Handover performance.

[roby]

Hi, 

 I have build a small ESS with 2 access point hostapd based and an access 
server with freeradius. The system works with WPA and EAP-TLS 
authentication. 

A this time I'm testing the handover delay, for VoIP applications. The 
problem is that pre-authentication doesn't seem to work correctly.
I made some test, and the delay time is between 4 and 5 seconds. As you can 
understand it's a very long delay....
I set di Hostapd.conf for support IAPP and also RSN/WPA2 pre-authentication
but... 

Can somebody help me to set the pre-authentication? Did anybody make some 
similar test? All suggestions are wellcome! 

Thanks for your help,
Sincerly
