a proper handoff on both sides means i don't even realize it happening, let alone re-associate with DHCP and all that jazz - it happens at the MAC layer and isn't visible to the OS unless it asks the current station BSSID and decides to do something about it. "APs properly configured" comes into play here heavily.
In principle, yes, but I've never seen an OS network management infrastructure which eliminates this bureaucracy when switching APs or does this seamlessly. For example, as far as I know, neither my Ubuntu laptop nor my Android phone will automatically switch APs with the same ESSID. They'll hang onto the old AP for as long as possible, then drop it and reassociate, with DHCP jazz and all. However, I would think that putting the client on a static IP would largely obviate this. Have I just missed a subtle shift in implementation over the last few years? I don't have two APs handy. Or are WiFi SIP phones specifically designed to work as you describe? -- Alex Balashov | Principal | Evariste Systems LLC 303 Perimeter Center North, Suite 300 Atlanta, GA 30346 United States Tel: +1-800-250-5920 (toll-free) / +1-678-954-0671 (direct) Web: http://www.evaristesys.com/, http://www.csrpswitch.com/
