How to setup Zero Handoff on Ubiquiti Unifi.

UniFi has always supported roaming according to base 802.11 standards. However with Zero-Handoff Roaming enabled, clients can freely roam between UAPs without incurring any latency penalty as a result of the roam. The basic premise is Zero-Handoff enabled UAPs appear as a single AP from the perspective of the client, thus eliminating disconnection.

Zero-Handoff Roaming is available starting with v3.x.
