Humboldt-Universität zu Berlin/IHP, Germany
Prof. Eckhard Grass received the Dr.-Ing. Degree in Electronics from the Humboldt-University Berlin, Germany, in 1993. He was a Visiting Research Fellow at Loughborough University, U.K., from 1993 to 1995, and a Senior Lecturer in Microelectronics at the University of Westminster, London, U.K., from 1995 to 1999. Since 1999, he has been with IHP, leading several projects on the implementation of wireless broadband communication systems. E. Grass is Team Leader of the Wireless Broadband Communications Group at IHP and Professor at the Department of Computer Science at Humboldt-University Berlin. E. Grass has published about 80 papers at international conferences and in international journals. He was actively involved in the definition of the international 60 GHz standards IEEE802.15.3c and IEEE802.11ad. Since 2014 he is actively involved in the definition and development of 5G, coordinating several European projects. His research topics include wireless communication systems as well as digital signal processing algorithms and architectures.

Based on limitations and shortcomings of 4G, the main requirements for the 5th generation of mobile networks (5G) are outlined. The presentation highlights key architectural features, and target parameters of 5G.
Furthermore, the main concepts for reaching the targeted key performance indicators (KPI) are outlined. This includes techniques for estimating the capacity requirements based on localization and positioning.
Moreover, technologies which are in the focus of current research, such as mmWave wireless systems, (massive-)MIMO, Hybrid Beamforming and line-of-sight (LOS-)MIMO communications are outlined. The potential of new modulation- and coding-schemes is briefly evaluated.
Based on the reviewed concepts and technologies, some important implications for Mobile Network Operators (MNO), for big companies (OEM or ‘verticals’) and the private end user are highlighted.
