Independent research firm RootMetrics finds AT&T’s network delivers fastest 4G LTE
speed of any major wireless carrier
COLUMBUS, Ohio (Mar. 12, 2013) — AT&T* wireless customers in the carrier’s 4G LTE markets**
have access to the fastest mobile Internet speeds on their smartphones.
How fast? RootMetrics®, an independent mobile analytics firm, has reported an average download
speed of 18.6 Mbps and an average upload speed of 9.0 Mbps, based on recent testing. That means
ultra-fast song downloads, faster photo sharing and app downloads, faster mobile Internet access—
virtually everything you do with a smartphone, just easier and faster.
In their LTE Performance Review released this week, 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.
―There are more reasons than ever to choose AT&T,‖ said John Donovan, senior vice president-AT&T
Technology and Network Operations. ―Nationwide, we are continuing to expand 4G LTE and expect our
deployment will cover 300 million people by year-end 2014.‖
Additionally, in tests for Akron and Columbus conducted in Jan. 2013, and tests for Cleveland
conducted in Oct. 2012, 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.
Over the past five years, AT&T invested nearly $98 billion into operations, more than any other public
