Abstract: The frequency range from 0.1-1 THz is of great interest for beyond 5G (B5G) wireless communications, due to the enormous amount of (currently fallow) spectrum in that band. In order to assess the potential of this band, and anticipate possible pitfalls, measurement and modeling of the corresponding propagation channels is the vital first step. This is particularly relevant since many of the dominant propagation effects are significantly different from those at the traditional cm-wave frequencies (i.e., microwave range). This talk will first provide a review of physical propagation processes and how they are distinct at THz channels. We then proceed to the measurement techniques, which are considerably more challenging than at lower frequencies, as well as deterministic (ray tracing/launching) methods for high frequency ranges. We will then review key measurement results, emphasizing outdoor environments, for which we recently performed the first directionally resolved long-distance (up to 100m) measurements. Throughout the talk, impact of the propagation on the system design will be emphasized.
Biography: Andreas F. Molisch received his PhD and habilitation from TU Vienna in 1994 and 1999, respectively. After 10 years in industry he joined the University of Southern California, where he is now the Solomon Golomb – Andrew and Erna Viterbi Chair Professor. His research interest is wireless communications, with emphasis on wireless propagation channels, multi-antenna systems, ultrawideband signaling and localization, novel modulation methods, caching for wireless content distribution, and edge computing. He is the author of four books, 21 book chapters, more than 260 journal papers, 360 conference papers, as well as 70 granted patents; his work has been cited more than 50,000 times. He is a Fellow of the National Academy of Inventors, IEEE, AAAS, and IET, as well as Member of the Austrian Academy of Sciences and recipient of numerous awards.
