Verizon, Ericsson complete trial of advanced L4S capabilities

Verizon (VZ) and Ericsson (ERIC) recently completed a trial of advanced Low-Latency, Low-Loss, Scalable Throughput (L4S) capabilities that will optimize Verizon’s 5G network for more robust solutions like interactive video, remote control of industrial processes, augmented reality and virtual reality. The L4S trial, conducted in Ericsson’s D-15 5G innovation and co-creation lab in Santa Clara, CA, tested an XR application using an XR virtual reality headset over Ericsson’s 5G stand alone core connecting to Verizon’s C-Band spectrum. The trial demonstrated how enabling L4S signaling in the Radio Access Network allowed content providers to adjust the rates at which they sent their data packets, thereby markedly improving the performance of urgent, high-bandwidth applications over Verizon’s 5G network. The results showed latency reduction by up to fifty percent, demonstrating the potential of L4S as a rate adaptation framework for 5G time-critical high data rate applications.
