Standards Development
The Need for IEEE 802.15.4g
• In 2008 there were no wireless communications
standards for Peer to Peer Field Area Networks
• There were a number of proprietary Field Area
Network solutions; many were based on a
common technology
A standard was needed - IEEE802.15.4g
Copyright © 2015 Wi-SUN™ Alliance
7
Standards Development
IEEE 802.15.4g - Scope
• Focus on Smart Utility Network Communication
• Optimise for Large Scale outdoor Wireless Mesh
Networks – Field Area Network
• To take proven technology and create a standard
to allow interoperable products and address a
global market.

Standards Development
IEEE 802.15.4g - Timeline
• May / July 2008 – Interest Group Meetings
• September 2008 – Study Group formed
• November 2008 – PAR was approved
• January 2009 – First meeting of 802.15 TG4g
• March 2010 – First Letter Ballot
• August 2011 – First Sponsor Ballot
• March 2012 – Approved by IEEE Standards Board

11
Supported Applications
• There are a wide range of requirements across different
Smart Utility Applications, e.g. :
– Advanced Metering Infrastructure
– Demand/Response
– Distribution Automation
– Smart City – e.g. Street Lighting
– Low power Meter reading – e.g. Gas Metering
– Home Energy Management Systems
• These applications have a variety of communication
requirements
• Communication “profiles” support these application needs
Copyright © 2015 Wi-SUN™ Alliance
12
Standards Development
Risks
• Many different stakeholders
• Process results in standards which include many
options and features
• Standards can be too generic to implement –
– more options increases the problems in achieving
interoperability
• A great start, but …
Copyright © 2015 Wi-SUN™ Alliance
13
What was still needed?
• Specifying the communications functionality for each
Smart Utility Network Application
– Options add complexity and make interoperability
more difficult to verify.
• A testing and certification process
– IEEE802 writes standards, it does not describe testing
• An Industry Alliance provides the forum
– to focus on commercial applications
– to define testing and certification

Certification Program Levels
• PHY Certification
– Test Physical layer behavior in situ on communications
module
– Appropriate for Silicon Vendors, Module Vendors, System
Vendors
• Profile Certification
– Test full communications profile behavior in final product
– Appropriate for Module Vendors, System Vendors, System
Integrators
Copyright © 2015 Wi-SUN™ Alliance
39
Certification Testing Strategy
• Two Part Testing:
– Conformance Testing – assessing Device Under Test for
conformance to the specification using specialized test
equipment
– Interoperability Testing – assessing Device Under Test for
interoperability with reference implementations known as
Certified Test Bed Unit (CTBU)
• All testing is conducted by a Wi-SUN appointed Independent Test
Laboratory – Third Party Testing
• Device Under Test must pass all relevant tests to be eligible for
certification
Copyright © 2015 Wi-SUN™ Alliance
40
Certification Testing Strategy
•
•
During Test and Certification Program Development
– Quality assessment and improvement of
• Profile Technical Specification
• Test Specification
• Test Equipment and test tools
• Member company products
– Wi-SUN Alliance uses formal reporting strategy for assessing status
Steady State
– Venue for Member Companies to assess the readiness of their products for
deployment.
– Continual Assessment of Test and Certification Program
– Impact of Profile Technical Specification Changes on test plan and backward
compatibility

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.
