6 IEEE g - 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. 6

7 TG4g-SUN PAR: Scope This Standard defines an amendment to IEEE 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 , and systems 7

8 TG4g-SUN PAR: Purpose To provide a global standard that facilitates very large scale process control applications such as the utility smart-grid network. To supports large, geographically diverse networks with minimal infrastructure. Smart Metering Utility Networks can potentially contain millions of fixed endpoints. To provide The communication range, robustness, and coexistence characteristics required for this class of application. 8

13 What was missing? Identifying and specifying the communications functionality needed across the range of Smart Utility Applications A testing and certification process IEEE802 writes standards, it does not address testing 13

14 The Applications There are a wide range of requirements across different Smart Utility Applications, e.g. : Advanced Metering Infrastructure Demand/Response Distribution Automation Low power Meter reading e.g. Gas Metering These applications lead to a variety of communication requirements IEEE g PHY implementations and appropriate upper layers can support these application needs 14

15 Need for Wi-SUN Alliance IEEE g PHY amendment which specifically addresses wireless Smart Utility Networks was approved by IEEE SA Standards Board on March 29, 2012 Significant interest from product developers and RF IC manufacturers Industry recognition of benefits of interoperable products Wi-SUN Alliance was formed to focus specifically on Wireless Smart Utility Networks 15

27 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

28 Wi-SUN Alliance in Europe What s changed? 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 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

35 Current Status of collaboration TEPCO adopts Wi-SUN specification for Wireless Smart Utility Network. Tokyo, Japan. October 3, 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. 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 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. 35 Slide 35
