C-V2X
Cellular Vehicle-to-Everything (C-V2X) is a communication technology that enables vehicles to exchange data with other vehicles, infrastructure, pedestrians, and networks using cellular networks. It supports both direct short-range communication (PC5 interface) and network-based communication (Uu interface) for enhanced safety, traffic efficiency, and autonomous driving applications. C-V2X is standardized by 3GPP and operates in the 5.9 GHz ITS band.
Developers should learn C-V2X when working on connected vehicle systems, smart transportation, or autonomous driving projects, as it provides low-latency, reliable communication for real-time safety applications like collision avoidance and traffic coordination. It is particularly valuable in urban environments and for integrating vehicles with smart city infrastructure, offering advantages over older DSRC technologies with better range and network support.
