T‑Mobile Shatters World Record for 5G Uplink Speed

BELLEVUE, Wash. — The Un-carrier just went plaid! T-Mobile (NASDAQ: TMUS) today announced it broke another world record with its 5G standalone (SA) network, leveraging an emerging feature called New Radio Dual Connectivity (5G DC). With 5G DC, the Un-carrier was able to massively increase uplink throughput and capacity, reaching peak speeds of 2.2 Gbps — that’s the fastest recorded anywhere in the world — and demonstrates the technology’s potential to create serious efficiencies in how data is transmitted from devices to the network.  

5G DC enables the Un-carrier to aggregate 2.5 GHz and mmWave spectrum, allowing for an insane boost to uplink throughput and capacity. In this test, T-Mobile was able to allocate 60% of the mmWave radio resources for uplink where previous use cases typically allowed up to 20%. Completed on T-Mobile’s 5G SA production network in SoFi Stadium in Southern California with equipment and 5G DC solution from Ericsson and a mobile test smartphone powered by a flagship Snapdragon® X80 5G Modem-RF System from Qualcomm Technologies, Inc., this test changes the game for providers looking to offer customers and businesses the best experience possible at crowded events.

“With 5G DC, T-Mobile is pushing the boundaries of what’s possible to create better experiences in the places that matter most to our customers,” said Ulf Ewaldsson, President of Technology at T-Mobile. “This accomplishment is a testament to the network we’ve built over the last five years and our ability to deliver unparalleled capabilities that extend beyond the devices in our pockets.”

For those in the know, download speeds typically reign as the top network performance metric, but with recent strides in uplink capabilities and increasingly demanding tasks, upload speed is becoming more important than ever, especially for live events, mobile gaming and extended reality applications.

Because of this, SoFi Stadium served as the perfect test site for 5G DC. Every year, millions of people flock to the stadium for the latest football game or to catch their favorite artists in concert. Naturally, all these people want to post, livestream and share their experiences in real-time, which can sometimes be a challenge at crowded events with limited capacity. Not to mention broadcast crews who need to upload high-definition content to production teams in real-time for those watching at home. With 5G DC and T-Mobile, all of this gets done faster than ever, alleviating posting FOMO and production crew headaches. Problem solved!

Mårten Lerner, Head of Product Area Networks at Ericsson, also said: "High uplink speeds are essential for delivering immersive experiences and reliable 5G connectivity. This mirrors one of our key objectives with the recent launch of Ericsson 5G Advanced, which is to elevate user experience by enhancing network performance for more interactive applications. This 5G uplink speed milestone, achieved with T-Mobile and Qualcomm, underscores our commitment to taking user experience to unprecedented levels."

“We are incredibly proud to achieve yet another world record with T-Mobile. This groundbreaking achievement shows what could be possible with 5G DC and how it can bring new, unparalleled experiences to consumers, especially at large events like football games and concerts,” said Sunil Patil, Vice President, Product Management, Qualcomm Technologies, Inc. “We will continue our close collaboration with global innovators like T-Mobile and Ericsson to push the boundaries and unlock the full potential of 5G.”

T-Mobile is the leader in 5G, delivering America’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 than 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 mid-band 5G offerings from the Un-carrier’s closest competitors.
