Hotel phones stay associated to a distant access point at a weak signal while a nearer access point is idle. The WLAN already has fast transition. Which feature lets the infrastructure suggest that the phone move?
Select an answer to reveal the explanation.
Short Explanation
Fast transition makes the hop cheaper once the phone decides to go. It does not tap the phone on the shoulder, while 802.11v is that suggestion to move to the nearer access point. Your phone can still ignore it.
Full Explanation
802.11v BSS transition management lets the infrastructure suggest that a client roam to a better BSS. Sticky phones that remain on a weak distant access point are the case it is meant to influence, and fast transition only shortens a roam the phone has already started. Suggesting the nearer access point is the 802.11v behavior. Hiding the SSID does not rank access points and does not force a phone onto the nearest one. Phones often cling harder when they have to probe for a hidden name. A unique VLAN per access point turns every roam into a Layer 3 event. It does not make the nearer access point mandatory, and it adds a disruption the hotel does not want. Open authentication removes link security. Sticky behavior is a client roaming decision, not a consequence of encryption, so removing encryption does not make phones pick the nearer access point. Exam caveat: BSS transition is a request. A phone may refuse and stay put, so 802.11v is not a guarantee that every sticky client will leave. Operational check: on a sticky test phone, confirm a BSS transition request names the nearer access point and watch whether that phone model actually roams.
