Fast Transition - does it work with WPA2-Personal?

Does the Fast Transition feature work when using WPA2-Personal encryption? I read somewhere (not on Peplink site) that Fast Transition (aka Fast Roaming) only works with WPA2-Enterprise and RADIUS. Please advise.

I can say anecdotally that when I turned it on, all of a sudden devices shifted between my 3 APs and attached properly to the closest AP and I’m running WPA2-Personal AES. I was so happy this feature worked because I was struggling with devices connecting to the farthest AP all the time… IE the devices initial AP selection criteria/programming sucked and when I turned on fast roaming, all of a sudden the devices started to move appropriately to the closest AP, so something about fast roam gave the clients the ability to evaluate multiple APs and make a better decision.

Appears the Fast Transition feature is not available for SSID that are open (not secure). That is the case with most guest networks. Is there a technical reason the feature would not work without encryption?

@Don_Ferrario

Fast transition is the standard defined for the 801.11r to reduce the association process when roam from 1 AP to another 1 AP.

For more information how “Fast Transition” association process work please refer to the URL below:

Generally “Open” association SSIDs doesn’t go through the above process and by design it’s not secure if you freely roaming to second AP, hence most of the Operating System (OS) is blocking you to connect to second AP even the same SSID (open) is used. Just give a example if hacker can easily setting up a SSIDs and treat your device to roam to the SSIDs that will be very dangerous that all your data will be leak out when connect to the AP. Hence. it’s a standard for “Open” SSID such feature will not even being considerate.

That is the exact article I was originally referring to. And it implies that Fast Roaming only works with WPA-Enterprise & RADIUS. But, I believe, in Peplink’s case, Fast Transition works with both WPA-Personal and WPA-Entertprise. I am just trying to confirm that this is indeed the case.

@peppypeplink

The 802.11r standard actually refer to WPA2/3 (Personal) and WAP2 Enterprise.

Ah, how did I miss that reference?! Thank you for pointing it out. I am glad to have confirmed that Peplink’s Fast Transition does apply to WPA-Personal. I have just implemented it using a Balance One with AP One Ruggeds and it has greatly improved iOS device handoffs.
