2Wi-Fi: The Intelligent Choice for the Smart Grid

Wi-Fi today - An unrivaled success

10% of the worlds population uses Wi-Fi

About two billion cumulative shipments

Double-digit growth year over year strongmomentum continues

Wi-Fi is now ubiquitous in home, enterprise,industry, education and governmentenvironments

Consumers love Wi-Fi*

*7 out of 10 users would rather give up chocolate than Wi-Fi (Millward-Brown, 2008)

73% of university students say Wi-Fi helps them get better grades (Kelton Research,2008)

Wi-Fi Alliance activities underway toaddress Smart Grid uses of Wi-Fi technology

Smart Grid Task Group in Wi-Fi Alliance provides a forum for industrycollaboration

Evaluate needs for additional testing/certification programs

Provide industry input to government agencies and regulators (US andworldwide) regarding use of Wi-Fi in Smart Grid

Chair: Mark Thompson (Aclara), Vice-Chair: Phil Beecher (Gainspan)

Wi-Fi Alliance also a participating member of NISTs Smart GridInteroperability Panel (SGIP)

Wi-Fi Alliance offers expertise in Wi-Fi technology for multiple SmartGrid applications (Home, Neighborhood, WAN) and operating a best-in-class interoperability certification program for 10+ years

Wi-Fi in the Neighborhood Area Network

Wi-Fi is highly suitable for large outdoornetworks to connect smart meters to aneighborhood area network.

Wi-Fi has already been deployed in

city-scale networks for both wirelessaccess and backhaul.

Wi-Fi technology supports many

different configurations point-to-point,

point-to-multipoint, distributed mesh.

IEEE 802.11s, which standardizes Mesh over 802.11, will drive industry

coalescence around self-healing large-scale Wi-Fi networks.

Wi-Fi: The worlds preferred HAN technology

Loved by consumers and specified by broadband service providers

Wi-Fi is at the heart of the smart home, connecting computers, entertainment

devices, appliances, and Smart Grid devices on a single technology

Whole-home coverage and industry-

supported easy setup protocols

Versatile technology: multiple

interoperable versions ranging fromlow-power to high-performance

Resilient to interference andcoexists well with other technologies

Government-grade security mechanismsrequired for certification of all devices

Some benefits of Wi-Fi in the Smart Grid

Ubiquity

Range

Bandwidth

Power Consumption

Application Scope

> 1 billion devices. Home, enterprise, metronetworks. Wide range of device types.

Whole house coverage. Kilometer outdoor point-to-point. 802.11n MIMO.

Interoperable, auto-rate capability from megabitto 600 megabit

WMM Power Save. New low-power chipssupporting >10 year battery life.

Native IP support. Wide range of interoperable

power/performance profiles. Hugecommercial investment in Wi-Fi applicationdevelopment .


11/18


Wi-Fi Features for Smart Grid: Ubiquity

Wi-Fi is already the dominant HAN within US homes

Wi-Fi is already deployed as a neighborhood network in many metropolitanareas

Wi-Fi is already in a wide variety of devices: computers, consumer electronics,

smart phones, handhelds, industrial control, Wi-Fi is best positioned to be the only communications technology that is in common

among all devices

Wi-Fi is being integrated into key Smart Grid components: meters, appliances,thermostats,


12/18


Wi-Fi Features for Smart Grid: Range

Wi-Fi can provide whole-house coverage in most US homes without the need foradditional routers or mesh implementations

Greater range minimizes the issue of problematic appliance locations

Auto-rate capability can adjust signalling modulation downwards to ensure best

performance at a given range

802.11n MIMO provides best range/robustness


13/18


Wi-Fi Features for Smart Grid: Bandwidth

For Smart Grid, Wi-Fi can support low-bandwidth devices/applications costeffectively and can interoperably support higher bandwidth applications as

well

Wi-Fi products support rates ranging from megabit to 100s of megabits -- interoperably

Future Smart Grid monitoring and control applications may require greater datarates than those anticipated today

Auto-rate capability ensures that the modulation technique and data rate areoptimized for given range and signal environment

Higher data rates means both support of new applications and support of moretotal traffic


14/18


Wi-Fi Features for Smart Grid: Low PowerConsumption

This is important, for example, in integrated metering scenarios(water/gas/electric)

802.11 MAC protocol incorporates effective power saving mechanisms

Wi-Fi Alliances WMM Power Save certification program

New lower power, lower complexity Wi-Fi chipsets are now able to achieve > 10

year battery life


15/18


Wi-Fi Features for Smart Grid: Application Scope

Wi-Fi is best suited to support the full range of future Smart Grid applications

Wi-Fi supports IP and hence can support all IP-based protocols Smart Energy Profile 2.0 support will be available on Wi-Fi

Wi-Fis large set of interoperable profiles (e.g. supporting different powerconsumption requirements and data rates) allows for optimal support of a wide

range of applications

Wi-Fis presence in other devices such as handhelds and consumer electronics(independent of specific Smart Grid requirements) opens up possibilities for

application development that other technologies cannot support

Huge and growing -- installed based provides attractive market incentives fordeveloper investment in Wi-Fi-based applications
