T-Mobile announced it was able to aggregate three channels of mid-band 5G spectrum, reaching speeds over 3 Gbps on its standalone 5G network.

It’s the first time the test has ever been done with a commercial device (Samsung Galaxy S22 powered by Snapdragon 8 Gen 1 Mobile Platform with Snapdragon X65 Modem-RF System) on a live production network.

“Only T-Mobile is delivering a nationwide standalone 5G network to customers today, and we’re blazing a trail with new performance-boosting capabilities that generate incredible speeds and deliver on our vision to create the highest capacity network in the country,” said Neville Ray, President of Technology at T-Mobile.

5G Carrier Aggregation (NR CA) allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance. T-Mobile merged three 5G channels – two channels of 2.5 GHz Ultra Capacity 5G and one channel of 1900 MHz spectrum – creating an effective 210 MHz 5G channel.

NR CA is live in parts of T-Mobile’s network, combining two 2.5 GHz 5G channels for greater speeds, performance and capacity. Customers with Samsung Galaxy S22 will be among the first to experience a third 1900 MHz 5G channel later this year.
