What kind of encryption and authentication are you using? In my  
experience associating between access points works fine using open  
(time taken to reassociate to another isn't really noticeable) but  
will not work reliably with WPA2 EAP TTLS due to the amount of time it  
takes to reauthenticate. Using WDS will help in that case. I tried  
this out with Nokia E61(i) and E90 terminals and AP1130s late in the  
summer.

As to your question; using open, calls are probably not going to be  
dropped but you might lose some frames when reassociating :) Using  
WPA2 EAP and all the nice things for OTA encryption needs some thought  
before implementing.
