DETROIT — AT&T is touting a new test that shows it has the fastest 4G LTE network in metro Detroit.

The study was conducted by the independent mobile analytics firm RootMetrics.

RootMetrics reported an average download speed of 18.6 megabits per second and an average upload speed of 9.0 mbps.

In their LTE Performance Review released today, RootMetrics called AT&T’s network “blazing-fast.” According to the RootMetrics study, “AT&T easily offered the fastest pure LTE download speed of any carrier.”   The RootMetrics LTE March 11, 2013, Performance Review is based on more than 725,000 4G and 4G LTE data samples gathered from the top 77 U.S. markets during the second half of 2012. AT&T had officially deployed 4G LTE technology in 47 of those markets at the time they were tested.

Additionally, in a test for Detroit conducted in January of 2013, RootMetrics named AT&T the top performer — taking the RootMetrics RootScore Combined Award — for its combination of call quality, text performance and mobile Internet speed.

And the reality is even better than the RootMetrics study showed. According to AT&T spokesman Jermaine Spight, the report says AT&T is only live with LTE in 47 of the 77 markets Root tested — but AT&T since the test has launched in 26 of the remaining markets. That leaves only four markets where Verizon has LTE does not.

Also, Spight said, AT&T is far faster in areas where non-LTE 4G networks prevail.
