C-V2X (Cellular Vehicle-to-Everything) is an advanced wireless communication technology currently used in ITS (Intelligent Transportation Systems) for autonomous driving; this technology extends the coverage of autonomous driving and improves blind spot detection capabilities.
I. C-V2X Technology Characteristics: Compared to commonly used traditional sensors, C-V2X is more cost-effective and more suitable for large-scale deployment. Based on the PC5 interface, C-V2X uses Sidelink technology (direct vehicle-to-vehicle communication) to achieve low-latency UrLLC (critical mission) sensor connectivity, with a communication range exceeding that of conventional wireless networks.
II.C-V2X and Autonomous Driving: In 2020, 5G (NR) technology was fully commercialized globally; mobile communication operators and relevant departments are eagerly anticipating its greater role in people's daily lives due to its low latency, high reliability, and high throughput. Level 3 (conditional automation) or Level 4 (highly automated) autonomous driving is a typical example of 5G (NR) applications, where the URLLC (ultra-reliable low-latency communication) used perfectly showcases the capabilities of mobile technology. The evolution of C-V2X and the deployment of 5G (NR) complement each other, jointly building a new ecosystem that will change the way people drive and manage traffic in the future.
III.C-V2X Applications: Given that approximately 1 million people die in road traffic accidents worldwide every year, making traffic accidents the eighth leading cause of death globally, C-V2X (Cellular Vehicle-to-Everything) is becoming a popular solution to this problem. As a complete communication system, it specifically includes four categories of applications:
