As promised, OpenSignal’s latest report on U.S. mobile networks is in, and T-Mobile nearly won every award.

OpenSignal today shared its State of Mobile Networks: USA report, which examined the networks of AT&T, Sprint, T-Mobile, and Verizon from October 1, 2017 through December 30, 2017. During this period, OpenSignal looked at 5.9 billion tests taken on 237,213 mobile devices across the U.S.

These tests showed that T-Mobile finishing with the fastest average 4G LTE download speed of 19.42Mbps. Verizon came in second with an average LTE download speed of 17.77Mbps, AT&T finished third with 13.27Mbps, and Sprint came in fourth with 12.02Mbps.

T-Mobile also won the 4G LTE availability category, with T-Mo customers able to find an LTE connection 93.14 percent of the time. Other categories won by T-Mobile include average 3G download speed (3.46Mbps), average overall download speeds (18.31Mbps), and average 3G latency (109.41ms).

The only category that T-Mobile didn’t win in OpenSignal’s report is average 4G LTE latency. That award was won by AT&T, which posted an average LTE latency of 58.29ms. T-Mobile wasn’t far behind, though, posting an average LTE latency of 59.74ms.

OpenSignal also shared a regional performance chart that shows which carriers did best in 4G LTE availability, 4G LTE download speed, and 4G LTE latency in major metro areas across the country. You can check the whole thing out right here.

T-Mobile continued work on expanding its 4G LTE coverage in 2017, ending the year with an LTE network that covered 322 million people. T-Mo will continue to improve its 4G LTE coverage in 2018 by rolling out more 600MHz LTE coverage to improve the reach of its LTE coverage. 600MHz LTE is available in 586 cities across the U.S.

    “T-Mobile also won the 4G LTE availability category, with T-Mo customers able to find an LTE connection 93.14 percent of the time.”

    Does this mean when able to connect to Tmobile network? Or when the phone is on? I’m curious how the measure is computed.

      from the source: “This metric shows the proportion of time OpenSignal users have an LTE connection available to them on each operator’s network. It’s a measure of how often users can access a 4G network rather than a measure of geographic or population coverage.”

      It’s (arguably) better than a coverage map alone, since it represents where and when users are actually engaging with the network, rather than empty-space-coverage in areas that few if any users go to.

        Yeah, though its debatable – there’s reason to believe that people who use OpenSignal may be different than those that don’t; it wouldn’t surprise me if they skewed towards a younger, more tech-savvy crowd, and those people may be more likely to live in some areas than others.

        Of course, “average” availability doesn’t really matter to most people, since we tend to live/work and even travel within a few locations in a year. Having great coverage overall is pointless if there’s no coverage where you are; at the same time, I had few issues with T-Mobile 7 years ago, even when their network was a lot smaller.

        So the other way to read it is that people with t-mobile are afraid to venture outside major cities cause they know the coverage sucks, so statistically they hang on the network longer since they stay within city/coverage boarders, while ATT and Verizon customers are not afraid to travel all over the map and occasionally end up loosing signal here and there, so % wise they will spend less time connected to the network due to occasional drops in rural or middle of nowhere places.

    It sure would be nice if 3x carrier aggregation was far more widely deployed!!!

  • Turb0wned

    To bad speed doesn’t equal coverage.

    • Romdude

      It’s all a matter of point of view, from yours maybe, not mine, coverage in my area is good and faster than all 3 other carriers.

      Actually T-Mobile won 4G coverage as well.

    It’s really hard to read between the lines with Open Signal performance outside the major metro areas. Reading the tea-leaves I’d deduce that Verizon still generally has a rural advantage due to longer range from towers, but I’d also suspect that T-Mobile’s numbers in rural areas are being artificially depressed by a lot of people still trying to access the network on 1900 and 2100MHz frequencies only. But unless Open Signal can get a lot more people to use their app I feel it’s going to be of limited use.
