Wi-Sun Alliance Finishes Verification of Communications Specification for Echonet-Lite-based Wireless Smart Utility Network Products
Aug 29, 2013 (Close-Up Media via COMTEX) --
The Wi-Sun Alliance, an ecosystem of organizations creating interoperable wireless solutions for use in energy management, smart-utility network applications, announced completion of Wi-Sun Echonet-Lite specification and is now available for product development.
According to a release, the specification provides for fully interoperable, multiple vendor implementations.
The alliance reported that in January, Wi-Sun Alliance published Wi-Sun profiles for Echonet Lite version 1, a standard communication interface for Echonet Lite and the interface was selected as a TTC (Telecommunication Technology Committee) standard, TTC JJ300.10. The newly published specification (Wi-SUN profile for Echonet Lite version 2) adds new features that ensure the interoperability and network deployment, standardize pairing of devices and simplifying installation and maintenance for consumers and custom installers alike. Specifically, the new specification includes an encryption and an authentication process between smart meter and home energy management system (HEMS) and between HEMS and home electrical appliance. These features have a significant impact on operational and device costs to service providers and quality of service to the society.
Further, the Wi-Sun Echonet Lite specification and test plan supports enhanced functionality in devices such as door locks, smoke sensors, window blinds, air-conditioning, refrigerators and support for additional devices including smart appliances and electrical measurement devices. The standard incorporates new features resulting from collaboration between Wi-Sun Alliance and the Echonet initiative, a Japanese consortium of more than 100 companies, which will benefit consumers by integrating new devices and raising consumer awareness of energy usage without necessarily connecting to an electric utility.
"The Wi-Sun Specification for Echonet Lite 2.0 is a major step forward in creating an open and fully interoperable wireless Home Energy Management platform," said Phil Beecher, Chairman of the Wi-Sun Alliance. "For Service Operators and CE companies, Wi-Sun Echonet Lite will provide a technology standard that removes much of the complexity from planning and deploying advanced home services and reduces the amount of energy they consume."
"The Wi-Sun Specification for Echonet Lite 2.0 is the most robust, reliable and scalable low power wireless standard for Home Energy Management Systems, and the technology of choice for world-leading service providers, installers and retailers," said Hiroshi Harada, NICT, Wi-Sun Alliance board co-chair and chair of the Echonet WG."
"We are very happy to contribute as Technical Editor to the Echonet WG," said Tamiya Ochiai, Chief Specialist, Toshiba Corp. "We believe the Wi-SUN Specification for Echonet Lite 2.0 delivers a standard that can make every home a smarter, safer and more energy efficient environment for consumers and families."
The Echonet standards are globally applicable, international communication standards for linking home appliances made by different manufacturers.
