TEPCO Adopts Wi-SUN Specification for Wireless Smart Utility Network

The Wi-SUN Alliance specification for the wireless protocol between smart meter and home energy management systems has been selected by Tokyo's TEPCO for its wireless B route. TEPCO will deploy 27 million smart meters over the next 10 years.

The Wi-SUN ECHONET-Lite specification version 2 was made available for product development in August 2013. The specification provides for fully interoperable, multiple vendor implementations helping to simplify technology selection, installation and maintenance for consumers and custom installers alike. It includes an authentication and encryption process between smart meter and home energy management system (HEMS), and between HEMS and home electrical appliances.
