Standards Development
IEEE 802.15.4g - Need
• In 2008 there were no wireless communications standards for
Peer to Peer Field Area Networks
• A standard was needed : IEEE802.15.4g
• Focus on Smart Utility Network Communication
• Primary Application Area –Field/Neighbourhood Area Network
• Optimise for Mesh Networks
• Large scale outdoor wireless mesh networks for Utility
communications.
• Existing networks and solutions were proprietary, but many
were based on a common technology
• To take proven technology and create a standard to allow
interoperable products and address global market.

11 May 29th 2014 Copyright © 2014 Wi-SUN™ Alliance
Wireless Control That Simply Works What was still needed?
• Specifying the communications
functionality for the variety of Smart
Utility Network Applications
– Options add complexity and make
interoperability more difficult to verify.
• A testing and certification process – IEEE802 writes standards, it does not
address testing
12 May 29th 2014 Copyright © 2014 Wi-SUN™ Alliance
Wireless Control That Simply Works The Applications
• There are a wide range of requirements across
different Smart Utility Applications, e.g. :
– Home Energy Management Systems
– Advanced Metering Infrastructure
– Demand/Response
– Distribution Automation
– Low power Meter reading – e.g. Gas Metering
– Smart City – e.g. Street Lighting
• These applications have a variety of communication
requirements
• Wi-SUN “profiles” support these application needs

TEPCO adopts Wi-SUN specification for Wireless Smart Utility Network.
Tokyo, Japan. – October 3, 2013 - The Wi-SUN® Alliance, a global ecosystem of organizations creating
interoperable wireless solutions for use in energy management, smart-utility network applications, today
announced that the Wi-SUN Alliance specification for the Wireless protocol between Smart Meter and Home
Energy Management Systems has been selected by TEPCO (Tokyo Electric Power Company Inc.
http://www.tepco.co.jp/en/index-e.html) for its Wireless B route. TEPCO will deploy 27 million smart meters over
the next 10 years.
The Wi-SUN ECHONET-Lite specification version 2 was made available for product development in August 2013.
The specification provides for fully interoperable, multiple vendor implementations helping to simplify technology
selection, installation and maintenance for consumers and custom installers alike. It includes an authentication
and encryption process between smart meter and home energy management system (HEMS), and between
HEMS and home electrical appliances.
"The Wi-SUN Specification 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.
"This marks a major success for Wi-SUN Alliance," said Phil Beecher, Chairman, "Our members have developed
broad global specifications supported by a robust, open, testing and certification process. We have also worked
extensively with other stakeholders to map these specifications to regional needs. We are honored that TEPCO,
one of the world’s largest utilities, has provided this validation of the value of our collaborative, global, process.”

NEW INDUSTRY COLLABORATION TO IMPROVE SMART GRID SYSTEM INTEROPERABILITY
OpenADR™ Alliance and Wi-SUN® Alliance Form Strategic Relationship to Advance Energy Efficiency
MORGAN HILL, Calif., TOYKO, Japan Feb., 25. 2014: The OpenADR Alliance and WI-SUN Alliance today
announced a liaison agreement to more quickly accelerate the rollout of energy efficient program offerings. The
two organizations will work together to enable interoperability between Smart Utility Networks and utility demand
response programs based on the OpenADR specification.
“Both the Wi-SUN Alliance and the OpenADR Alliance are finding growing acceptance of their respective
specifications globally,” said Barry Haaser, managing director, OpenADR Alliance. “It is important to enable
interoperability between the two specifications to provide seamless connectivity between Wi-SUN based smart-
utility networks and OpenADR based automated demand response programs.”
“This agreement will help energy providers deploy smart utility networks and automated demand response
programs cost effectively and with confidence,” said Phil Beecher, chairman, Wi-SUN Alliance. “The two industry
standards are highly complementary, offering Utility companies more flexibility in their demand response and
energy management program offerings.”
OpenADR and Wi-SUN will collaborate with their respective members and will offer incentives to members to
encourage joint participation in complementary activities.
