Although basic WiFI isn't designed for easy roaming it works if the new AP you hit has the same SSID, different channel, and same DHCP server. I have 3 APs over a few acres and handoff works very well even while on a SIP call. I wasn't expecting to stay on a SIP call but it worked. Other apps like internet radio with the large buffer don't even give a click or any indication of the handoff.

A large campus might and likely segments the network and doesn't account for WiFI handoff. However the N8x has one of the better WiFI setups I've used. Mileage may vary though.
