Help create a Global Map of Cellphone Signal Strength

Mobile Phone Cell Coverage London
Fed up with network coverage maps from cellphone providers? is on a mission to create an accurate, real-world global database of signal strength.

To do this, they gather anonymous data through a free Android App, which is then uploaded to the opensignalmaps website – apparently the Iphone doesn’t allow application access to signal strength readings.

The map currently shows cell tower locations and cell coverage, but they plan to add other data including Wi-Fi access points.
