T-Mobile Offers Fastest Wireless Data Performance in Top 100 Markets

December 20, 2010

Bellevue, Wash. — Dec. 20, 2010

T-Mobile now delivers the fastest wireless data performance in the top 100 U.S. markets according to results of a new, independent third-party study.1 In the study, T-Mobile’s overall network outperformed all other nationwide networks tested.

“2010 was a banner year for T-Mobile’s network expansion,” said Neville Ray, Chief Technology Officer for T-Mobile USA. “We have deployed fiber backhaul to our cell sites to deliver an industry leading mobile data experience on the latest T-Mobile smartphones and broadband devices. Today, we are delivering the fastest data performance in the top 100 U.S. markets on average, and it’s only going to get faster as we upgrade our network to offer 42Mbps capability in 2011.”

The study results are based on national drive testing conducted between June 2010 and November 2010 by a leading third-party research firm, which downloaded and uploaded files to test data transfer speeds on laptop data sticks for each of the major carriers.

T-Mobile also offers a broad range of 4G products, including handsets, laptop sticks and a 4G-enabled netbook, which enables its customers to reap the benefits of the 4G network. T-Mobile will continue to be at the forefront of wireless innovation, delivering 4G products across a variety of categories in 2011.

4G network coverage is not yet available everywhere. For more information about T-Mobile’s 4G services, see https://www.t-mobile.com/coverage.
