Communication system enabling vehicles to communicate with each other and infrastructure.
Description
Vehicle-to-Everything (V2X) is a communication system encompassing Vehicle-to-Vehicle (V2V), Vehicle-to-Infrastructure (V2I), Vehicle-to-Pedestrian (V2P), and Vehicle-to-Network (V2N) communications.
LTE V2X (C-V2X) uses PC5 sidelink interface for direct communication between vehicles without network involvement, enabling ultra-low latency safety messages. It also supports Uu interface for network-based services.
Purpose & Motivation
V2X was introduced to:
- Enable road safety applications (collision avoidance, emergency braking) - Support autonomous driving with reliable communication - Provide traffic efficiency improvements - Enable new mobility services
