Elisa and Nokia said they are the first companies in the Nordic region to showcase 5G-Advanced Low Loss, Low Latency, Scalable Throughput (L4S) technology for live uses in congested network environments. They held a successful trial at the Nokia Arena in Tampere using Nokia’s AirScale portfolio on Elisa’s live 5G Standalone network. 

The 3GPP 5G-Advanced Release 18 adopted an L4S feature in 2022 to support Extended Reality (XR) to enable smooth streaming of live content in congested network environments, suitable for sports events and concerts, for example. Nokia said its Network as Code service, which enables applications to programme the network to optimise the performance, could offer L4S technology to drive new business value for mobile operators. 

During the trial at Nokia Arena, two smartphones were used in a congested network to play the same footage, but only one handset used L4S technology. The other phone would halt immediately when attempting to load the streaming content, while the L4S content streamed instantly. The companies worked with streaming firm Kepit Systems and Immersal, a metaverse technology provider for augmented reality (AR) live applications to test different metaverse use cases.
