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?
