报告人简介:

  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.

Abstract:

  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.

内容简介:

  移动通信需要使用无线频谱,根据信息论,传输频率越高数据速率也会越大。人们在享受无线网络高速率的同时又担心辐射对身体的影响。这个讲座将从无线移动通信的基本原理和演进出发,介绍无线频谱及其在5G移动通信中的应用。然后,我们介绍辐射(尤其是核辐射)的基本知识,包括核辐射的定义、来源、用途和危害;并澄清无线通信和核辐射的关系。本讲座属于科普性质,适合于任何学科的师生。
