we are currently working on our thesis project and this is about measuring signal strength in different wireless signal. were using inssider 2.1 version in our project and our problem is we configure gps in our comp. latitude and longitude were obtained but we dont know how to convert these parameters in distance.

One more thing is we dont know where is the transmitter gps reading and the receiver gps reading.
where confused if the gps reading below might be the receiver reading or the above gps reading with the APs were the transmitter gps reading or there just the same??!!..

please help us our final defense is fast approaching...

and also there is reading in the gps device itself. were really confused.
