There's not much published on the adaptability of Wi-Lan to a mobile environment.  
What is published is mainly for car usage.  Apparently speeds above 40mph start to 
affect link quality due to doppler shift.

What I have read suggests that 802.11b would probably be more reliable in an R/C 
ground (bouncy) application because of the less complex encoding methods.  
Especially if it was throttled down to 1mb per second.

Basically someone is going to have to experiment with 802.11b and g to see if it 
would work on the battlefield.

I had a 2.4gh (probably 802.11b) camera system on my tank during the last battle.  
It worked great when the tank was standing still.  It also worked OK when the turret 
was rotating.  When the tank started bouncy around was another matter.  The picture 
would cut out and then re-acquire.  After about 10 seconds or so of bouncing the 
picture would never re-acquire.  I had to power reset the camera system to get a 
signal again.

I have a new 900mhz camera system I'm experimenting with.  So far it seems much more 
resistant to shock and vibration.

If someone wants to bring a Wi-Lan equipped vehicle to a future event I could 
provide a 100mw 802.11b access point and 180 degree antenna to cover the battle 
field.
