RootMetrics 5G Report Shows Verizon Surpassing 1 Gbps in Chicago while Sprint Has Coverage Advantage In Atlanta, Chicago, and Dallas

New mobile performance report shows that all carriers delivered impressive speeds on 5G despite generally low 5G availability in all three cities

BELLEVUE, Wash. -RootMetrics by IHS Markit released the second in its series of 5G First Look Reports, discussing 5G performance by US carriers AT&T, Sprint, T-Mobile, and Verizon in Atlanta, Chicago, and Dallas. The new report shows that each carrier delivered impressive 5G speeds and reliability, although connecting to 5G could prove challenging in the early stages of deployments.

Key takeaways

  • With the exception of Sprint’s results, the vast majority of RootMetrics download tests were recorded on non-5G mode in each city.
  • Sprint had more tests recorded on 5G than the other carriers, and Sprint’s 5G network in Chicago is particularly widespread; the carrier’s 5G coverage was comparable to its LTE coverage in the city.
  • Given the generally low 5G availability rates for AT&T, T-Mobile, and Verizon at the time of 5G launches, questions remain about how often users will actually connect to 5G.
  • AT&T delivered the fastest 5G median download speed among all carriers across all three cities, at 256.1 Mbps in Dallas.
  • Verizon was the only carrier to deliver a 5G maximum download speed faster than 1 Gbps, delivering a speed of 1.1 Gbps in Chicago.

During the nascent stages of 5G rollouts, connecting to 5G at relatively low availability rates is not necessarily a surprise. Mobile network operators often choose to launch 5G only in certain areas of a city and/or may target very specific audience segments, such as enterprise customers. RootMetrics testing has shown that it can often take months or even a few years for network technologies to realize their full potential for end users, but the company does expect 5G service to become more prevalent as the networks continue to make upgrades and as 5G networks mature over time.

Carrier highlights

AT&T delivers strong 5G results in Dallas on limited 5G footprint.

RootMetrics was able to record 5G results for AT&T only in Dallas, where it connected to AT&T’s 5G network during just 2.6% of its download tests. However, the carrier’s 5G speeds in the city were impressive. AT&T’s 5G median download speed of 256.1 Mbps in Dallas was the fastest among all carriers across all three cities. At 256.1 Mbps, an end user could download a 600MB video in less than 20 seconds, a dramatic improvement from the roughly 4 minutes it would take to download the same video at the carrier’s non-5G mode median download speed of 19.4 Mbps in the same city.

Sprint was the only carrier with meaningful 5G availability in all three cities, but results were mixed in Dallas.

Sprint’s 5G network was far more widespread than those of the other carriers, with the carrier’s 5G availability rates ranging from its lowest rate of 24.9% in Dallas to a high of 51.4% in Atlanta. In contrast, the highest 5G availability rate recorded by any other carrier across the three cities was Verizon’s rate of 7.1% in Chicago. Sprint’s speeds were much faster on 5G compared to non-5G mode in both Atlanta and Chicago, though the carrier’s most impressive results were found in Chicago, where the carrier registered a 5G availability rate of 32.2%. At Sprint’s 5G median download speed of 123.5 Mbps in Chicago, it would take less than 40 seconds to download a 600MB video. In contrast, downloading the same video at the carrier’s non-5G mode speed of 26.1 Mbps in Chicago would take closer to 3 minutes.

T-Mobile shows impressive 5G maximum download speed in Atlanta.

T-Mobile was on 5G during RootMetrics tests at low rates in Atlanta (3.1%) and Dallas (1.3%), and no 5G results were recorded for T-Mobile in Chicago. T-Mobile’s 5G median download speeds in both Atlanta and Dallas were quite slow in general and slower than its non-5G mode speeds in each city. Despite the carrier’s slow 5G median speeds, the carrier’s 5G maximum download speed of 257.7 Mbps in Atlanta points to a promising future for the carrier’s 5G experience. While T-Mobile’s 5G availability was limited at launch, the carrier’s non-5G mode results were strong in both cities, suggesting that T-Mobile subscribers should experience fast speeds and excellent reliability even when 5G isn’t available.

Verizon shows promising 5G results in Chicago.

RootMetrics recorded results on Verizon’s 5G network in only one of the three cities tested: Chicago. Despite Verizon’s 5G available rate of 7.1% in Chicago, the carrier’s 5G speeds were outstanding. Verizon was the only carrier in any city to deliver a 5G maximum download speed faster than 1.0 Gbps (1.1 Gbps), and the carrier’s 5G median download speed of 146.1 Mbps was over four times faster than its non-5G mode median download speed. At 146.1 Mbps, Verizon users could download a 600MB video in about 34 seconds in Chicago, a notable improvement from the 2.3 minutes it would take to download the same video at the carrier’s non-5G mode speed. While Verizon’s 5G footprint in Chicago was small, the carrier’s non-5G mode results in the city were also quite strong, with fast non-5G mode speeds and excellent reliability, all of which lay the foundation for a strong 5G experience going forward.

“The 5G era in the US has begun, and the speeds we found during our early testing in Atlanta, Chicago, and Dallas were quite promising. Verizon in particular stood out with its 5G maximum download speed of 1.1 Gbps in Chicago, which was the fastest speed we’ve ever recorded in the US on any network technology. While the speeds we recorded during initial 5G testing showed potential for the future of 5G, our results also suggest that there’s still work to be done before consumers experience the incredibly fast speeds of 5G on a daily basis,” said Francis Sideco, vice president, technology at IHS Markit. “With the exception of Sprint, the 5G availability rates we found were low across the board. That said, the carriers are making near-constant network upgrades across the country, and we expect to see more consistently fast speeds on 5G going forward. We are continuing to test 5G networks across the US to show consumers and enterprises alike how 5G performance evolves over time.”

How RootMetrics tests

RootMetrics by IHS Markit combines scientific data with real-world mobile performance insights to provide consumers with an independent view of each network’s performance where they live, work and play. RootMetrics measured 5G performance indoors and outdoors where people most often use their smartphones in and around Atlanta, Chicago, and Dallas: tourist areas, business districts, and other high-population areas. To paint a comprehensive picture of real-world 5G performance, RootMetrics also tested 5G while driving in urban and suburban areas in all three cities.

In the early phases of 5G deployments when the technology typically isn’t rolled out by carriers across an entire city, the RootMetrics scientific testing methodology is the only way to truly characterize the end-user’s real-world 5G experience. While crowdsourced 5G studies often base conclusions on small and/or biased samples limited to specific locations where users choose to submit crowd results, the RootMetrics randomized spatial sampling techniques ensure 5G performance is accurately portrayed from the consumer’s perspective across an entire test location and at different times of the day and night.

From July 24 to August 10, 2019, RootMetrics scouters drove 522 miles, visited 40 indoor locations and collected more than 20,000 test samples of 5G performance across Atlanta, Chicago, and Dallas. All tests were conducted using unmodified, off-the-shelf Samsung Galaxy S10 5G and LG V50 ThinQ 5G smartphones purchased from operator stores.
