Supporting LOC RR's

Once the AP knows where it is, the clients can find out where they are in physical (WGS84 coordinate) space using the APs as references.  Note that it's an enterprise solution - definitely not for most homes - since it requires at least 4, and probably many more suitable APs.

Actually, if the AP doesn't have GPS but does offer WiFi Certified Location Service, then it could use its own LOC record to provision itself...
