I am thinking about buying a 4400 controller and converting my APs to lightweight to solve a major problem I have, but am unsure if I am reading the capabilities right.
I have a dozen symbol handhelds roaming around my outdoor facility that use the WLAN to connect an interactive telnet session to a VMS host. Right now, as the units roam, they disconnect from one AP and connect to another with the same IP, but it leaves the previous telnet session in limbo and they have to log on again. I have to repeatedly log off the orphaned sessions (session timeout doesn't work for other reasons). Am I reading the capabilities of the 4400 correctly that it says it maintains session(s) as the client roams? I would assume that this is the fact if it is designed to support VOIP over WLAN, but would like confirmation from someone who has the system installed.
