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.

Re: T-Mobile
Yeah, any device with Qualcomm MSM8974 includes Cat 4 baseband processor. Also supports two 10Mhz component carrier in CA. More will come in 2014. 

Cat 6 will add support for two 20Mhz component carriers for 300Mbps peak throughput. Both Cat 4 and Cat 6 from Qcom will only support 2x2 MIMO though.

Re: T-Mobile
All of the current Cat 4 UE support 150Mbps peak rates in a 20Mhz downlink channel. 

Nexus 5, Note 3, LG G2 come to mind.

Re: T-Mobile
Dan, any word on the availability of commercial Cat 4 UEs that will be able to support 150MBPS on the downlink?  Since Qualcomm recently announce Cat 6 supported chipsets, this shouldn't be far away.

 

Note: 20x20 LTE is a great capacity play, but to take advantage of the potential throughput speed increases you'll need Cat 4 UEs.

Re: T-Mobile LTE
Well T-Mo can get up to ~225million covered with LTE if they completely overlay their existing HSPA+ footprint. After that number they'd have to get into their rural EDGE footpriint and modernize which makes very little economical sense with their high band spectrum.

Their short term options are buying a significant amount of 700Mhz A block licenses which would allow them to get a greater reach for less $$ invested, or long term wait till 2015 to get 600Mhz, and expand coverage in 2016. 

Everything else wouldnt make too much sense.

It will come down to access to spectrum to expand.

Maybe T-Mobile will be able to start covering more geographic area. Sprint has not really tried and does not seem to be interested in geographic expansion. We need a third geographically large wireless carrier to create competition for those stuck with only AT&T or Verizon.

Re: Trying out T-Mobile
There's a standard trial period for new customers (on T-Mobile or call carriers)? I didn't know this... Is that just on the postpaid side?

Re: Trying out T-Mobile
I know a lot of people will just use the standard trial period to test out another carrier's coverage. If it does not work they owe nothing or very little for testing another carrier.
