Along with Sprint and Verizon, T-Mobile and AT&T have also made improvements in the Fourth Round by adding the number of locations served by at least 6 Mbps down and 1.5 Mbps up. While T-Mobile experienced a hiccup downward in the Third Round for the locations their phone serves, AT&T has made steady progress. While T-Mobile has slightly more locations served than AT&T, AT&T has higher average speeds. This is likely due to the fact T-Mobile's coverage is more limited and concentrated while AT&T's is more spread out and diffuse. AT&T's higher average speed may also be explained by the fact that the maximum speed registered by AT&T LTE, 44.000 Mbps, is much higher than that reached by T-Mobile LTE at 33,000 Mbps. AT&T also has many locations where they just missed making the served threshold.
