T-Mobile US said 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, here the Samsung Galaxy S22 powered by Snapdragon 8 Gen 1 Mobile Platform with Snapdragon X65 Modem-RF System), on a live production network, the company said.
5G Carrier Aggregation (New Radio or NR CA) allows T-Mobile to combine multiple 5G channels (or carriers) to deliver greater speed and performance. In this test, the carrier 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.
The achievement is only possible with standalone 5G architecture (SA) and is just the latest in a series of important SA 5G milestones for T-Mobile. The carrier said it was the first in the world to launch a nationwide SA 5G network nearly two years ago. The carrier began lighting up Voice over 5G (VoNR) this month so that all services can run on 5G. By removing the need for an underlying LTE network and 4G core, 5G will be able to reach its true future potential with incredibly fast speeds, real-time responsiveness and massive connectivity, the company mentioned.
NR CA is live in parts of T-Mobile’s network today, combining two 2.5 GHz 5G channels for greater speeds, performance and capacity. Customers with the Samsung Galaxy S22 will be among the first to experience a third 1900 MHz 5G channel later this year. This functionality will expand across the carrier’s network and to additional devices in the near future.
T-Mobile US was the first in the world to launch a nationwide SA 5G network nearly two years ago and has been driving toward a true 5G-only experience for customers ever since. Just this month the Un-carrier began deploying Voice over 5G (VoNR) so ALLvoice services can run on 5G. By removing the need for an underlying 4G LTE network and 4G core, 5G will be able to reach its true future potential with incredibly fast speeds, real-time responsiveness and massive connectivity. The carrier’s 5G network covers 315 million people across 1.8 million square miles. 225 million people nationwide are covered with super-fast Ultra Capacity 5G, and T-Mobile expects to cover 260 million in 2022 and 300 million next year. It also has the fastest 5G network, according to Ookla speed tests in Q4 2021:
Note that neither Verizon or AT&T have deployed 5G SA core networks with no future dates specified.
