The Wi-SUN Alliance has completed verification of its physical layer conformance and interoperability test specifications for wireless smart utility network devices using IEEE802.15.4g.

The alliance says this the final step in developing a certification process by which products may qualify to use the Wi-SUN PHY logo, assuring interoperable deployment for utility networks.

During the alliance's fourth interoperability testing event, held at TUV Rheinland labs in Pleasanton, Calif., vendors and test equipment manufacturers executed a full suite of tests soon to be published by the alliance. Conformance tests assure that standards are implemented correctly, while interoperability tests confirm that products from different vendors communicate with each other correctly. Both are necessary to validate implementations of standards, the alliance says.

In addition, the alliance says its members validated the applicability of the Wi-SUN PHY test specifications as the foundation for key areas of utility networks, including field area networks and home area networks.  Participants performed further testing of the Wi-SUN field area network and Wi-SUN ECHONET profiles, both of which incorporate the Wi-SUN PHY and higher-level protocols as part of their specifications.
