Elisa, Nokia showcase 5G-Advanced L4S Tech in the Nordics

Nokia and Elisa have successfully demonstrated a new technology feature in 5G Advanced standalone networks called Low Latency, Low Loss, Scalable Throughput or L4S.

L4S helps 5G network users stream content seamlessly in congested radio network environments such as at concerts or sports events. In 2022, L4S was adopted in 3GPP 5G-Advanced Release 18 to support Extended Reality (XR) over 5G RAN networks. The successful trial, which was first in the Nordics and held at the Nokia Arena in Tampere, Finland, utilized Nokia’s 5G AirScale portfolio over Elisa’s live 5G standalone network.

During the trial, two smartphones were used in a congested network to play the same footage. However, only one of these phones utilized L4S technology. The non-L4S enabled device would halt immediately when attempting to load the streaming content. The L4S content streamed instantly. Both companies worked with streaming company, Kepit Systems and Immersal, a leading metaverse technology provider for augmented reality (AR) real-time applications to test different metaverse based use cases.

Nokia’s Network as Code solution, which enables applications to dynamically program the network to optimize the performance and user experience could offer L4S technology to drive new business value for mobile operators.

Kalle Lehtinen, CTO at Elisa, said: “Elisa is a pioneer in introducing cutting edge technology to enhance the experience of our customers. In this successful trial with Nokia, we have demonstrated how we are continuing to push the boundaries of our 5G network and deliver scalable, premium services.

Ari Kynäslahti, Head of Strategy and Technology at Nokia Mobile Networks, said: “5G Advanced will usher in a host of incredible features that will elevate the 5G network to its fullest and richest capabilities. The L4S feature is really just beginning of what will be possible but will enhance the experience of people at crowded events streaming content. This is also another successful project in our long-standing and well-established relationship with Elisa and I look forward to continuing this positive collaboration.”
