Wi-SUN Alliance conducts interoperability tests among smart utility network IEEE 802.15.4g devices

Tokyo, Japan and San Jose, CA, U.S.A. — (METERING.COM) — September 11, 2012 – The Wi-SUN Alliance has completed successful interoperability tests of smart utility network devices compliant with the IEEE 802.15.4g standard.

Wi-SUN has developed an interoperability test suite for IEEE 802.15.4g and related regional regulatory requirements. IEEE 802.15.4g is a global standard harmonizing the physical layer of a number of historically deployed wireless systems, and standardizing power levels, data rates, modulations and other technical properties, as well as frequency bands appropriately matched to the large scale, outdoor environment of smart utility networks.

Products were from companies including Analog Devices, Agilent Technologies, Anritsu, EDIC Systems, Murata Manufacturing, NICT, Procubed, Renesas Electronics, Satori Electric, and Silver Spring Networks. Testing of these platforms demonstrated interoperability in sub-GHz frequency bands appropriate for Japan, North America, Australia/New Zealand, Latin America, and other regional markets.

Participants also took the opportunity to demonstrate interoperability of their media access control (MAC) implementations, including options specified in the IEEE 802.15.4e-2012 amendment.

This testing marks the first step in providing a rigorous testing program, and follows the development by the Alliance of an NIST SGIP compliant testing process for a range of products including radio ICs, modules and end products.

The Alliance will shortly announce the appointment of independent test laboratories to provide test services for IEEE 802.15.4g capable products, and in the coming months will begin certification testing of end-user products based on Wi-SUN defined profiles for this key standard.

“The Wi-SUN Alliance has worked hard over the past few months developing a testing strategy to ensure interoperability of smart utility network products,” said Phil Beecher, chairman of the Alliance. “We have focused on developing an open and participatory testing and certification process and are working to ensure the rapid and successful approval of Wi-SUN products from member companies.”

The Wi-SUN Alliance will continue to develop and make widely available a certification program for testing end products, such as smart meters and other smart utility network devices. In the initial phase, the Alliance will require members to test their end product devices at one of the appointed test houses and to participate in an Alliance sponsored interoperability testing event to confirm interoperability with other similar products in a Wi-SUN capable network. A device must successfully complete both steps to meet the requirements for Wi-SUN certification.
