Hi Don,
when you drive normally you cannot able to navigate to internet, is  
very dangerous. But when you are in parking that's sound good. So a  
second operator in car with me have good delay of ping around 63ms to  
car speed of 80Km/h near the AP...about 15Km in LOS.

For VoIP we use Teamspeak, with 3/4 users in the server connected the  
streaming is good.
