Why not use bluetooth low-energy for this stuff? Or would you need to have three beacons to triangulate?

1) range 2) clock precision (you can't measure time fast enough to actually measure position using bluetooth)

Interesting, why is that and how fast would that be, then?

Also what's different about triangulating via WiFi APs signals, that bluetooth doesn't work?
