讲座题目：Wireless Communications Spectrum and Radiation
Kun Yang (杨鲲) obtained his PhD from the Department of Electronic & Electrical Engineering of University College London , UK, and his MSc and BSc degrees were both from Jilin University. He is currently a Chair Professor and the Head of Network Convergence Laboratory in the School of Computer Science and Electronic Engineering, University of Essex, UK. Before joining in the University of Essex at 2003, he worked at UCL on several EU research projects such as FAIN, MANTRIP, CONTEXT in the area of IP network management, active networks and context-aware services. Now his main research interests focus on heterogeneous wireless networks, future Internet architecture and its enabling technologies such as network virtualization, software defined networking, information centric networking, etc. He has published more than 80 journal papers and books, in addition to 80+ major conference papers. He manages research projects funded by EU FP7/H2020, EPSRC, and industries such as British Telecom. He serves on the editorial boards of both IEEE and non-IEEE journals.
Mobile communications need wireless spectrum. According to the Information Theory, the higher the frequency is the higher the transmission data rate is. While people enjoy the high speed of modern mobile communication, they also worry about the negative impact high frequency radiations make on human body. Starting with a brief introduction of mobile communication and its frequency use particularly in 5G mobile communications, this Talk will present some basic knowledge of radiation, especially nuclear radiation, covering definition, origins, applications and risks of radiations. It concludes that wireless communication does not cause nuclear radiations. The Talk is easily understandable by students of any subject background.
