DT’s US opco claims world first 6-carrier aggregation call in sub-6GHz

In the test, it reached speeds of 3.6Gbps

DT’s American subsidiary, T-Mobile US, says it achieved the world’s first six-carrier aggregation call using sub-6 GHz spectrum on its live production 5G network. Working with Ericsson and Qualcomm Technologies, it reached above 3.6 Gbps in the test.

5G carrier aggregation allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance.

In this test, T-Mobile merged six 5G channels of mid-band spectrum – two channels of 2.5 GHz Ultra Capacity 5G, two channels of PCS spectrum and two channels of AWS spectrum – creating an aggregated 245 MHz 5G channels. 

Pushing the boundaries

Ulf Ewaldsson, President of Technology at T-Mobile, claims, “We are pushing the boundaries of wireless technology to offer our customers the best experience possible.

“With the first and largest 5G standalone network in the country, T-Mobile is the only mobile provider serving 10s of millions of customers to unleash new capabilities like 5G carrier aggregation nationwide, and I am so incredibly proud of our team for leading the way.”  

T-Mobile US’ 5G network covers more than 330 million people over 2 million square miles which is says is a wider 5G coverage area than AT&T and Verizon combined.
