3G and 4G Wireless Service in 13 U.S. Cities
When you look at the data in our 2012 study of 3G and 4G wireless service city by city, certain larger patterns emerge. Most notably, T-Mobile's HSPA+ 21 dominated the 3G testing, earning the highest marks for upload speed and download speed in 11 of the 13 cities studied. The exceptions were Chicago (where AT&T captured the best upload and download speeds for 3G) and Dallas (where Verizon won for 3G uploads and AT&T for 3G downloads).
We saw three main patterns in our 4G test results. In five cities (Atlanta, Boston, Las Vegas, Los Angeles, and San Francisco), AT&T swept the 4G upload and download competitions; in four (Denver, New Orleans, San Jose, and Seattle), Verizon swept both; and in the remaining four (Chicago, Dallas, New York, and Washington, D.C.), Verizon won for uploads and AT&T for downloads. Notably, in two of the cities where Verizon ruled (Denver and Seattle), AT&T doesn't offer 4G LTE service.
For details on how we conducted the testing for our 13-city study, see "Methodology in a Nutshell." Now let's take a look at the individual charts for each city.
