The 5G Automotive Association (5GAA), Audi, Ford and Qualcomm Technologies have announced what they claim is the world’s first demonstration for Cellular Vehicle-to-Everything (C-V2X) direct communications technology interoperating across vehicles from different manufacturers.
C-V2X is a global solution based on 3GPP specifications for V2X communications to support improved automotive safety, automated driving, and traffic efficiency, with ongoing evolution designed to offer forward compatibility with 5G, and leveraging upper layer protocols defined by the automotive industry, including Society of Automotive Engineering (SAE) and ETSI organizations.
The demonstration showcased the benefits of using C-V2X on the globally harmonized 5.9-GHz ITS spectrum band for vehicle-to-vehicle (V2V) collision avoidance and improved road safety without any dependency on cellular operator network involvement, credentials or coverage.
The organizations also unveiled initial field test results showing a significant range, reliability and performance advantage of C-V2X direct communications, with more than twice the range and improved reliability compared to 802.11p radio technology.
The demo exhibited various road safety scenarios, such as situations with obstructed or no visibility, including Left Turn Assist and Emergency Electronic Brake Light use cases, in which V2V communications alerted surrounding vehicles when cars were turning left or braking. A vulnerable road user (VRU) demo showcased what can be possible with future vehicle-to-pedestrian (V2P) communications.
Use cases for vehicle-to-infrastructure (V2I) communication were also demonstrated, which showed how direct communications can work closely with traffic signal controllers to ensure reduction in carbon emissions and optimization of traffic efficiency in cluttered intersections and dense environments.
C-V2X solutions are expected to be more cost efficient and economical over competing technologies as this functionality gets integrated into the base cellular modem product that automakers equip in every vehicle.
5GAA chairman Christoph Voigt said that after years of development by carmakers, technology providers and the automotive ecosystem at large, “C-V2X is ready to improve road safety with deployment in production vehicles and road infrastructure as soon as 2020.”
Voigt also said the C-V2X demo “represents a key step towards the next generation of cellular technology, 5G.”
5GAA, Audi, Ford and Qualcomm plan to showcase another live C-V2X interoperability demonstration at the upcoming Intelligent Transportation Society of America (ITS-A) World Meeting in Detroit from June 4-7.
