I'm not sure I want to be an "authority". Just think of me as a geek who occasionally gets it right.
I'm hoping for in-car mesh, btw. We would all have a < $100 802.11 transceiver in the car, with a little omni
where the cellular antenna would be for the non-geek crowd. Then you could hit some number of cars
from the side (so the doppler shift doesn't make the radios crap out) via somewhat more directional
antennas.
OK, someone shoot me, I'm starting to sound like Sam Churchill.

I'm curious about using 802.11 from my car. No less an authority than Jim Thompson explained to me at BAWUG last night that 802.11 was useless when the two communicating systems had a greater than 40-mph speed differential. This is apparently due to the doppler shift.As he pointed out, this wouldn't be a big problem with cars driving past access points, but would make it tough to put a directed antenna pointing down the road, since the cars would close in on it at fairly high speeds. I guess an omni way off the side of the road could provide service for a reasonable distance. Could anybody expand on this for me? I have to admit that I've had visions dancing in my head of in-car access for quite awhile, and I'd hate to think that it was unlikely to work...
