7925G roaming on moving cars

[Tony_S]

Has anyone have any experience with 7925G and roaming while traveling in golf cars and going 20K speed ?

We have no disconnects from cucm when walking between access points, roaming works well and no reregistrations occur.

We were hoping to get the phone to ring while driving, and then take the call at a standstill, but phone unregisters and we get no ring.

Thanks for any input.

The wireless handset 7921/7925/7926 have very good roaming capabilties because the firmware is very, very mature.  

There are several factors which can affect roaming of the handset.  They are: 

1. Configuration of each phone; 
2. Firmware loaded on each phone; 
3. Wireless overlap; 
4. Co-Channel Interference;
5. Wireless configuration

I always recommend operators to load firmware version 1.4(4) in the phone (the later the better).
