Excellent way to guage wifi strength for a location
The map functionality is awesome if you have time, but even if you dont have the time to make a map, you can simply spend 5 or 10 minutes going a certain known distance and taking a reading. In most of the sites I service, this was more than adequate to get an idea of the wifi strength and weaknesses.
This is NOT a basic site survey tool. It is best suited, in my opinion, to determining signal strength, and it does this VERY well! Highly recommended for this purpose!
