Interoperability of C-V2X signals between Ford and Audi demonstrated

Technology News |
5G Automotive Association (5GAA) and carmakers Audi and Ford Motor Company as well as Qualcomm Technologies have demonstrated the interoperability of Cellular Vehicle-to-Everything (C-V2X) direct communications across vehicles from different manufacturers.

C-V2X is positioned as a global solution for V2X communications to support improved automotive safety, automated driving and traffic efficiency. As such, it is a contender to the well-entrenched DSRC technology based on the IEEE 802.11p standard. Currently, Qualcomm-backed C-V2X seems to have a winning streak – it has been recognized by the 3rd Generation Partnership Project (3GPP) as the only V2X technology based on globally specifications 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 the European Telecommunications Standards Institute (ETSI) organizations.

The demonstration showcased the benefits of using C-V2X real-time direct communications on the globally harmonized 5.9 GHz ITS spectrum 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.

Featuring Audi and Ford vehicles which incorporate the C-V2X technology utilizing the C-V2X chipset from Qualcomm Technologies, the showcase exhibited various scenarios of how C-V2X communications can be beneficial for road safety. These scenarios included situations with obstructed or no visibility, including Left Turn Assist and Emergency Electronic Brake Light use cases, in which vehicle-to-vehicle (V2V) communications alerted surrounding vehicles when cars were turning left or braking. 

Additional use cases were featured, including a vulnerable road user (VRU) demonstration showcasing what can be possible with future vehicle-to-pedestrian (V2P) communications. Use cases for vehicle-to-infrastructure (V2I) communication were also demonstrated, which showcased 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.

Designed with a focus on security, C-V2X benefits from established security transport layers and application protocols defined by the automotive standards communities, including SAE, ETSI, International Standards Organization (ISO), and Institute of Electrical and Electronics Engineers (IEEE) 1609, and Qualcomm’s decades of investment in cellular technologies. 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.
