RootMetrics assesses carrier performance in airports

Each of the carriers have their respective strengths in this regard. Verizon is widely regarded as the reigning champion and AT&T is not far behind. However, T-Mobile is capitalizing on acquisitions and the abandoned AT&T merger goodies, and that has made Team Magenta a serious player in coverage and performance.
Verizon’s top performance was handed in at Baltimore-Washington International, but its absolute fastest recorded data speed, 101.2Mbps, was at Chicago Midway. AT&T placed second to Big Red in terms of median speeds, but did not score as many overall “wins.” Overall, Memphis International was AT&T’s best performer, edging T-Mobile who also got its highest score in Memphis.
When you couple these measurements with RootMetrics’ report for the second half of 2014 “drive test,” it is, for now, a three horse race in the US wireless market. You can view more details about the report by clicking the source link.
