Benefits of Wireless Mesh for

Field Area Networks

• Flexibility

• Reliability

• Resilience

• Adaptive and Self Healing

• Low Operational Expenditure

• High Data Rates

• Bidirectional Data

• Can be battery powered (Gas and Water metering)

• Good for AMI and DA



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.


Wireless Control That Simply Works 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


Wireless Control That Simply Works Result – IEEE 802.15.4g features

• Backward compatibility with installed base of 10’s millions of

meters.

• High performance

• High data rate

• Low latency

• High reliability

• Highly scalable networks

• Low cost

– Low complexity, mature technology, so low R&D costs to recover

• Global and Proven

• Great flexibility


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


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

Certification

Program Elements

• To enable the test and certification services, TCC has

developed or mobilized the following resources and

entities:

– Testing Strategy

– Test Specifications

– Test Laboratory

– Test Equipment

– Certified Test Bed Unit (CTBU)

– Interoperability Testing Events

35


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

36


Certification Program

Elements

• Test laboratory

– TCC works with Wi-SUN-approved test laboratory to deliver

third party testing

• Test equipment

– TCC works with test equipment vendors to provide test

harness for conformance testing

• Certified test bed unit

– TCC works with product vendor to develop certified test

bed units (CTBU) to facilitate the third party interoperability

testing

– CTBU is a reference implementation against which a

device under test shall conduct interoperability testing

38


Interoperability

Testing Events

Two distinct phases:

• 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.
