Wireless Communication for Automotive

Engineers and scientists are looking for processes and technologies to enhance traffic flow through sophisticated traffic management. The established intelligent transportation system (ITS) ITS-G5 is expected to avoid traffic congestion and increase overall traffic efficiency.

End-to-end digitization from single vehicles to road infrastructure and backend servers provides the basis for continuous traffic flow control and management. Technological progress in the automotive industry towards automated driving and development of advanced driver assistance systems (ADAS) is propelling the fully digital transportation system.

The Cooperative ITS (C-ITS) transportation system enables all road users including pedestrians to communicate and cooperate with each other as well as promises to increase efficiency and reduce road traffic fatalities and serious injuries. Reducing road traffic accidents is the primary goal of government agencies around the globe.

A mobile communications system is required that supports the reliable exchange of road traffic data even in scenarios where road users are traveling at high speed.

This white paper describes the technical aspects of wireless communications with a focus on the automotive application segment. The objective is to outline the differences between the two communications paths, i.e., the network-oriented path and direct mode communications.
