Google Map of US Cell Phone Coverage

CNET Cell Phone Coverage Map

CNET have created a Google Maps mashup to compare cell phone coverage in the USA. The map shows the coverage of AT&T, Sprint, T-Mobile and Verizon in 16 US markets.

Currently the map shows data for the following locations: New York, Los Angeles, San Francisco Bay Area, Seattle, Chicago, Washington D.C., Dallas, Orange County, Las Vegas, Boston, Philadelphia, Atlanta, Minneapolis, Denver, St. Louis and Houston.

CNET teamed with Root Wireless to create the coverage map. The data was collected from client applications placed in consumer phones to record performance data such as data throughput, dropped calls, and signal strength.

The map uses coloured hexagons to show the signal strength in different areas. This allows the user to get a quick overview of where signal strength is good or patchy. It is also possible to click on any of the hexagons to get a more detailed breakdown of the signal strength at any location.
