wifi question

Hello... when it comes to wireless..... is there a difference between seamless roaming and zero-hand-off roaming?
or is it the same thing, just two different ways of referring to it.

"The solutions and answers provided on Experts Exchange have been extremely helpful to me over the last few years. I wear a lot of hats - Developer, Database Administrator, Help Desk, etc., so I know a lot of things but not a lot about one thing. Experts Exchange gives me answers from people who do know a lot about one thing, in a easy to use platform." -Todd S.

Actually, they're not the same.

Seamless roaming means disassociating from one AP, then associating to another almost instantaneously, within the same ESSID.

Zero-handoff roaming means you don't actually disassociate from one AP to associate to another as the APs all look like the same single AP to the client.  This is typical of Meru's approach.  Similarly Ubiquiti have a zero-handoff mechanism also.

so in a way... zero handoff is a STEP Up from seamless roaming... is that a good way of looking at it?

Vendors would have you think that zero-handoff is better and in theory it is, but the implementation means you trade-off in other areas so it's not as perfect as it sounds.

I too prefer seamless handoff.
