Cellular Vehicle-to-Everything, or C-V2X, continues to notch important gains as the preferred technology for vehicles to communicate with one another and with their surroundings. Through its acceptance in standards, string of successful trials, and initial commercialization, C-V2X shows growing promise for greater road safety and mobility, and is important for the assistance of non-line-of-sight sensors for autonomous vehicles.
Here’s a look at the increasing momentum around the standards, maturity, and trials involving this technology.
C-V2X is designed for the most important use cases of connecting vehicles to nearly everything around them:
It facilitates direct communication without relying on network coverage or a cellular subscription. In radio standards that underpin commercial deployment, C-V2X was first defined as part of 3GPP (3rd Generation Partnership Project) Release 14, then Rel-15 and Rel-16 5G NR It builds upon the legacy of safety and mobility standards that had initially used the much older radio as defined in IEEE 802.11p.
The technological maturity of C-V2X has won over automakers (OEMs), including Ford in the U.S. and most vehicle OEMs in China, and the communication is both secure and authenticated. Road operators in those countries have also started to deploy C-V2X roadside units (RSUs). Global regions are aligning their connected-vehicle efforts with the baseline IEEE 1609.2 security services standard.
Within the U.S. Department of Transportation (USDOT), the National Highway Traffic Safety Administration (NHTSA) has emphasized its position of technology neutrality and the Federal Communications Commission (FCC) has proposed 20 MHz for C-V2X in their recent Notice of Proposed Rulemaking, potentially clearing the regulatory path for C-V2X in the U.S. These actions bode well for the 130+ member 5G Automotive Association (5GAA) that includes leading global automakers, telecom companies, and their respective ecosystems.
Thus, all standards are in place and ready.
Extensive laboratory and field tests — followed by initial deployments of C-V2X — have been underway around the world since 2017, bringing greater clarity about how the technology is expected to look and work once deployed. From early activity, the ConVeX trial in Germany announced in January 2017 to the first live demonstration (emergency vehicle) at CES in January 2018, and through the most recent C-SAE C-V2X 4-layer interop test (security) in China in November 2019, Qualcomm Technologies has collaborated with global automotive leaders to extensively test and showcase the advantages and capabilities of C-V2X. Participating automakers that are publicly known have included Audi, BMW, FCA, Ford, Nissan, PSA, SEAT, and many more indirectly or privately supported, including numerous Chinese domestic and joint-venture automakers.
The Crash Avoidance Metrics Partners LLC (CAMP) has sponsored the goal of providing a rigorous and objective evaluation of the technology — having been setup two decades ago to evaluate V2X using IEEE 802.11p. The evaluation included how the technology performs in the field and at scale, where channel congestion issues can be problematic to any radio technology. CAMP, originally formed by Ford Motor Company and General Motors, provides a framework for crash-avoidance research aimed at improving auto safety. For C-V2X, CAMP developed test procedures, conducted testing, assessed performance, and is documenting the results, which have already been released to SAE International to support and inform V2V standardization. In addition to Ford and GM, Hyundai, Nissan, and Qualcomm Technologies were involved with CAMP’s C-V2X testing.
With encouraging results from ongoing trials, C-V2X has been tested and is ready for commercial deployment through a community of suppliers at each stage of the global C-V2X ecosystem:
While many regions are in various stages C-V2X deployment, China is an example of a mature C-V2X ecosystem built on the Qualcomm Technologies chipsets with a value chain of module vendors, RSU vendors, Tier 1 suppliers, and OEMs. Since 2018, the technology has also enjoyed strong support among Chinese vehicle manufactures, road operators, and regulators.
