What is its in V2X?

The key components of V2X technology include V2V (vehicle-to-vehicle) and V2I (vehicle-to-infrastructure) . V2V allows vehicles to communicate with other vehicles on the road, while V2I allows vehicles to communicate with external entities, such as traffic lights, parking spaces, cyclists, and pedestrians.

An On-Board Unit is a DSRCS transceiver that is normally mounted in or on a vehicle, or which in some instances may be a portable unit . An OBU can be operational while a vehicle or person is either mobile or stationary. The OBUs receive and contend for time to transmit on one or more radio frequency (RF) channels.

Cellular Vehicle-to-Everything (C-V2X) is a unified connectivity platform designed to offer vehicles low-latency vehicle-to-vehicle (V2V), vehicle-to-roadside infrastructure (V2I) and vehicle-to-pedestrian (V2P) communication.

RSU generally has multiple network interfaces to connect to the vehicles, other RSUs, and ISPs (Internet Service Providess).
