* Frankly, you could’ve knocked me over with a feather when I read the Crain’s story about how AT&T had been rated the best mobile phone carrier in Chicago…
For the first time, AT&T finished first in calls, web surfing and text messaging on wireless phones, according to Root Metrics, which routinely tests networks in cities nationwide. AT&T dethroned Verizon Wireless, which previously had the best overall score.
AT&T’s edge is network speed more than quality. AT&T and Verizon were virtually tied in reliability.
Root Metrics, based in Bellevue, Wash., said AT&T’s download speed is 19.1 megabits per second, compared with 13.5 megabits for runner-up Verizon. […]
AT&T tied for the lowest rate of dropped calls, at 0.2 percent. […]
For AT&T, the study helps validate the billions the Dallas-based company spent in Illinois in recent years. It spent $2.6 billion on wired and wireless networks in Illinois between 2010 and 2012, followed by another $625 million in the first half of 2013. Although AT&T didn’t break out wireless spending, it has been adding infill networks aggressively in high-demand areas, such as Navy Pier, to take loads off the overall network.
