The digitalization moves forward rapidly in society and industry. Thereby, the access to ubiquitous connectivity becomes more important than ever in our private and business environments. Along with the development of 5G mobile communications as well as real-time local wireless networks, a multitude of new industrial applications will be enabled by meeting requirements, which have been feasible only through cable-based solutions in the past. The ever growing data rate, the decreasing end-to-end latency to meet real-time requirements, and the enhancement of network reliability are current aims in research and development in wireless network optimization.
