The ZigBee Alliance, a global ecosystem of organisations creating wireless solutions for use in energy management, commercial and consumer applications, have introduced the completed 920IP, an update to ZigBee IP, an open, global standard for an IPv6-based full wireless mesh networking solution to control low power devices.
Alliance members, primarily OKI, NEC Engineering, Ad-Sol Nissin, Texas Instruments and Skyley Networks, have been developing 920IP in response to Japan's Ministry of Internal Affairs and Communications (MIC) designation of 920 MHz for use in home energy management systems (HEMS) and the Ministry of Economy, Trade and Industry (METI) endorsement of ECHONET Lite as a smart home standard. The ZigBee Alliance has entered into agreements with Telecommunications Technology Committee (TTC) and ECHONET Consortium to support the development efforts.
"In 2013, TTC signed a MoU with ZigBee Alliance and enacted the TTC standard JJ-300.10 and TTC technical report TR-1043. Now we welcome the completion of global standardisation of the 920IP by ZigBee Alliance. Adding this new option may lead wider deployment of energy management solutions and expansion of the market in Japan," said Yoichi Maeda, CEO and SVP of TTC.
920IP provides specific support for ECHONET Lite and the requirements of Japanese HEMS. It enhances the IEEE 802.15.4 standard by adding network and security layers and an application framework. The standard offers a cost-effective and energy-efficient wireless multi-hop mesh network based on standard Internet protocols, such as 6LoWPAN, IPv6, RPL, and UDP. It also supports security and authentication features such TLS-PSK, EAP and PANA and link layer frame security based on the AES-128-CCM algorithm.
"ECHONET Lite is used as a standard of application interface of HEMS in Japan," said Morio Hirahara, representative Director of the ECHONET Consortium. "(Since we have) IP with the 920MHz option by the ZigBee Alliance as one of the recommended protocols for ECHONET Lite, higher interoperability and wider deployment will be expected."
The Alliance will soon announce an extension of the ZigBee Certified programme to certify end products for ECHONET Lite devices using 920IP. The programme is being developed in cooperation with the ECHONET Consortium and will insure both conformance to the standards and interoperability between products from different manufacturers.
Register here for a free online ZigBee webinar about the new standard. The webinar will be conducted in Japanese on July 31, at 6 pm JST.
