More evidence that AT&T’s data network is head-and-shoulders above Verizon’s comes from Root Wireless, a start-up in Bellevue, Wash., that is developing software for consumers to install on their smartphones to do continuous network tests. This generates empirical data for consumers who “today are buried under opinions and advertising slogans,” said Paul Griff, the chief executive. Root Wireless has no business relationship with any carrier.
This year, Root Wireless ran 4.7 million tests on smartphones for each of the four major carriers, spread across seven metropolitan areas: Chicago, Dallas, Los Angeles/Orange County, New York, Seattle/Tacoma, the San Francisco Bay Area, and Washington. In every market, AT&T had faster average download speeds and had signal strength of 75 percent or better more frequently than did Verizon. (A Verizon spokesman declined to comment about these test results or those of Global Wireless Solutions.)
Never ask two questions in a business letter. The reply will discuss the one you are least interested, and say nothing about the other.
