According to the results from the app, T-Mobile provides the fastest average data speeds over 4G LTE in the U.S. at 17.8 Mbps. The data also revealed that T-Mobile's speeds are more consistent than the competition. That's because the company has been able to offer 10 + 10MHz service in major markets like New York City, Miami, Chicago and San Francisco. In those markets, T-Mobile's 4G LTE service has been measured as high as 72Mbps for downloads, and 27Mbps for uploads. At that speed, a 90 minute HD movie can be downloaded in 5 and a half minutes, and an entire music album will take only 13 seconds to download over the carrier's network.
"T-Mobile is laser-focused on giving customers the best network experience possible. First we deployed nationwide LTE at breakneck speed, covering more than 200 million people in just six months. Now, we're adding more and more spectrum to this footprint and have commenced the launch of our Wideband LTE service, doubling already best-in-class speeds."-Neville Ray, CTO, T-Mobile
T-Mobile just turned on its first 20 + 20MHz LTE network in North Dallas as T-Mobile Wideband LTE launched. The service can provide download speeds as high as 150Mbps and a download speed of 147Mbps and an upload speed of 40Mbps have been measured in the area. T-Mobile says currently the Samsung Galaxy Note 3, LG G2 and the Nexus 5 will support the faster data speeds as the Wideband LTE is rolled out nationally. Three more Wideband enabled devices will soon be available from the carrier, namely the LG G Flex, the Samsung Galaxy Tab 3 (7.0) tablet, and the recently announced Sony Xperia Z1S which is a T-Mobile exclusive.
