6G technology as a foundation for future preventive healthcare

The upcoming 6G mobile communication standard offers significant potential to accelerate digital transformation in healthcare. In particular, the aggregation of data from wearable sensors could enhance the efficiency of preventive healthcare strategies.  

To explore this potential, researchers at University of Kaiserslautern-Landau and the German Research Center for Artificial Intelligence are designing a functional demonstrator. This system integrates medical sensors through mobile networks and a unified communication protocol to make biomedical data accessible across platforms. 

The research focuses on enabling a comprehensive and individualized health profile for patients. The team uses common sensors from fitness trackers and connects them across manufacturers. Compatibility is a major challenge: most market-available sensors operate within closed systems, leading to fragmented data storage. These isolated data silos limit their usefulness in preventive care. 

Jan Herbst, part of the research team, explains: “With rapid advancements, especially in human-machine communication, the 6G technology opens up numerous groundbreaking applications in medicine,” he says. “Focusing on effective preventive healthcare, we aim to enable doctors to monitor their patients’ health more efficiently and detect critical conditions and risks at an early stage.” 

To overcome compatibility issues, the researchers use specially designed printed circuit boards (PCBs) as carriers for the sensors and work with manufacturers providing interoperable components. A new network protocol, developed as part of the project, enables data exchange and aggregation across the system. 

The chosen network topology follows a ring layout: “In this setup, the sensors are connected in a closed loop, ensuring efficient and reliable data transmission. Each sensor communicates directly with its neighbor, resulting in low latency and high fault tolerance,” says Herbst. This approach lays the groundwork for continuous patient monitoring and supports the development of a resilient and digitally integrated healthcare system. 

The demonstrator is part of the Open6GHub and 6G Health projects. Open6GHub is coordinated by Professor Hans Dieter Schotten, Chair of Wireless Communication and Navigation at RPTU and Head of the Intelligent Networks Department at DFKI. Alongside RPTU and DFKI, several other universities and research institutions are involved. 

Their goals include developing a comprehensive 6G architecture and implementing end-to-end solutions across various domains: 

• extended network topologies with highly agile so-called organic networking 

• security and resilience 

• THz and photonic transmission methods 

• sensor functionalities in the networks and their intelligent use and further processing 

• application-specific radio protocols
