Pekka Kyösti received the M.Sc. degree in mathematics and D.Sc. (Hons.) in Telecommunications from the University of Oulu, Finland, in 2000 and 2018, respectively. From 1998 to 2002, he was with Nokia Networks. From 2002 to 2016, he was with Elektrobit Ltd/Anite Ltd. He was moved to Keysight Technologies Finland Oy along the acquisition in 2016. Since 2002, he has been involved in radio channel measurements, estimation and modelling. He has contributed to numerous widely adopted channel models like, e.g., WINNER, IMT-Advanced, and METIS, as well as to development and standardization of radiated testing in fading radio conditions. Currently he is involved in activities aiming at 5G and beyond 5G systems at Keysight Technologies Finland Oy and at Centre for Wireless Communications (CWC), University of Oulu. His research interests are radio channel characterization and modelling, emulation of multi-dimensional fading radio channel, and over-the-air testing of radio devices.

Update: “Radio channel characterization for 5G and beyond”

Abstract: In this talk we briefly revisit radio channel modelling for 5G systems. We compare FR1 and FR2 propagation characteristics in general. Especially the multitude of standardized 3GPP models, their application areas and key features, will be introduced. Currently the models are actively used by the industry for performance evaluations of various functionalities. In frequency, the standard 5G channel models are defined for up to 100 GHz. Now in the initiated 6G research also higher frequencies become interesting for radio communications and related applications, such as imaging, sensing, and substance detection. The latter part of the talk extends beyond 5G frequencies to upper millimetre-wave and terahertz bands. We sketch peculiarities of radio propagation at mm-wave and THz frequencies and present some example channel measurements to illustrate differences between the 5G frequencies and the potential 6G frequencies. Furthermore, we discuss the capability of upper millimetre-wave and terahertz frequency bands to enable wireless communications by introducing RF related challenges and a link budget evaluation for a 300 GHz system.
