According to World Health Organization figures, road traffic injuries are the leading cause of death among young people aged 15–29 years. More than 1.2 million people die each year worldwide as a result of traffic crashes. Vehicle-to-Everything (V2X) technologies, starting with 802.11p and evolving to Cellular V2X (C-V2X), can help bring safer roads, more efficient travel, reduced air pollution, and better driving experiences.
V2X will serve as the foundation for the safe, connected vehicle of the future, giving vehicles the ability to "talk" to each other, pedestrians, roadway infrastructure, and the cloud. It’s no wonder that the MIT Technology Review put V2X on its 2015 10 Breakthrough Technologies list, stating: “Car-to-car communication should also have a bigger impact than the advanced vehicle automation technologies that have been more widely heralded.”
V2X is a key technology for enabling fully autonomous transportation infrastructure. While advancements in radar, LiDAR (Light Detection and Ranging), and camera systems are encouraging and bring autonomous driving one step closer to reality, it should be known that these sensors are limited by their line of sight. V2X complements the capabilities of these sensors by providing 360 degree non-line-of sight awareness, extending a vehicle’s ability to “see” further down the road – even at blind intersections or in bad weather conditions.
So, how long do we have to wait for V2X to become a reality? Actually, V2X technology is here today. Wi-Fi-based 820.11p has established the foundation for latency-critical V2X communications. To improve road safety for future light vehicles in the United States, the National Highway Safety Administration is expected to begin rulemaking for Dedicated Short Range Communications (DSRC) this year.
Beyond that, tomorrow’s autonomous vehicles require continued technology evolution to accommodate ever-expanding safety requirements and use cases. The path to 5G will deliver this evolution starting with the C-V2X part of 3GPP release 14 specifications, which is expected to be completed by the end of this year.

C-V2X will define two new transmission modes that work together to enable a broad range of automotive use cases:
To accelerate technology evolution, Qualcomm is actively driving the C-V2X work in 3GPP, building on our leadership in LTE Direct and LTE Broadcast to pioneer C-V2X technologies.
The difference between a vehicle collision and a near miss comes down to milliseconds. With approximately twice the range of DSRC, C-V2X can provide the critical seconds of reaction time needed to avoid an accident. Beyond safety, C-V2X also enables a broad range of use cases – from better situational awareness, to enhanced traffic management, and connected cloud services.
C-V2X will provide a unified connectivity platform for safer “vehicles of tomorrow.” Building upon C-V2X, 5G will bring even more possibilities for the connected vehicle. The extreme throughput, low latency, and enhanced reliability of 5G will allow vehicles to share rich, real-time data, supporting fully autonomous driving experiences, for example:
Beyond pioneering C-V2X and helping define the path to 5G, we are delivering new levels of on-device intelligence and integration in the connected vehicle of tomorrow. Our innovations in cognitive technologies, such as always-on sensing, computer vision, and machine learning, will help make our vision of safer, more autonomous vehicles a reality.
