So awseome and crazy that its free.

We had a few rouge devices in our building. I easily added a PDF of a floor plan and within minutes I had a general area of all our access points. I took 30 total data points and it narrowed down the broadcasting device that we were looking for down to the exact cubicle.

I plan on scanning in the floor plans for our house and plot it out now to see exactly where my wifi reaches and how to extend it to reach the dead spots in the house.
