I hope I don't sound to ignorant here, too often thats the
case.
But If you have a known working Wifi AP with a high end
reputation like Cisco Airnet model 2400 for instance.
They advertize 1 watt, it's one watt no funny bones about it
or busnesses wouldn't respect their higher prices and pop for
it.
Take an EMF meter like the one on Ghost Hunters TV show,
radio shack has them, and set it ten feet LOS from the AP
[Cisco] wile downloading a big video file or something large,
and set that as your "One Watt" point, now you have a
comparason, of course notice the Antenna "Type" and location.
Heck you can use a cheap NetBook with built in WiFi and
NetStumbler software to measure the IF strenth. All you have
to be sure of is the output of your "Sample" source.
My Alfa USB WiFi unit LIES!!! they claim a half a watt, NO
WAY!!! I bet if Cisco built it they wouldn't lie about that
stuff, and of course it would cost more than 60 bucks.

They do make a nifty $100-200 or so WiFi spectrum analyzer
which has a calibrated receiver. And, if you have a wifi
card with an exernal antenna, you can do even better.
