Centre for Networked Intelligence

Dear All, Networks Seminar, supported by the Centre for Networked Intelligence, is a technical discussion forum in topics including but not limited to computer networks, machine learning, signal processing, and information theory. The seminar series has a webpage hosted at https://cni.iisc.ac.in/seminars/. You are invited to the following seminar held as part of this series. Title: Wireless Powered Communications in the Era of 6G Speaker: Prof. Ioannis Krikidis, Professor, University of Cyprus Time: 12:30 PM - 1:30 PM (IST) Date: 28 September 2026 Venue: Online on Zoom Zoom link: https://us06web.zoom.us/j/83388976389?pwd=XcpO3GhLxsR14a7SVbPx33HQQa1jbt.1 Zoom Meeting ID: 833 8897 6389, Pass Code: NSSIISc Webpage Link: https://cni.iisc.ac.in/seminars/2026-09-28/ <https://cni.iisc.ac.in/seminars/2026-09-28/> Abstract: Conventional energy-constrained wireless systems such as sensor networks are powered by batteries and have a limited lifetime. Wireless power transfer (WPT) is a promising technology for energy-sustainable networks, where terminals can harvest energy from dedicated electromagnetic radiation through appropriate electronic circuits. The integration of WPT technology into communication networks introduces a fundamental co-existence of information and energy flows; radio-frequency signals are used in order to convey information and/or energy. The efficient management of these two flows through sophisticated networking protocols, signal processing/communication techniques, and network architectures, gives rise to a new communication paradigm called wireless-powered communications (WPC). In this talk, we discuss the principles of WPC and we highlight its main network architectures as well as the fundamental trade-off between information and energy transfer. By following a bottom-up cross-layer approach, several examples, that deal with the fundamentals of WPC as well as its integration in modern communication systems, are presented. Specifically, we deal with circuit models for WPT, information-theoretic limits, signal processing aspects, and waveform design, system-level analysis by using stochastic geometry tools. Future research directions and challenges are also pointed out. Bio: Ioannis Krikidis (F’19) received a diploma in Computer Engineering from the Computer Engineering and Informatics Department (CEID) of the University of Patras, Greece, in 2000, and the M.Sc and Ph.D. degrees from Ecole Nationale Superieure des Telecommunications (ENST), Paris, France, in 2001 and 2005, respectively, all in electrical engineering. He is currently a Professor at the Department of Electrical and Computer Engineering, University of Cyprus, Nicosia, Cyprus. His current research interests include wireless communications, 6G communication systems, wireless-powered communications, fluid-antenna systems, quantum information processing. ALL ARE WELCOME.
