Verizon (NYSE: VZ) and Ericsson (NASDAQ: ERIC) have recently completed a trial of advanced Low-Latency, Low-Loss, Scalable Throughput (L4S) that showed how Verizon’s 5G network can be optimized for interactive video, remote control of industrial processes, augmented reality and virtual reality. The results of the trial showed latency reduction of up to 50 percent, demonstrating the potential of L4S as a rate adaptation framework for 5G time-critical high data rate applications.
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. L4S signaling in the RAN allowed content providers to adjust the rates at which they sent their data packets, thereby improving the performance of urgent, high-bandwidth applications over Verizon’s 5G network.
The L4S capability enables content providers to use the specific network resources for a variety of time-critical applications, including entertainment, gaming, AR/VR, real-time video conferencing, Vehicle to Everything (V2X) communications, tele-operated driving, and drone operations. The introduction of L4S capability in Verizon’s 5G network is the latest technology advancement by the carrier in the past several months, as 5G technology advances and matures, according to Verizon.
