5G Bavaria Automotive Test Bed

Connected driving

The 5G Bavaria automotive test bed provides the infrastructure for testing the latest 5G functionalities in real traffic environments. With the properties it offers, the 5G mobile communications standard is the ideal basis for connecting vehicles and traffic infrastructure, where flexible and fast, real-time capable data transmission is key. Thus, 5G paves the way for optimized traffic concepts that enable vehicles to communicate independently with their environment, recognize dangerous situations and be intelligently integrated into the traffic flow.

Testing connected automotive applications with 5G

The automotive test bed will permit testing of various mobility applications in realistic conditions using the latest 5G mobile technology:

Connected car scenarios

When cars are connected to the Internet, they can be equipped with a whole host of additional functions. Measuring packet loss rates and other performance characteristics directly in the context of the application provides a way to test service quality and user experience.

Automated driving

Evaluating the quality of data connections between the vehicle and the network and between vehicles themselves in real road traffic conditions is a key aspect of developing use cases for automated driving. The quality indicators recorded in the automotive test bed can be used in the development of applications for remote driving or platooning (connecting trucks in a convoy).

Machine learning approaches

Exploring machine learning approaches for predicting and improving reception quality makes it possible to improve the security and reliability of vehicle communication and positioning, e.g. for early accident detection.

High-throughput scenarios

Testing the use of special transmission methods for temporary, high data throughput provides insight into how such “data showers” can be used for vehicle updates or other applications.

Other mobility scenarios: remote drones (example)

Remote drones can be deployed for monitoring and optimizing traffic. Testing in this field is required to determine the extent to which the mobile communications infrastructure can be improved to enable drones to fly beyond-line-of-sight (BLOS) under the safest conditions.

Testing opportunities accelerate product development

The test bed is available for companies, research institutions and universities to use, with Fraunhofer IIS providing consulting and testing services based on its expertise in communications technology and 5G.

With the 5G Bavaria automotive test bed, stakeholders can develop and test new applications or next-generation mobile technology components and prepare them for large-scale production in a controlled, reproducible and confidential environment. It can be used both for testing transmission technology and for evaluating specific transmitter and receiver components:

Transmission technology

The focus here is on the air interface of the 5G standard and the telecommunications aspects of vehicle communication. This includes validation and improvement of channel models and the determination of specific performance indicators such as latency, reliability and throughput.

Transmitter and receiver components in the vehicle

Even as prototypes, transmitter and receiver components can be tested under real conditions. Of interest here are investigations into the optimum positioning of antennas (installation location, number and geometry) in relation to the frequencies used. It is also possible to determine the influence that (massive) MIMO technologies have on reception quality, data throughput and potential driving speeds.

Features of the 5G Bavaria automotive test bed


The 5G Bavaria automotive test bed is currently being set up along an existing network of roads in and around the Bavarian town of Rosenheim.
