A key component for the deployment of wireless communication in critical systems is ultra-high reliability. In scenarios like industrial factory automation and emergency systems, guaranteed error rates below 10⁻⁹ are discussed, which is not feasible with current wireless communication standards. For many future applications, the demand for ultra-reliability wireless communication is expected to increase, since often the installation of wires (which come along with high installation and maintenance cost and downtime due to the wear and tear) is not feasible.
The Fraunhofer Heinrich Hertz Institute develops and evaluates ultra-reliable and robust wireless communication schemes for different applications, from industrial wireless to vehicular communications, thereby addressing 5G in general, and dedicated use cases in specific. A major technique to achieve highly reliable communication is harnessing diversity, especially given the high dynamics of the wireless channels. Novel communication paradigms, such as multi-connectivity, and cognitive components help to provide high reliability even at high mobility. Our software defined radio platform is a central component to verify newly developed schemes under realistic conditions.
