IPv6, G3-PLC will support power line communications in the future.

Certification of G3-PLC products, such as home energy management systems, will guarantee the correct implementation of the G3-PLC specifications as well as the interoperability and performance of those products tested.
