Welcome to the Chair of Communication Engineering at the University of Siegen
At the Department of Electrical Engineering and Computer Science (Faculty IV), wedevelop and investigate sustainable and energy-efficient solutions for wirelesscommunication and sensor systems. Our research aims to enable environmentally friendly, resource-efficient, and future-oriented technologies for the Internet of Things (IoT) and industrial digitalization.
About Us
Development of Modern Wireless Communication Systems
The Chair of Communication Engineering at the University of Siegen focuses on researchand teaching in sustainable and energy-efficient wireless communication and sensorsystems.
Our work addresses the technological challenges of digital transformation in industry and society, ranging from energy-efficient data transmission to resource-saving integration ofIoT systems.
Our research combines fundamental studies with applied approaches in areas such asbackscatter communication, near-field communication (NFC), wireless power transfer, and RF energy harvesting. The overarching goal is to develop innovative solutions for a sustainable and connected future.
Our Research Profile
