Industrial Radio Laboratory (IRL) Dresden and Rohde & Schwarz collaborate on Industry 4.0 wireless technologies

Rohde & Schwarz supplies IRL Dresden with high-performance network scanners to explore reliable and resilient wireless technologies for industrial applications. This test equipment is used for distributed real-time radio spectrum and interference monitoring.

To enable Industry 4.0 use cases, such as mobile robots or autonomous vehicles, industrial network deployments must guarantee very high availability, reliability, and many low-latency communication cases. The latest release of 3GPP R1 enhancements enables 5G NR to support Ultra-Reliable Low Latency Communications (URLLC), ideal for private campus network deployments. However, as with any wireless system, the frequency bands in use for wireless communication links are subject to potential interference.

IRL Dresden is dedicated to the research and testing of radio systems for industrial applications. To this end, IRL Dresden and Rohde & Schwarz collaborated. Rohde & Schwarz is a leading provider of 5G NR test solutions including portable and easy-to-use test equipment to evaluate network performance in the field. Rohde & Schwarz supplied IRL Dresden with high-performance network scanners for distributed real-time radio spectrum and interference monitoring. With the app, the researchers collected important data on how to detect, locate and prevent interference, providing an interference-free frequency band for reliable wireless connections.

IRL Dresden is one of four regional laboratories of the German Industrial Radio Laboratory (IRLG) dedicated to the research and development of current and future industrial wireless technologies. IRLG enables innovation, supports businesses and collaborates with stakeholders in the political and business worlds. IRL Dresden has a particular focus on detecting, locating and reducing radio interference and improving network resilience through real-time measurements of time-varying channels and coordinated spectrum sensing.

Dr. Norman Franchi, project leader at IRL Dresden, said: “The ability to deal with predictable and unpredictable disturbances and provide appropriate self-optimizing and self-healing mechanisms is still insufficient. Automated and reliable automated methods to detect, locate and avoid unintentional self-interference as well as man-made interference such as jammers are becoming increasingly important and challenging. This is especially true in dynamic industrial applications and communication scenarios. Our collaborative The goal is to analyze and evaluate the requirements for measuring sensors and networks and derive real-time performance that can be achieved.”

Anne Stephan, VP Mobile Network Testing at Rohde & Schwarz, said: “Industrial park network deployments, whether based on private spectrum or network slicing provided by public operators, typically establish a rigorous use case. In collaboration with leading research institutes like Dresden, we can not only support basic research, but also gain first-hand information that can be used to adapt our leading mobile network testing solutions for Industry 4.0.”
