- Windows 7 Map exposes the data that Microsoft has been collecting from virtually all Windows mobile phones, using them essentially as global wardriving machines. You can use this tool to accurately locate virtually any router in the world, as well as position Windows phones.
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 Microsoft.
This page allows you to ping that database and find exactly where any wi-fi router in the world is located. Note that iPhones also send this BSSID and Cell Tower Information up to Apple, as well.
You can enter any router BSSID/MAC address to locate the exact physical location below, or try the demonstration router by hitting "Probe" below.
