Learn more about L4S 

Dive into our white papers and publications

The eBook highlights how latency, not just speed, now defines internet performance for real-time apps. Traditional TCP and AQM struggle with congestion, but L4S uses ECN and dual-queue AQM to cut delays, prevent packet loss, and keep high throughput. With updates to devices and networks, L4S can lower latency below 10 ms, greatly improving Quality of Experience (QoE).

The white paper shows how Wi-Fi 7 with 320 MHz channels, 4K QAM, and MLO boosts throughput, while L4S cuts latency by preventing congestion with ECN feedback. Trials in Excentis’ Wi-Fi House prove that combining them delivers faster, more stable, low-latency connectivity, ideal for gaming, AR/VR, and streaming.

The Excentis–Nokia Bell Labs study shows L4S on Wi-Fi 6/7 can reduce latency by up to 90% (single client) and 70% (multi-client) using DualQ AQM and optimized WMM. Tests highlight big gains for gaming and video calls, with L4S outperforming Wi-Fi 7 in latency, though challenges like media delays and device settings remain.
