Are you frustrated by coverage maps from the cell companies that basically are either outdated or not accurate?
There are some new tools that you can use to help report to others and share what the “real” coverage is in a particular area.
AT&T for one reports coverage in areas that have little to now coverage. One such place is my home, where I am lucky to have coverage. The AT&T coverage map online shows excellent coverage, you call their support number and they tell a different story, and they say they will get it fixed, and it has been years and still not fixed. Why does AT&T choose to deceive potential customers? Their ads for the best coverage at 97% of the country, that also carries disclaimers…

Excuse our server guys, we’re struggling a bit with all the traffic so we’ve disabled zooming on the heat map temporarily. Check out our twitter @opensignalmaps to stay up to date, and if you’re an Android user, download our app from the Android Market and help us crowdsource our map.

We’re planning on rolling out an iPhone App and a plethora of other features soon…so check this space often.

OpenSignalMaps is creating accurate cellular signal maps based on real-world usage data. Users can download the free OpenSignalMaps Android app, which acts like a “dashboard” for cellular signals by providing information on signal strength, data.

The OpenSignalMaps team consists of four former Physics graduates: Brendan Gill, Sam Westwood, Sina Khanifar, and James Robinson. They were inspired to start OpenSignalMaps after working with customers of their first startup, RepeaterStore, which sells mobile base station repeaters for domestic use in the US. They got to thinking: what would happen if you could map the world’s wireless signals with the users themselves?
