讲座人 Prof. Riku Jäntti
讲座人介绍 Riku Jäntti is an Associate Professor (tenured) in Communications Engineering and the head of the Department of Communications and Networking at Aalto University School of Electrical Engineering, Finland. He received his M.Sc (with distinction) in Electrical Engineering in 1997 and D.Sc (with distinction) in Automation and Systems Technology in 2001, both from Helsinki University of Technology (TKK). Prior to joining Aalto (formerly known as TKK) in August 2006, he was professor pro tem at the Department of Computer Science, University of Vaasa. Prof. Jäntti is a senior member of IEEE and associate editor of IEEE Transactions on Vehicular Technology. He is also IEEE VTS Distinguished Lecturer (Class 2016). The research interests of Prof. Jäntti include radio resource control and optimization for machine type communications, Cloud-based Radio Access Networks, spectrum and co-existence management, and quantum communications. 
讲座内容 Low-power wireless communication has been identified as one of the key enabling technologies for the Internet of Things (IoT). The performance of the contemporary IoT connectivity solutions is mainly limited by congestion, interference, and limited operation time with the battery. These limitations hamper the scaling of the IoT deployments. In this talk, we envision a new solution to the IoT connectivity combining existing and emerging wireless communication systems (hereafter legacy systems) with a new layer of ultra-low-power or passive ambient backscatter communication (AmBC). It can operate under very low signal-to-noise ratio conditions, share the spectrum with legacy systems without causing harmful interference to them, and scale to support a large number of devices. We will also discuss how the emerging microwave quantum technology can be utilized to enhance the performance of backscatter communications beyond the limits of classical solutions.
