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 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,

12Wi-Fi: The Intelligent Choice for the Smart Grid
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

13Wi-Fi: The Intelligent Choice for the Smart Grid
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

15Wi-Fi: The Intelligent Choice for the Smart Grid
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
