Speedtest data shows that T-Mobile has the fastest 4G LTE pipeline in the nation66
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 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.
