Mapping MAC addresses

“android map exposes the data that Google has been collecting from virtually all Android devices and street view cars, using them essentially as global wardriving machines.

When the phone detects any wireless network, encrypted or otherwise, it sends the BSSID (MAC address) of the router along with signal strength, and most importantly, GPS coordinates up to the mothership. This page allows you to ping that database and find exactly where any wi-fi router in the world is located.” (source)
