Has anyone considered that, when a phone is in the hand of its user, it's unlikely to be uniformly omnidirectional and, instead, may have a pattern with lobes? If this were the case, one direction will probably be most sensitive. Once that pattern is established, then I would suspect it wouldn't be too difficult to plot signal strength against it. Of course, influences of the building's structure (pillars, walls, cube frames, coke machines) would impact the placement of perceived radio sources.

I tested wififofum radar in a building with 40 AP's.. It was totally
off. It's a guess at best.

The scanning feature is nice though.

My theory was along the lines of your second but I was stuck on how if
you turned it on in a location it knew where to place them for the
first position. We didn't test that so it may just randomly distribute
them round the map and work it out once you start moving. As it has a
compass built in it knows which way you are walking and if it is
getting weaker the signal will probably be behind you.
