Connected Vehicles – Cellular V2X

2 days

This course gives you a broad understanding in how vehicles communicate between each other, with infrastructure in the vicinity or with a traffic control or surveillance system. There are three main standards today which are all presented during the course. Emphasis is however on the standard referred to as cellular V2X which uses 4G and 5G radio technology and the direct communication channel referred to as side-link. By connecting vehicles, road accidents are drastically reduced. The technology can also be used in factories and mines where the environment may be hostile or too dangerous for human drivers. The French train operator SNCF is also considering using the technology for controlling trains. Connected vehicles are a small but important part in the digitalisation of our society and can, together with electrification of our vehicles, create a more sustainable society with fewer accidents.

Course Objectives

The course will give you a survey over the technologies available for connected vehicles and an understanding of the actors driving the market. After concluded training, you will have a general understanding for the available technologies with a deepened knowledge in the technology using 4G and, to some extent 5G. The technology for the side link in 5G is presented with what is known as the standardisation process is on-going (ready late Q1 2020).

Course Contents

• Actors on the market, standards, legislation
• Drivers for connected vehicles, business cases, the fully digitalised traffic system
• DSRC, the technology based on Wi-Fi standard IEEE 802.11p is studied and we examine architecture, messages between vehicles, messages between vehicles and infrastructure and some use cases.
• ETSI C-ITS, the European standard for an intelligent transportation system is studied and we study the architecture, messages and some use cases.
• 3GPP, the organisation that standardises mobile systems (4G and 5G), has adapted the systems to vehicle-to-vehicle communication and vehicle-to-infrastructure communication. The architecture is studied as well as advanced use cases for 4G and 5G. Functions that will enhance the connected vehicle area are also studied such as enhanced multimedia broadcast (eMBMS), edge computing and network slicing. Finally, the function for side link in 5G is studied with some new and interesting features.
• Positioning, the technology for satellite navigation is studied.
• Security is studied from different angles.
