T-Mobile (NASDAQ: TMUS) today announced it achieved record-breaking uplink speeds of 345 Mbps on its 5G standalone (SA) network in a recent test leveraging a new feature called UL Tx switching. That’s the fastest ever recorded in North America using sub-6 GHz spectrum and it demonstrates the technology’s potential to revolutionize the way data is transmitted from mobile devices to the network.\n\n\nUL Tx switching is a groundbreaking technology that enables seamless switching and a combination of different frequencies, effectively creating more uplink capacity and higher uplink speed. In other words, it's like taking the 5G superhighway and adding new faster lanes with spare capacity for traffic to zoom faster than ever. This test combined the power of carrier aggregation (combining different channels of spectrum for more capacity and speed) and SU-MIMO (single user multiple input, multiple output – which means it gives your phone the ability to send multiple data streams at the same time) to deliver uplink speeds 25% faster than T-Mobile’s previous record of 275 Mbps. The test used equipment from Nokia’s cutting-edge next-generation AirScale portfolio and a mobile test smartphone powered by a flagship Snapdragon® Modem-RF system from Qualcomm Technologies, Inc.\n\n\n“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 implore our partners around the globe to build the capability into the 5G ecosystem moving forward.”\n\n\nT-Mobile’s 5G network has delivered massive performance enhancements for customers primarily in terms of download speeds, but the industry has only begun scratching the surface when it comes to uploads. Greater uplink speeds are critical for customers when it comes to content creation and sharing, remote work and collaboration, gaming, emergin...
