so your clients will roam without packet loss when moving from one zone to another?
Of course, why wouldn't they? Done right roaming is under 50 ms without the need for a re-auth. We do voice and video over wireless without problem. But you have to control the spectrum really well.
Sure it's inherently flaky but it designed and installed well it works well. Provided noise sources don't crop up after you've eliminated them. But the system tells you and locates noise for you anyway.
