That's useful. It should be possible to do almost as well with a suitably programmed phone, if you can get to the RF control level. What's needed is something that gives to the app level the same kind of info that's available for nearby WiFi stations. Then anyone could write analysis apps.

"Cell tower pinning", so that your phone remembers the cell towers in an area and reports new ones, would be useful. When a new one pops up, that's an interesting event. That capability would be useful for other purposes, such as finding and reporting coverage holes.

It's actually not that easy to get those events or debug info. There is one class of intel chipset that you can get it from, though:
