6. May 2010 Listing of pertinent use cases
In order to create a list of functional requirements for the Smart Grid, an exercise was performed to list all pertinent use cases that involve network communication. Sources for this information include the Southern California Edison Use Cases, Grid Wise Architectural Console use cases, EPRI and others. Use cases from all of these sources were selected based upon a network requirements basis. From this research the following high level use cases have been identified

11. Topic #2 Summary Suitability of 802.11 to Smart Grid
May 2010
Topic #2 Summary
Suitability of to Smart Grid
As is – Generally complete
With addition of TGs mesh and S1G – enhanced range and application diversity
Anything Further??
Nothing proposed
