T-Mobile’s 5G network undergoes more speed tests before its official launch

After putting up near-500Mbps speeds in early tests last week, T-Mobile’s 5G network has once again been put to the speed test.

T-Mobile hasn’t officially launched its 5G network yet, but PCMag was able to sneak onto it with an unlocked Verizon Galaxy S10 5G in New York City and run several speed tests on it. The tests were run between 42nd and 46th Streets on 3rd Avenue in Manhattan ranging from 111 to 336 feet from a cell site.

So how did the network fare? Speeds consistently ranged from 350-490Mbps, says PCMag, and one test registered a speed of 493Mbps just like the other speed tests that were run last week. To compare, LTE was producing speeds between 62Mbps and 113Mbps. That LTE network had many more people on it than the 5G network that was probably empty, of course, but the 5G speeds are still solid.

T-Mobile is currently using millimeter wave (mmWave) spectrum for its 5G coverage, and it’s got 100MHz of 5G deployed. The cell radius in these tests is said to be around 400 feet.

T-Mo hasn’t said much about when its 5G network will officially launch. We do know that in addition to mmWave, T-Mobile will be using 600MHz spectrum for its 5G network rollout. 600MHz has lower peak speeds than mmWave but reaches farther distances, letting more people hop onto the 5G network. T-Mobile has said that it’s building its 5G network out in 30 cities across the U.S., including New York City, Los Angeles, Dallas, and Las Vegas.

The Samsung Galaxy S10 5G will launch at T-Mobile this summer. That device doesn’t support low-band, so it will be limited in the 5G coverage it’ll have access to. But if you’re the early adopter type who loves to be the first with new tech, you may be able to get an early taste of T-Mobile’s 5G if you buy the S10 5G and are in an area where T-Mobile has its mmWave 5G coverage turned on.

    That is bad compared to Verizon and Sprint.

    • Not Me

      Verizon sis using at least 400 MHz of spectrum that’s why.

        Perfect example why the Feds should not want any divestitures (as condition for merger approval).

        • SirStephenH

          The problem is that the feds seem to think that band 41 (2.5GHz) is equivalent to the lower bands, which it’s not. If you don’t include band 41, which has very different characteristics than the lower frequency bands, then New T-Mobile would have only slightly more spectrum than AT&T and Verizon.

    Not having the 5g phone not cover lower bands is insane. What a game!

    • ericdabbs

      That is why I am staying away from the 2019 Tmobile 5G phones until I can confirm the phone has the Qualcomm X55 modem which supports sub-6GHz FDD 5G which means 600 MHz 5G would be supported. Phones with the X55 modem should start to appear in Q4 2019 phones (perhaps Pixel 4, OnePlus 7t) but definitely should be standard in 2020 5G phones. There is just too much interest in the X55 modem chip to not start putting them into 5G phones for faster adoption.

        Your average phone user doesnt know that. They just think “i must buy a 5G phone now” so they can keep up with the joneses. Us bloggers are smarter than that!

  • Sharti24

    400 feet of coverage? Lol

    • Jason Caprio

      Considering T-Mobile’s mmWave is 28 – 39GHz, you can’t expect that to have any real range. At those frequencies, it is pretty much required to have line of sight to the cell site. Even the smallest obstruction would degrade the signal. mmWave reflects off most surfaces. Even the AIR is an issue for those extremely high frequencies. After about a half mile even at line of sight, it’s unusable. mmWave is strictly designed for small cells in densely populated areas.

      The 600MHz 5G will be the answer to range, however speeds will be much less.

      • Jay Holm

        So then how are we supposed to reach this GBPS future promised by 5G, if it only has a couple hundred feet range?

        • Jason Caprio

          That’s a good question. The only solution is to have millions of small cells everywhere! lol

        • John Doe

          And that will be the case, that will be the most reliable way to do it.

        • ericdabbs

          you need carrier aggregation between low, mid and mmwave bands. This is not the early stages of LTE where carrier aggregation was a new topic. Even when Tmobile gets its consistent fast LTE speeds, it is leveraging carrier aggregation between its B12, B2 and B4 spectrum.

    • SirStephenH

      Verizon has shown 1Gbps+ at up to 3,000 feet and wall penetration at close to 1Gbps at half that distance. I’m guessing it was tested at 400 feet, not that the actual coverage is 400 feet. Even Verizon’s early publicized testing was only done at 400-500 feet.

  • Chris

    So what’s the point of even buying a 5G phone right now? I really wanted the Note 10 but it makes no sense to get a phone that doesn’t even support all of the 5G bands T-mobile will be using.
