Up until now, Verizon has ridden its millimeter wave-based 5G coverage to the top of the list for 5G network efficiency. But as networks continue to evolve, were beginning to see some changes, highlighted by the most current performance report from network tester Ookla which covers the last three months of 2020. AT&T 5G is the reigning champ throughout the fourth quarter of last year, according to Ookla, which shocked us practically as much as its probably shocked you. Thats a quite large shift, specifically since Ookla rated Verizon as the best-performing 5G network as recently as the 3rd quarter of 2020, when the carriers speed score was a lofty 792.5. That dwarfed AT&Ts next finest score of 65.22. For the 4th quarter, however, AT&Ts 5G speed rating rose to 75.59, while Verizon plunged to 67.07. The huge drop in Verizons rating can be credited to Verizons broader rollout of its 5G network to more markets. In October, with the launch of the iPhone 12, Big Red moved beyond mmWave 5G to consist of sub 6Hz spectrum in its network. That kind of 5G covers more people– Verizon now says its 5G network reaches 230 million people– but its also much slower than mmWave. And more individuals getting slower speed on a network will drive down the speed score, according to Ookla.( Image credit: Ookla) With this overall drop in speed, Verizon now sits at the bottom of the 5G pile behind T-Mobile and Sprint (both of which were determined independently in spite of their 2020 merger). In terms of general efficiency– LTE and 5G– Ookla ranks AT&T No. 1 for the 8th successive quarter. T-Mobile, Sprint and Verizon complete the newest rankings.It stays to be seen if AT&T and T-Mobile will experience comparable reductions in their ratings as a growing number of people sign up with the 5G transformation. 2021 is seeming a fascinating year when it pertains to carrier 5G performance.Todays finest Apple iPhone 12 dealsUnlimited minsUnlimitedtexts12GBdataCalls: Calls to MX & & CA includedTexts: Messaging to MX & & CA includedData: (slowed to 128kbps speeds) Unlimited minsUnlimitedtexts8GBdataCalls: Calls to MX & & CA includedTexts: Messaging to MX & & CA includedData: (slowed to 128kbps speeds) Unlimited minsUnlimitedtexts3GBdataCalls: Calls to MX & & CA includedTexts: Messaging to MX & & CA includedData: (slowed to 128kbps speeds).
