New generation of vehicles need to deliver different types of applications in various domains like infotainment, telematics, driver assistance and autonomous driving with maximum reliability, safety and privacy.
As a result, vehicles should be able to communicate not only with other vehicles, but also with pedestrians, roadside equipment and the internet. Automobiles are taking a more pro-active role by warning drivers of potential collisions with oncoming vehicles, monitoring intersections, gathering real-time traffic information pieces, exchanging incident alerts and emergencies with quick response and paramedic services.
The requirements for each domain and the associated use cases can be very different and have an important impact on the telecommunication standards used to provide the adequate services. This paper aims at providing an overview of the main standards and why features brought by 5G standard will be key to address the different V2X requirements in the coming years.
