Vodafone & Nokia Trial L4S: Cutting Internet Lag by 94% on Live FTTH Network
Vodafone and Nokia have successfully trialled a new internet technology, L4S (Low Latency, Low Loss, Scalable throughput), on a live commercial fibre broadband network in Istanbul. The trial, conducted on Vodafone Türkiye's Fibre to the Home (FTTH) network, has shown promising results in reducing internet delays.
The technology, developed by Nokia Bell Labs, was deployed end-to-end on a full FTTH network for the first time in the world. It significantly reduced round-trip delay, from 220 milliseconds to 4.7 milliseconds, while using video conferencing and cloud gaming applications. This resulted in a lag reduction of up to 94 per cent.
L4S works by tackling data packet congestion in network buffers, a major cause of lag in online experiences. It reduces queuing delays, enabling smoother online gaming, video calls, and other real-time applications. Vodafone will now conduct further tests before considering a wider rollout of the technology across its European markets.
The successful trial of L4S technology on Vodafone Türkiye's FTTH network in Istanbul paves the way for potential improvements in internet speed and reliability across Vodafone's European markets. The technology's ability to reduce lag significantly could enhance online experiences for customers.
