T-Mobile announced its latest achievement in 5G performance, reaching record downlink speeds using Nokia’s cutting-edge 5G RAN equipment.
The first test used a commercially available Samsung Galaxy S25 with the Snapdragon® X80 5G Modem-RF System running test software, leveraging T-Mobile’s industry-leading 5G network to reach downlink speeds of 4.3 Gbps in real-world conditions.
In a second test, offering a glimpse into the next evolution of 5G Advanced, T-Mobile pushed the boundaries even further by using the brand-new Qualcomm X85 5G Modem-RF on a mobile test device, achieving peak speeds of 6.3 Gbps.
Both tests combined low-band and mid-band spectrum on T-Mobile’s 5G Standalone (5G SA) production network, demonstrating ultra-fast performance.
“With 6-Carrier Aggregation, we’re not just adding another feather to our cap, we’re accelerating the future of 5G Advanced,” said Ulf Ewaldsson, President of Technology, T-Mobile. “This milestone isn’t just about speed; it’s about building a network that delivers exactly what our customers need, unparalleled performance, reliability and innovation.”
T-Mobile’s record-breaking speeds were achieved in real-world field conditions on the Un-carrier's production network, showcasing both reliability and practicality.
By leveraging its unique mix of owned spectrum bands (C-Band, 2.5GHz, PCS, AWS and 600MHz), T-Mobile has delivered results that are not just impressive but grounded in real world conditions, laying the foundation for future innovation.
“This achievement, in collaboration with our long-standing partners, T-Mobile and Qualcomm Technologies, reflects Nokia’s commitment to developing 5G Advanced solutions with a strong focus on the areas that matter the most to our customers,” said Tommi Uitto, President of Mobile Networks at Nokia. “By combining our Massive MIMO radios, advanced beamforming techniques, high-order Carrier Aggregation, and high-order modulation, we have demonstrated the key building blocks of premium 5G Advanced performance, now successfully validated in a live customer network.”
“We are excited to have contributed to this achievement, utilizing our Qualcomm X85 Modem-RF to push the boundaries of 5G Advanced downlink speeds,” said Durga Malladi, Senior Vice President and General Manager, Technology Planning and Edge Solutions at Qualcomm Technologies, Inc. “This collaboration with T-Mobile and Nokia highlights our commitment to driving innovation and setting new benchmarks in wireless performance.”
