Verizon, Cisco LTE demo, MEC for C-V2X millisecond communications

Cisco Transportation Solutions Architect: “In any vehicle, seconds count for passenger and pedestrian safety. In connected vehicles, milliseconds matter more’

Cisco and Verizon traveled to Las Vegas to demonstrate how cellular and mobile edge computing (MEC) technology can enable low-latency autonomous driving solutions without using physical road units (Rus). For cities, like Vegas, that have already implemented public MEC technologies, this strategy represents a “simpler and more efficient path” to enabling autonomous vehicle applications, the companies said.

In a blog post, Cisco Transportation Solutions Architect Mark Knellinger explained the importance of fast communication when it comes to autonomous driving: “In any vehicle, seconds count for the safety of passengers and pedestrians. In connected vehicles, milliseconds matter more,” he said.

Currently, this low-latency communication between vehicles and surrounding connected infrastructure is achieved using roadside radio units, which extend radio signals, thereby reducing communication time. However, these radio units are expensive and time-consuming to deploy.

But now Cisco and Verizon say they’ve “proven” they can replace those units with a combination of the carrier’s LTE network, public 5G Edge with AWS Wavelength, and the vendor’s Catalyst IR1101 routers while still meeting latency thresholds required for autonomous driving applications. .

In fact, by using LTE and edge computing to virtualize the role of roadside units, C-V2X (cellular vehicle-to-everything) communications have proven to be more streamlined, which Verizon and Cisco believe will likely lead to improved efficiency and profitability. for municipalities, infrastructure providers and application developers working with autonomous vehicles.

“This test is an important step in proving that the future of connectivity for IoT applications can be powered by cellular,” said Krishna Iyer, director of systems architecture at Verizon. “We are marking the strength of mobile edge computing platforms for connected transportation innovation with a much more streamlined architecture. With Cisco technologies, we are laying the foundation for realizing ubiquitous IoT in the connected and autonomous future of driving. »
