"T-Mobile Breaks 5G Uplink Speed Record with 'Superhighway' Expansion"
T-Mobile has achieved a record-breaking uplink speed test of 345 Mbps on its 5G SA network using a novel network technology called Uplink Transmit (UL Tx) switching, which is expected to expand its "5G superhighway" with faster lanes and spare capacity. This technology leverages carrier aggregation and SU-MIMO to deliver uplink speeds 25% faster than previous records. The improved uplink performance will benefit content creators, remote work, gaming, and AR/VR experiences, but there's no specific timeline for its implementation for T-Mobile customers.
