T-Mobile has reached a new 5G milestone, recording the fastest uplink speed to date on a 5G standalone network in North America.
In recent testing, T-Mobile achieved an upload speed of 345 Mbps using sub-6 GHz spectrum, surpassing its previous record of 275 Mbps.
This breakthrough was enabled by a technique called UL Tx switching, which allows devices to switch seamlessly between different frequencies to increase capacity and throughput. When combined with carrier aggregation and SU-MIMO, UL Tx switching creates additional data “lanes,” allowing uploads to travel faster and more efficiently between devices and the network.
“This achievement is a testament to our relentless pursuit of innovation and our commitment to delivering an even better network experience to our customers,” said Ulf Ewaldsson, President of Technology at T-Mobile.
“Uplink transmit switching has the potential to significantly boost upload speeds and capacity, and we encourage industry partners worldwide to incorporate this capability into the 5G ecosystem moving forward.”
Higher upload speeds are increasingly important as 5G supports more data-intensive use cases such as content creation, remote collaboration, cloud gaming, and extended reality (XR). T-Mobile collaborated with Qualcomm and Nokia on the test and technology integration.
“We are proud to work with T-Mobile to achieve another important 5G milestone,” said Durga Malladi, Senior Vice President and General Manager, Technology Planning & Edge Solutions at Qualcomm. “Switched uplink can unlock remarkable upload speeds by intelligently and dynamically using TDD and FDD spectrum in devices. This advancement will serve the growing demand from upload-heavy applications and services across smartphones, fixed wireless access, mobile broadband, and more.”
T-Mobile’s 5G network covers more than 330 million people across two million square miles, and over 300 million people nationwide have access to its mid-band Ultra Capacity 5G.
“We are proud to work with our long-term partner, T-Mobile, on this important achievement that enhances uplink speed and capacity on what is already the largest and fastest 5G network in the U.S., delivering a better experience for customers,” said Tommi Uitto, President of Mobile Networks at Nokia.
“By collaborating closely with partners, we can continue pushing the boundaries of what 5G makes possible.”
