Roaming with standalone APs

QuestionRoaming with standalone APs
Roaming is fundamental to the 802.11 protocol. As long as the SSID and security options are the same clients should have no problem Roaming. It is the client device driver that collects Access Point information and determines which Access point to associate/re-associate to. The Access Point just advertises its existence with Beacons, responds to probe’s from clients looking for better Access Points, and accepts or rejects association requests based on the security settings and available association slots (up to 255 per AP, restricted to 100 by Ruckus).
The Zone Director does include a Fast Roaming protocol unavailable with standalone AP’s. This is only useful for 802.1x WPA authentication where the PSK provided by the RADIUS server is cached by the Zone Director and provided to each new AP when the client roams without having to consult the RADIUS server again. Without the ZD WPA 802.1x roaming will still work but the AP to RADIUS server consultation may cause delays.
So there should be no appreciable difference with roaming except in the case of WPA 802.1x authentication.
The Zone Director does make sure that the SSID and security settings are uniform across controlled AP’s.
