Eryk Dutkiewicz, Dr., Professor of School of Computing and Communications, University of Technology Sydney

The high demand for wireless Internet including emerging Internet of Things (IoT) applications is putting extreme pressure on better utilisation of the available radio spectrum. The expected spectrum "crunch" requires highly efficient radio resource management schemes with low complexity and high responsiveness to the changing network conditions. Spectrum sharing is regarded as an essential approach to regaining access to otherwise unused spectrum and it is considered an essential component in the development of IoT and 5G networks. Spectrum sharing can be conducted at different time scales. As the time scale of the operation of spectrum sharing decreases, the possibility for utilising more available spectrum holes increases. However, the shorter time scale brings with it challenges. Efficient decisions regarding the use of spectrum sharing require accurate knowledge of the spatial and temporal spectrum use in a geographical area of interest. This knowledge can be represented in Radio Environment Maps which need to be generated efficiently and accurately. In this presentation we give an overview of the spectrum sharing concept and its emergence in standards activities for IoT and 5G networks. We also present our research on spectrum sharing including theoretical methods for efficient and accurate generation of Radio Environmental Maps and radio spectrum measurements campaigns on UTS campus in Sydney to enable Smart Building and Smart City IoT applications.

Biography:

Professor Eryk Dutkiewicz obtained his PhD (Telecommunications) from the University of Wollongong, Australia in 1996. From 1999 to 2004 he worked at Motorola Laboratories in Sydney where he managed a wireless research laboratory. During that time he was also deeply involved in the development of the popular WiFi technology. He is currently the Head of School of Computing and Communications at the University of Technology Sydney in Australia. He has held visiting professorial appointments at the Chinese Academy of Sciences, Shanghai Jiao Tong University, City University of Hong Kong and Coventry University in the UK. He is an author of over 200 research papers and several book chapters. His professional activities in recent years included participation on various International Steering Committees. He is the General Chair of IEEE VTC 2017-Spring in Sydney.
