Cellular V2X trials to start in California
The tests are intended to demonstrate how C-V2X technology can improve vehicle safety, make automated driving easier and increase traffic efficiency. The tests will also demonstrate to car manufacturers and road operators the benefits of mobile radio technology in vehicles as well as synergies between the use of mobile radio base stations and roadside infrastructure. The first test phase is scheduled to start this year. Participating companies include AT&T, Ford, Nokia and Qualcomm as well as engineering services provider McCain.
C-V2X was defined in 2017 as an extension of the global mobile communications standards as part of the 3rd Generation Partnership Project (3GPP). The standard is in some way in competition with the DSCR, which was originally designed as a standard technology for V2X applications and is based on a modified version of the 802.11 WiFi standard. C-V2X opens up further application options for automated communication among vehicles and between vehicles and the roadside infrastructure.
The direct communication mode provided in the C-V2X standard is designed to help extend the role of wireless technology in road safety applications by facilitating the ability of vehicles to communicate directly with other vehicles, pedestrians and road infrastructures such as traffic signs and construction zones over the 5.9 GHz band using the 5.9 GHz band without the involvement of a cellular network, or cellular network subscription. Complementary to other Advanced Driver Assistance Systems (ADAS) sensors, such as cameras, radar, and LIDAR, C-V2X technology is designed to support 360-degree non-line-of-sight (NLOS) awareness, and is designed to extend a vehicle’s ability to see, hear, and understand the environment down the road, at blind intersections, or in bad weather conditions.
For this trial, C-V2X platforms will be installed in Ford vehicles using the Qualcomm 9150 C-V2X solution to facilitate direct communications, and are complemented by AT&T’s 4G LTE network communications and ITS platform that takes advantage of wireless base stations and multi-access edge computing technology from Nokia. For the communication technologies being deployed, McCain will help facilitate the integration with existing and emerging traffic signal control infrastructure.
Testing will support direct C-V2X communications operating in the 5.9 GHz ITS spectrum to explore the safety enhancements of V2V use cases, including do not pass warning, intersection movement assist, and left turn assist. The trials will also support advanced vehicle communication capabilities for improved traffic efficiencies, such as real-time mapping updates and event notifications relayed using AT&T’s cellular network and Nokia Cloud Infrastructure.
