T-Mobile has worked with Nokia and Qualcomm to reach uplink speeds topping 200 Mbps in a 5G data call leveraging uplink carrier aggregation – the first-ever on a live commercial 5G standalone network in the U.S.
Increased uplink speeds allow operators to transmit more data from customer devices at a quicker rate, enhancing applications like video livestreaming/calling, gaming and Extended Reality (XR).

T-Mobile has achieved speed of 207 Mbps in the test in a test smartphone powered by Snapdragon 5G Modem-RF System from Qualcomm Technologies. This is the fastest ever speed recorded using sub-6 GHz spectrum.

“T-Mobile has led the industry with 5G standalone since 2020, and we’re continuing to drive breakthroughs that advance 5G technology around the globe,” said Ulf Ewaldsson, President of Technology at T-Mobile.

5G carrier aggregation allows T-Mobile to combine multiple channels (or carriers) to deliver greater speed and performance. T-Mobile merged two 5G channels of mid-band spectrum – 2.5 GHz Ultra Capacity 5G and 1900 MHz.

Customers with compatible devices will be able to utilize UL 5G carrier aggregation early next year when T-Mobile begins rolling it out.

T-Mobile’s 5G network covers 326 million people across 2 million square miles – more than AT&T and Verizon combined. 275 million people are covered by T-Mobile’s Ultra Capacity 5G, and the Un-carrier plans to reach 300 million people with Ultra Capacity – nearly everyone in the country – this year.
