T-Mobile US 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.
The achievement marks a new speed record in North America using sub-6 GHz spectrum.
UL Tx switching enables seamless switching and a combination of different frequencies, effectively creating more uplink capacity and higher uplink speed.
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 AirScale portfolio and a mobile test smartphone powered by a flagship Snapdragon Modem-RF system from Qualcomm Technologies.
“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.”
“We are proud to work with our long-term partner, T-Mobile on this important and significant achievement that will enhance the uplink speed and capacity of their 5G network – the largest and fastest in the U.S. – and deliver an even better experience for customers,” said Tommi Uitto, President of Mobile Networks at Nokia. “By working closely and collaboratively with our partners we can push the boundaries of what is possible with 5G.”
