T-Mobile is expanding support for the L4S standard, a technology that reduces latency and improves the quality of high-priority internet traffic on its 5G network, making services like video calls and cloud gaming smoother without requiring special devices or plans. This marks T-Mobile as the first US wireless provider to implement L4S, which helps manage network congestion more efficiently and is already deployed in several cities on their 5G Advanced network.
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.
