Too bad the noise floor in most parts the bay area is at around -95 -> -85 these days...

Possibly. There are many ways to increase receive sensitivity. If you are dealing with thermal noise, you want nice low noise amplifiers such as GAS-FETs. Folks with earthstations would even run liquid nitrogen to lower the tempature of the LNA electronics to get the thermal noise down, although I don't think I want a tank of nitrogen tied to my laptop. > And what's the effect on range of having a high receive sensitivity on > the client side but not on the AP side? I guess packets get there but not come back. :-) You ussually want both.
