T-Mobile Achieves Record-Breaking 5G Milestone with Six-Carrier Aggregation Call

T-Mobile US has set a global benchmark by executing the world’s first six-carrier aggregation call using sub-6 GHz spectrum on its live production 5G network.

During the test phase, T-Mobile achieved unprecedented speeds exceeding 3.6 Gbps, a rate so rapid that it could download a two-hour high-definition movie in less than seven seconds.

Ulf Ewaldsson, President of Technology at T-Mobile, expressed pride in the team’s accomplishment, stating, “With the first and largest 5G standalone network in the country, T-Mobile is the only mobile provider serving tens of millions of customers to unleash new capabilities like 5G carrier aggregation nationwide.”

The utilization of 5G carrier aggregation technology empowers T-Mobile to merge multiple 5G channels, or carriers, enabling enhanced speed and performance. In this specific test, the Un-carrier amalgamated six 5G channels comprising mid-band spectrum. This aggregation included two channels of 2.5 GHz Ultra Capacity 5G, two channels of PCS spectrum, and two channels of AWS spectrum, effectively creating a consolidated 245 MHz of 5G channels.

T-Mobile’s 5G network currently spans across more than 330 million individuals within two million square miles. Remarkably, this coverage area surpasses the combined coverage of AT&T and Verizon. Furthermore, T-Mobile’s Ultra Capacity 5G, providing high-speed connectivity to 300 million people nationwide, offers over double the coverage area compared to similar offerings from its closest competitors.
