T-Mobile is bringing low-latency tech to 5G for the first time
UNITED STATES, JUL 21 – T-Mobile’s L4S rollout improves latency and reduces packet loss on 5G Advanced, enhancing video calls, cloud gaming, and extended reality without device upgrades, company says.
- On July 21, 2025, T-Mobile US Inc. announced the deployment of a new advanced network feature designed to minimize delays and data loss while increasing throughput capacity across its 5G network in the United States.
- This deployment follows persistent network congestion issues that cause lag and buffering even on high-speed 5G, and T-Mobile aims to reduce these delays with L4S.
- L4S prioritizes critical data packets to enable real-time responsiveness under heavy traffic, improving applications like video calls, cloud gaming, and remote driving without requiring device upgrades.
- John Saw, T-Mobile’s CTO, highlighted that L4S provides reliable real-time performance with minimal delays and packet loss, resulting in clear visuals, smooth frame rates, and a noticeable decrease in motion sickness.
- T-Mobile's rollout, starting in select markets and expanding nationwide, positions it as the first U.S. carrier to scale L4S wirelessly and may prompt industry-wide focus on quality of experience over speed alone.
