BELLEVUE, Wash. — January 4, 2024 —The Un-carrier is picking up speed. T-Mobile (NASDAQ: TMUS) today announced 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, Inc., the Un-carrier reached mind-blowing speeds above 3.6 Gbps in the test – fast enough to download a two-hour HD movie in less than 7 seconds!

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

5G carrier aggregation allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance. In this test, the Un-carrier 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 effective 245 MHz of aggregated 5G channels. 

T-Mobile is the leader in 5G, delivering the country’s largest, fastest and most awarded 5G network. The Un-carrier’s 5G network covers more than 330 million people across two million square miles — more coverage area than AT&T and Verizon combined. 300 million people nationwide are covered by T-Mobile’s super-fast Ultra Capacity 5G with over 2x more square miles of coverage than similar offerings from the Un-carrier’s closest competitors.
