RootMetrics: Cell phone coverage survey

RootMetrics has completed their survey of cell phone coverage by network. They have created an interactive map that you can use to zoom/scroll around the country and see various coverage statistics (call performance, fastest speed, best technology) for all the major carriers at a fairly detailed resolution.

The results are not too surprising. Verizon has the best coverage, with AT&T not far behind. T-Mobile and Sprint cover most of the populated areas, but with what could be annoying gaps if you travel the countryside. For example, Oswego New York is has coverage by all four networks, but the surrounding towns (Wolcott, Fulton, etc.) have no T-Mobile or Sprint coverage, and some of the towns (like Sterling, where the Renaissance Festival is held) are only covered by Verizon.
