extending range of 802.11
(OP)
anyone have experience extending the range of an 802.11 wireless link? if I wanted one in a car and wanted to talk to a stationary computer, how far could I go?
directional antennas, or lower noise amps, and PAs will help, but PAs are FCC violation i'm sure. but more sensitivity is the answer, i'm sure.
wwyd?

I think a better (higher) antenna system is your best option. But keep in mind that the transmission line losses will be very high at this frequency, so you will need to have the transmitter (generally in your wireless router) very close to your antenna.
At 2.4 gHz, propagation is strictly line-of-sight. So if you are trying to connect to a base station from a car, getting the antenna as high as possible, and outside, should help.

"more sensitivity" is the answer only to a certain point. Once you can hear every 2.4 GHz microwave oven and every 2.4 GHz cordless phone in the city, then further sensitivity doesn't help. You'll be lucky to get a city block with Wi-Fi to a car.
Wi-Max (and Mobile Wi-Max) is coming in a few years.

Need line of sight obviously.
