Really? Can this take place seamlessly mid-call? With DHCP? What about DHCP lease acquisition delay?
An access point is an L1 bridge; everyone on the wireless side of every AP are all on the same LAN with the same addressing.
Would such a configuration involve merely bridging all the APs on the same LAN segment so that the same DHCP server feeds them? If so, where's the guarantee that the DHCP server will lease out the same IP address to the client?
Access points. Not routers.
This implies that a level of intelligence/sophistication is (or isn't) in the client unit that when it bounces to a new AP it wouldn't run a refresh on the lease. It would be very reasonable to think that an AP with the same name might be on a different subnet (different regions/depts of a large building, or whatever), which would then render the call dead. What you're suggesting is intelligent handoffs similar to a cellular network. -Aaron
