T-Mobile is starting to clock some impressive download speeds on its newly upgraded LTE networks in different parts of the country: 30.2 Mbps in Columbus, Ohio; 24.1 Mbps in Boston; and 19.3 Mbps in Kansas City. And these are just averages. T-Mobile has recorded peaks speeds as high 86 Mbps on what it’s calling its Wideband LTE network.

Wideband LTE is now in 21 cities and metro regions, giving subscribers access to anywhere from 50 percent more to double the bandwidth of T-Mobile’s regular 4G networks. That equates to theoretical peak speeds of 100 Mbps to 150 Mbps, though real world speeds are far lower due to imperfect conditions of mobile networks.

[company]T-Mobile[/company] basically has been piling more spectrum onto its network, a process that started way back in 2012, when the failed AT&T-Mo merger landed T-Mobile with a bunch of consolation airwaves. T-Mobile opted to launch an LTE network, and CTO Neville Ray began a complicated refarming process of T-Mobile’s existing frequencies, shutting down 2G capacity and shifting 3G to other bands. In 2013, T-Mobile acquired MetroPCS and a windfall of 4G spectrum in key big city markets, which Ray in turn added to his game of spectral musical chairs.

The end result is that T-Mobile is now able to field big blocks of spectrum in big cities for 4G services, in some cases as much as 40 MHz in Dallas and Detroit, though in most areas it’s using 30 MHz. Meanwhile T-Mobile is starting to launch new LTE networks in a much lower frequency band, which will extend its now urban-focused 4G service outside of cities.

That’s why we’re seeing boasts from T-Mobile of having the fastest network in the country. In many places it’s right, and not just in cities with the wideband upgrade. Even in markets where it may not have more spectrum than its competitors, T-Mobile is still half the size of [company]AT&T[/company] and [company]Verizon[/company], meaning it has fewer customers vying for the same capacity.

But the other carriers certainly aren’t standing still. This year Verizon rolled out a new 4G of its own, which it calls XLTE. It uses 30 MHz to 40 MHz blocks of spectrum just like T-Mobile’s, though you’ll need a newer Verizon phone or modem to access its higher speeds.

AT&T is preparing its own upgrade, using a new LTE-Advanced technique called carrier aggregation. It essentially bonds spectrum from different bands together, but the end result is the same: more capacity and higher speeds. [company]Sprint[/company] is in throes of upgrading its Spark network, bringing it to more markets and using carrier aggregation to boost its overall bandwidth.

T-Mobile eventually plans to bring that it will bring its Wideband LTE service to 22 of the top 25 cities, but it’s not quite there yet. While its in 21 metro regions already, some of them are hardly top 25 markets, Boise, ID; and Birmingham, AL; for instance. Here’s a complete list:

  • Atlanta, GA
  • Boston, MA
  • Greater Bay Area, CA
  • Birmingham, AL
  • Boise, ID
  • Columbus, OH
  • Connecticut
  • Dallas, TX
  • Detroit, MI
  • Honolulu, HI
  • Houston, TX
  • Jacksonville, FL
  • Las Vegas, NV
  • Los Angeles, CA
  • Minneapolis, MN
  • Mobile, AL
  • Orlando, FL
  • Greater Philadelphia Area, PA
  • Portland, OR
  • Seattle, WA
  • Tampa, FL
  • Upstate New York Area

  1. Faster download speeds are great but what about the fact that I can’t get service in areas that Verizon customers. Very frustrating when you NEED your GPS or in case of an emergency need to make a call. So, I vote for better reception than download speeds. And, I live in Pittsburgh, PA so it isn’t like I’m in the middle if the country. But, to get out of PA there’s a lot of country roads and sometimes no houses or service stations for many many miles. Very frustrating :(

  2. There are more cities that have Wideband LTE that are not listed – also, why are we getting impressed by 20-30Mbps, when HSPA+42 should be delivering these in real time anyway. So there is definitely a flawed system and technical issues that show both HSPA and LTE are not living up to the expectations they should, and while more spectrum is being thrown at the problem, the reality, the network, infrastructure, base stations, back haul, and antennas all need to be massively overhauled and fine tuned to get MORE speed and coverage from LESS spectrum – as was the plan with LTE all along. So I hope after throwing all the spectrum T-Mobile is at the issue, they go back and retune things to be more efficient, then those 20Mbps speeds we see in “Wideband” will go to 80-100Mbps as a combination of spectrum and perfect tuning…Like LTE was supposed to be.

    However, being a T-Mobile customer, I appreciate anything they are doing positively and am grateful for the speed I get.

  3. I’ve been seeing Speedtest results in the 60 Mbps range in parts of Columbus for a few months now, and rarely do I see anything under 20 Mbps. Say what you want for T-Mobile’s coverage outside of larger cities, but I couldn’t be happier with their performance and coverage in my area, especially given the very low rate I pay.

      Well, here’s what we know from your test.

      First, The test was next to the Northwest Outpatient Medical Center, Northwest Arthritis Center, and a respectable Eye Clinic at 8am.

      Next, Based on pingtimes, and upstream rates, the cellsite that is serving you is on Comcast’s network. To confirm this, I checked Comcast Business website, and confirmed that Comcast could bump the business-class speed to 150MB/s in that area for $50 additional per month if T-Mobile had a need to. So to get faster speeds, call T-Mobile and complain. Ask to file a engineering trouble ticket with T-Mobile and see if they’ll upgrade the speed.

      Still at 8am, I imagine very few people were using the service. I also have doubts that people would be using their devices if they’re waiting for one of these doctors. With arthritis, Their fingers probably hurt, or at the blind clinic, they can’t see the screen clearly to watch TV in the doctor’s waiting room.

    • I live in SF, and regularly see 9-15Mbps as the norm, but in some areas 20-30Mbps (downtown) is the norm, and in Civic Center, on the Van Ness side, it is usually 35-55Mbps – however, this is running off 10 and 15Mhz spectrum. Once they start deploying carrier aggregation in SF (which they own more spectrum than any other company) they should be hitting speeds that make peoples face melt.
