Global Wireless Solutions is one of the companies listed in the story. After placing more than 3 million calls this year, concluding more than 2 million wireless data sessions and covering 3 million miles of asphalt, the company concludes that AT&T's data throughput is 40 to 50 percent higher than the competition which includes Big Red. Conducting 4.7 million tests on smartphones for the top 4 U.S. carriers (Verizon, AT&T, Sprint and T-Mobile). a company called Root Wireless went to 7 major metropolitan areas and concluded that AT&T had faster download speeds than Verizon did and also had 75% or more of it's signal strength more often than Big Red had. These findings seem to go against the results recently published in Consumer Reports where Verizon was named the best carrier and AT&T was at the bottom in fourth place. The reason for the difference could be that Root Wireless' software will not run in the background on the iPhone which means other smartphones had to be tested besides Apple's touchscreen handset. You don't have to be a member of Mensa to understand that if AT&T's coverage improves that much when the iPhone is excluded, perhaps the problem is with the device-not the network.
