It will work wherever there are ambient WiFi signals, indoors or outdoors. This is particularly interesting indoors because it’s possible to get GPS outdoors, while you can’t indoors. We have tried mapping around Mountain View and it’s worked great

My specific use case is in tracking very small movements, i.e. ones that a GPS would not pick up. I was wondering if this would provide a solution to that, but it still seems to have a delay attached.

Doesn't take away from some very impressive tech on display. Kudos.

thanks! How small are the movements you’re trying to track? And what kind of time delays are you trying to get under? You can try mapping the same location multiple times (the more mapping the more accurate our system will be)
