Verizon uses 5G network slicing for enhanced video calling following public-safety trials

Verizon is introducing its first consumer-facing feature based on 5G network slicing, a technology that optimizes performance for specific uses by allocating dedicated network resources, reports the Verge. Its new Enhanced Video Calling service promises improved video and audio quality, prioritizing its quality over less critical traffic during network congestion.

Network slicing is a 5G technology that allows operators to virtually segment their network and then optimize each segment for specific uses, such as dedicating network resources to first responders during emergencies, improving quality of service during telemedicine, and supporting automation via internet of things. Slicing requires a 5G SA (stand alone) network, whereas many US carriers have rolled out 5G air interfaces connected to 4G cores. While T-Mobile has operated a 5G SA network since at least 2022, the Enhanced Video Calling rollout indicates Verizon has effectively reached parity.

This launch follows a series of trials by Verizon, including public safety demonstrations using network slicing to prioritize video data for first responders. Earlier this year, Verizon tested the technology in Phoenix, Arizona, utilizing Axon 3 video cameras to support mission-critical operations. Verizon's enhanced video calling is available only to users on Verizon’s $90 per month Unlimited Ultimate plan and requires compatible devices, such as the iPhone 14 or newer models.

Meanwhile, the carrier continues to fight off the Salt Typhoon attack, which T-Mobile among few others appears to have mitigated early.
