<March 2008> doc. : IEEE 802. 15<15 -08 -0199 -00 -wng 0> Smart Grid Territory and Nodes • Very wide service territory: • Ill defined • Possibly non-contiguous • Possible overlap. • Nodes characterized: • moderate to high value • non-mobile • typically non-optimal locations. • Nodes have substantial power • Plenty of processor • Do their job locally • Power constraint minimal • Power restraint appreciated. Submission Slide 6 <George Flammer>, <Silver

<March 2008> doc. : IEEE 802. 15<15 -08 -0199 -00 -wng 0> Smart Grid – Process Control Smart Grid applications are best defined as wide area process control • Low BW, (10 x 4 k. B per day) • Latency tolerant (~10 second) • Exceptional events require low single digit responses (e. g. 2 seconds) • Complete ubiquity: every customer location connected • Load control (“demand side management”) is inside the home and business Submission Slide 7 <George Flammer>, <Silver

<March 2008> doc. : IEEE 802. 15<15 -08 -0199 -00 -wng 0> Smart Grid – Conservative Design • Smart Grid performs command control for nations power infrastructure; it must be secure from inception. • Service life and Total Cost of Ownership is major consideration • Once emplaced, nodes should work reliably, upgradeable until removed. • Standard technologies-well vetted are most cost effective, they have known performance, largest ecosystem.
