V2X Communication, or Vehicle-to-Everything communication, is a technology that enables vehicles to communicate with each other and with infrastructure, pedestrians, networks, and other entities to improve road safety, traffic efficiency, and energy savings. It encompasses various communication types like V2V (Vehicle-to-Vehicle), V2I (Vehicle-to-Infrastructure), V2P (Vehicle-to-Pedestrian), and V2N (Vehicle-to-Network), each playing a critical role in the ecosystem of connected and autonomous vehicles.
