They focused on data, not calls, and used their own testing script and methodology, which combined various kinds of uploads and downloads. Using laptops, more than a dozen people ran more than 10,000 tests; they found AT&T is both the fastest national 3G network, and the least consistent. Sprint's 3G system was the slowest of the 'big four' carriers, but the most consistent. When the test results were broken down by regions, AT&T led on speed in the Southeast, Central, and West, but T-Mobile took the crown in the Northeast region. Sprint's 4G network was fast where it was available, but it was surprisingly slower than 3G in some cities. The fastest AT&T download seen, at 5.05 megabits/sec, was right behind Apple's headquarters at 1 Infinite Loop in Cupertino, CA. The fastest connection in any of the tests was a blazing 9.11 megabits down on Sprint 4G in the Midtown neighborhood of Atlanta, GA. The slowest city, on average, was Raleigh, with average 3G downloads of 880kbits/sec."
