On: Using wireless network signals to see through walls

I don't see why the base station needs to be inside the building. Radio waves go everywhere.

That is, as long as the building isn't a Faraday cage.

Seems to me though that the radiowaves would have to go in the general direction of the person moving, right? I suppose you could surround the entire building and go from there...
