Interoperable wireless technology association the Wi-SUN Alliance has unveiled a new specification for wifi connectivity in advanced metering infrastructure (AMI), distribution automation and smart cities that can be applied in most regions of the world.
The non-for-profit industry group released this week a complete version of its technical profile specification for field area network communications.
The specification allows smart utility networks to talk to enterprises, service providers and municipalities by enabling interoperable, multi-service and secure IPv6 communications over an IEEE 802.15.4g-based wireless mesh network.
Regions supported by this specification, now and in the near future, include North America, Japan, Brazil, Australia, Asia Pacific, India, Europe, the Middle East and South Africa, said Wi-SUN Alliance in a statement.
Commitment to interoperability
Commenting on the new release, Phil Beecher, chair of the Wi-SUN Alliance, said the specification shows the commitment of major industry contributors to collaborate on a truly interoperable specification.
While Raj Vaswani, CTO, Silver Spring Networks and co-chairman of the board for the Wi-SUN Alliance, said the "specification creates the basis for the certification program that will deliver on that promise, and thus drive additional growth of smart networks worldwide" .
Industry experts, such as Kip Compton, VP of IoT Systems and Software, Cisco Systems, said: "This is a significant milestone in building a truly interoperable specification for RF Mesh networks. It demonstrates a true commitment by a number of the major vendors developing RF Mesh solutions using IEEE and IETF IPv6 standards based specifications."
Wireless connectivity details
The specification includes:
- 802.15.4g physical layer congruent with the existing Wi-SUN Alliance PHY Certification Program
- Frequency hopping, network discovery/join and protocol dispatch
- IPv6 protocol suite, including 6LoWPAN, address management, routing using RPL, unicast and multicast forwarding
- Standards-based multi-layer security specification encompassing authentication, authorization, encryption, etc.
