What is V2X (Vehicle-to-Everything)?

V2X (Vehicle-to-Everything) is a wireless technology that allows vehicles to communicate with other vehicles and their surroundings.

It incorporates various types of communications like V2V (Vehicle-to-Vehicle) which allows vehicles to communicate with each other and V2I (Vehicle-to-infrastructure) which allows vehicles to communicate with external systems such as buildings, street lights, etc. Other forms of V2X include V2P (Vehicle-to-pedestrian), V2N (Vehicle-to-Network), V2D (vehicle-to-device) and V2G (vehicle-to-grid).

V2X operates using Dedicated Short Range Communication (DSRC) in the 5.9 GHz band. This is a Wi-Fi derivative (802.11p) specifically developed for fast-moving objects that can operate in Non-Line of Sight conditions and harsh weather.

V2X systems share data such as position and speed to the surrounding vehicles and infrastructure, resulting in the reduction of collisions and accidents.

V2X technology also enhances traffic efficiency by providing warnings for upcoming traffic congestion, proposing alternative routes and ensuring eco-friendly driving by reducing CO₂ emissions through adaptive cruise control and smarter transportation management. 

For a V2X vehicle to communicate with another vehicle or roadside object, that object must also use V2X technology. In addition to safety benefits, V2X technology offers a range of everyday convenience advantages. For example, V2X systems integrate automatic payments for tolls, parking, and similar fees. The uses cases of V2X are divided in to 2 parts: Day-1 V2X and Day-2 V2X.

Day-1 V2X use cases cover the foundational use cases of V2X with a focus on safety and traffic efficiency. Whereas Day-2 V2X use cases are the more advanced use cases that come into play once the basics of V2X technology have been taken care of. Click here to learn more about Day-2 V2X use cases.
