T-Mobile, the telecommunications giant, recently established a new record by attaining a 345 Mbps uplink speed test on its standalone (SA) 5G network. The record-breaking speed was achieved using a pioneering network technology known as Uplink Transmit (UL Tx).
The company describes UL Tx as an innovative technology, enabling smooth switching and merging of various frequencies, effectively generating more uplink capacity and superior uplink speed. It can be likened to the addition of faster lanes with extra capacity on a superhighway, allowing traffic to move more swiftly than before.
T-Mobile details the impressive test result was attained by harnessing the power of two strategies. Firstly, it employed carrier aggregation, which amalgamates different channels of spectrum to provide more capacity and speed. Secondly, it used Single-user MIMO (SU-MIMO), a technology that permits your phone to transmit multiple data streams simultaneously.
Essentially, these strategies enabled T-Mobile to beat its previous uplink speed record of 275 Mbps by 25%. The company anticipates the innovative technology will drastically alter how data is transmitted from mobile devices to the network, enhancing not only upload speed but also performance in content creation, remote working, gaming, and virtual reality.
For the test, T-Mobile utilized state-of-the-art equipment from Nokia's next-generation AirScale portfolio in combination with a test smartphone powered by Qualcomm Technologies' Snapdragon Modem-RF system.
Addressing this development, Durga Malladi, the Senior Vice President and General Manager of Technology Planning & Edge Solutions at Qualcomm Technologies, voiced that the switched uplink would meet the increasing demand for upload-intensive user applications such as smartphones, fixed wireless access, mobile broadband, and more.
T-Mobile has not yet revealed when the UL Tx technology will be available to its customers.
