Introduction
Cities can utilize cellular and mobile edge compute technology to implement delivery bots and robotaxis instead of relying on roadside units for network power, as demonstrated by recent research from Verizon and Cisco. A proof-of-concept project in Las Vegas tested this concept.
By leveraging existing cellular networks with a public MEC infrastructure, cities can accelerate the deployment of autonomous vehicles. However, concerns about service limitations have been raised by some government agencies.
A joint test by Cisco and Verizon confirmed that combining Verizon’s LTE network, public 5G Edge with AWS Wavelength, and Cisco Catalyst IR1101 routers meets the latency requirements for autonomous driving applications.
According to Krishna Iyer, director of systems architecture at Verizon, this project showcases the efficacy of mobile edge compute platforms for innovative connected transportation solutions with a more streamlined architecture.
Mark Knellinger, lead transportation solutions architect at Cisco, emphasized the cost-saving benefits for roadway operators by avoiding the significant expenses associated with deploying and managing a dedicated vehicle-to-everything environment.
Components of a vehicle-to-everything infrastructure
Autoweek defines “vehicle-to-everything” as the comprehensive term for a vehicle’s connected communications that assist in navigation and information sharing with the network. This includes real-time traffic data processing, response to changing road conditions, and recognition of road signs and alerts.
Additional communication aspects encompass:
- Vehicle-to-vehicle: Wireless data exchange with other vehicles.
- Vehicle-to-infrastructure: Information sharing with infrastructure components like cameras, streetlights, and signs.
- Vehicle-to-pedestrian: Communication with cyclists and pedestrians for enhanced safety.
- Vehicle-to-network: Data connection and sharing with data centers, road infrastructure, and other vehicles.
Getting multiple stakeholders to agree
An analysis of vehicle-to-infrastructure construction costs highlights the intricate nature of these projects. The report identifies various stakeholders involved in a V2I deployment:
- Road operators
- Mobile network operators
- Suppliers/technology providers
- Vehicle OEMs
- Service provider
- End-users (drivers and fleet operators)
- Academic researchers
Establishing a unified communication architecture is a crucial aspect of these initiatives. The study evaluates the costs of a cellular network-based communication system, encompassing 2G, 3G, 4G, and/or 5G, as well as two direct communication approaches utilizing dedicated spectrum, 802.11p and PC5.
While a mobile communications network-based infrastructure is cost-effective and attractive, concerns persist regarding its ability to support safety-critical services. The report emphasizes that road operators often adopt a risk-averse stance, as direct communication systems are currently the only means to guarantee performance for such services. The limited scope of these services raises doubts about maintaining consistent service levels across the entire road network.
