Wireless Control That Simply Works IEEE 802.15.4g - Need
• Focus on Smart Utility Network Communication
• Primary Application Area –Field/Neighbourhood Area Network
• Optimise for Mesh Networks
• There were already many existing large scale outdoor wireless
mesh networks for Utility communications.
– Primarily North America where spectrum rules are favourable
• Existing networks and solutions were proprietary, but many
were based on a common technology
• The industry needed interoperability:
– Cost: good for customers
– Longevity: AMI installations are not consumer electronics,
installation lifetimes of at least a decade are needed
• Requirement to harmonize, maybe improve, but not re-invent.
• To take proven technology and create a standard to allow
interoperable products and address global market.

Wireless Control That Simply Works TG4g-SUN PAR: Scope
This Standard defines an amendment to IEEE 802.15.4. It addresses principally outdoor Low
Data Rate Wireless Smart Metering Utility Network requirements. It defines an alternate
PHY and only those MAC modifications needed to support its implementation.
Specifically, the amendment supports all of the following:
• Operation in any of the regionally available license exempt frequency bands, such as
700MHz to 1GHz, and the 2.4 GHz band.
• Data rate of at least 40 kbits per second but not more than 1000 kbits per second
• Achieve the optimal energy efficient link margin given the environmental conditions
encountered in Smart Metering deployments.
• Principally outdoor communications
• PHY frame sizes up to a minimum of 1500 octets
• Simultaneous operation for at least 3 co-located orthogonal networks
• Connectivity to at least one thousand direct neighbors characteristic of dense urban
deployment
• Provides mechanisms that enable coexistence with other systems in the same band(s)
including IEEE 802.11, 802.15 and 802.16 systems

Wireless Control That Simply Works Wi-SUN Alliance in Europe
• European Utilities have focussed on PLC and GPRS,
• OK for meter reading of consumption data but not ideal for applications requiring more frequent reads or peer – peer communications.
• Lack of available ISM spectrum and duty cycle restrictions has made Wireless mesh less attractive
Wireless Control That Simply Works Wi-SUN Alliance in Europe
What’s changed? • 870 – 876 MHz is becoming available in many European
Countries (Q1 2014?) with liberalised operating parameters, including reasonable Transmit Power limits and operating duty cycles
• Where license exempt (i.e. free) spectrum is available, radio mesh has won over 80% of the awards (the Americas, AUS/NZ)
• Radio mesh can deliver 100-300 kbps, allowing for applications beyond simple meter reading.
• Reading the meter multiple times a day and treating it as a sensor, not just a billing register, enables Smart Grids and Smart Cities.
• Enables connection of devices other than meters to the network

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.”
