T-Mobile Reaches Speeds of 3.3 Gbps on Its 5G Standalone Network

T-Mobile has announced the world's first four-carrier aggregation data call on a commercial device, combining four channels of mid-band spectrum to hit peak speeds topping 3.3 Gbps.

The company aggregated four channels of mid-band spectrum on its 5G standalone (5G SA) network with the Samsung Galaxy S23. Notably, Apple plans to introduce support for 5G standalone with iOS 16.4, currently being tested by developers.

T-Mobile also announced the expansion of VoNR to four new cities: Cincinnati, OH; New Orleans, LA; New York, NY; and Seattle, WA.


"We are working with industry leaders around the globe to move the 5G ecosystem forward for the benefit of wireless customers everywhere," said Neville Ray, President of Technology at T-Mobile. "With the most advanced 5G network in the world, T-Mobile is at the forefront of wireless innovation, spearheading new capabilities so we can continue raising the performance bar and enable future transformative applications that require a seamless and robust 5G connection."

Four-Carrier Aggregation
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 four 5G channels of mid-band spectrum – two channels of 2.5 GHz Ultra Capacity 5G and two channels of 1900 MHz spectrum – creating an effective 225 MHz 5G channel. That's like taking four separate highways and turning them into a massive superhighway where traffic can zoom faster than before. Customers with the Samsung Galaxy S23 will be among the first to experience four-carrier aggregation later this year with more devices to follow.

VoNR
With VoNR, T-Mobile is moving voice traffic to 5G so customers stay consistently connected to 5G. In the near-term, customers connected to VoNR may notice slightly faster call set-up times, meaning less delay between the time they dial a number and when the phone starts ringing. But VoNR is about more than just a better calling experience. Most importantly, VoNR brings T-Mobile one step closer to truly unleashing its 5G SA network because it enables advanced capabilities like network slicing that rely on a continuous connection to a 5G core. Today VoNR is now live in six cities – Cincinnati, OH; New Orleans, LA; New York, NY; Portland, OR; Salt Lake City, UT; and Seattle, WA – and the Un-carrier will expand this technology to additional cities covering more than 100 million people in the coming months.
