In our April 16 article "3G and 4G Wireless Speed Showdown,"
we reported the results of our exclusive 13-city tests of the four
national wireless services: AT&T, Sprint, T-Mobile, and Verizon. Our
study is the largest and best-known independent test of wireless
service in the United States.
Here, in Part Two of our story, we drill deeper into the massive
amounts of data that we collected over six weeks in February and March
of this year. Whereas the first article reported the 13-city average
speeds of the carriers, in this story we detail the carriers'
performance in each of the ten testing locations we visited in each
city.
We've assembled a
full-page map showing all 127 of our testing locations
in Atlanta, Boston, Chicago, Dallas, Denver, Las Vegas, Los Angeles,
New Orleans, New York, San Francisco, San Jose, Seattle, and Washington,
D.C. When you zoom in on a particular city, you'll see ten blue map
markers--one for each place we tested. Click the pin, and you'll see our
full testing results for that location.
T-Mobile's HSPA+ 21 service dominated the 3G testing, earning the
highest marks for upload speed and download speed in 11 of the 13 cities
we studied. The exceptions were Chicago (where AT&T captured the
best download and upload speeds for 3G) and Dallas (where AT&T took
the lead for 3G downloads, and Verizon won for 3G uploads).

We saw three major 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.),
AT&T won for downloads and Verizon prevailed for uploads. Notably,
in two of the cities where Verizon ruled (Denver and Seattle), AT&T
doesn't offer 4G LTE service.
Web Page and Video Load Times
In addition to the speed results, you can see the results of our
"behavioral" tests, which are meant to closely approximate the wireless
usage of real people. At each of our testing locations, our field
researcher loaded a 100KB static Web page and viewed a 1-minute video
while connected to each of the 3G and 4G services of the carriers. For
each one, the researcher logged the time the Web page took to load, as
well as the time necessary to stream the video.
