The G3-Alliance is a consortium created in 2011 to standardize and promote powerline and hybrid RF technology globally. The technology, standardized under ITU-T G.9903, uses the existing powerline infrastructure as well as radio for cost-effective data communication.

The main applications of the technology include smart metering, smart grids, street lighting, smart cities, home automation systems, railway control systems and many other industrial applications.

Today, the G3-Alliance counts nearly 100 members that are international key stakeholders of the smart grid ecosystem, including utilities, semiconductor companies, equipment manufacturers and industrial companies. Together, they support, promote and implement the G3 technology and established an industrial certification program to enable the interoperability of devices from different manufacturers.

Over 80 million products have already been deployed in more than 30 countries around the world.
