Telstra to upgrade 5G network with Ericsson's L4S

Telstra has completed Australian-first trials of Ericsson’s new Low Latency Low Loss Scalable (L4S) time-critical communications technology on its commercial network.

The trial of the 5G networking technology was completed at Telstra’s 5G Innovation Centre on the Gold Coast.

L4S is a software solution for adapting transmission bitrates in real time for time-critical communication on a 5G network, to compensate for network congestion delays.

Telstra plans to implement the technology across its 5G network to improve the user experience while using the network for use cases including cloud gaming over 5G.

Telstra Executive for Technology Development and Solutions Channa Seneviratne said the planned upgrade forms part of Telstra’s efforts to continually improve its 5G network.

“We have been working with Ericsson as a technology partner to constantly improve the customer experience via enhanced network capabilities,” he said.

“Time-Critical Communication tools such as L4S will allow us to deliver consistent low latency, which is crucial for applications like real-time video, AR/VR and cloud gaming.”

L4S can be deployed as a software product for both public and private 5G networks using any 5G frequency band.

“This Australian first achievement with Telstra is the missing piece for 5G to deliver on the promise of consistent low latency, high reliability and superior end-user experience,” Ericsson Australia and New Zealand Head Emilio Romeo said.

“Unlocking diverse latency-sensitive applications will be revolutionary for industries and enterprises such as the Australian gaming industry and beyond.”
