Vehicle-to-everything (V2X) communication is the passing of information from a vehicle to other entities, such as V2I (vehicle-to-infrastructure), V2N (vehicle-to-network), V2V (vehicle-to-vehicle), V2P (vehicle-to-pedestrian), V2D (vehicle-to-device) and V2G (vehicle-to-grid). There are two main types of V2X communication technology: WLAN-based and cellular-based. WLAN-based V2X (IEEE 802.11p) supports direct communication between vehicles (V2V) and between vehicles and infrastructure (V2I). This technology, referred to as Dedicated Short-Range Communication (DSRC), uses the underlying radio communication provided by 802.11p. V2X based on LTE as the underlying technology is generally referred to as "cellular V2X" (C-V2X) to differentiate itself from the 802.11p-based V2X technology. In addition to the direct communication (V2V, V2I), C-V2X also supports wide area communication over a cellular network (V2N).
