•••3••• Innovationen Reality check 5G test bed for automotive applications On May 5, 2022, the Fraunhofer Institute for Integrated Circuits IIS officially opened its 5G Bavaria automotive test bed. In a five-kilometer test area located on the southern edge of the Bavarian city of Rosenheim, automotive companies now have the opportunity to put 5G functions for connected driving through their paces in a realistic environment. Before new appl icat ions are launched on the market, they are put through an exhaustive battery of tests, some under real conditions. Now, the 5G Bavaria automotive test bed offers companies a realistic environment in which to test 5G mobile communications appl ications designed for connected dr iving. Located on the southern outskirts of Rosenheim, the facility features a five-kilometer test area, covered by a closed 5G network supported by multiple base stations. The controlled, reproducible test area features a varied road network, which includes urban areas with bridges and underpasses as well as sections of the B15 and A8 highways. Tests focus on exchanging data in real time “The automotive test bed is designed specially for developers and users that want to test new connectivity solutions in a real road network,” says Martin Speitel, Group Manager Automotive at Fraunhofer IIS. “The focus is on testing transmission technology and evaluating specif ic transmitter and receiver components.” Determining essent ial per formance parameters such as latency, reliability and throughput provides valuable insights into a given application’s quality of service and user experience. In addition to the air interface, prototype transmitter and receiver components can also be tested under real conditions. Potential measurement scenar ios include determining the inf luence that (massive) MIMO technologies have on reception quality, data throughput and possible driving speeds. There is also the option of using the C-V2XSim platform to simulate certain test scenar ios before testing them on the road. From research to application The automotive test bed is part of the 5G Bavar ia ini t iat ive, which is funded by the Bavarian Ministry of Economic Affairs, Regional Development and Energy. The initiative’s goal is to transfer research related to the new 5G mobile communications standard into application. This paves the way for exploring the feasibility and limitations of 5G technology early on under real conditions and accelerating the product development process.
