T-Mobile Quietly Kicks Off Double-Wide 4G

T-Mobile has quietly started deploying its 2x20MHz LTE channels in parts of North Dallas, a move to speed up its 4G network that will play out over the next couple of years.

AllThingsD reports that the service -- also known as 20-by-20 -- went on in parts of North Dallas over Thanksgiving. A Light Reading reader also said in late October that a T-Mobile US Inc. 2x20MHz test in Dallas showed maximum downloads of 148 Mbit/s.

T-Mobile CTO Neville Ray told Light Reading in October that the operator would work hard to get "very small" test markets up by the end of the year. "20-plus-20 is going to be a 2014 to 2015 story for us," Ray said.

T-Mobile is layering in AWS spectrum from its MetroPCS purchase to upgrade markets to 2x10MHz, 2x15MHz, and 2x20Mhz over the next two years. The operator expects to have fatter 2x10MHz pipes in 100 hundred markets by the end of 2014, including in 90% of the top 25 metro areas.
