Fredrik Tillman received his M.Sc. and Ph.D. degrees in Electrical Engineering from Lund University in 2000 and 2005
respectively. After graduation he joined Ericsson Mobile Platforms and participated in the first cellular modem CMOS radio
development in Sweden and US before moving on to the research branch of the company. Today he is heading a
department at Ericsson Research with focus on integrated radio circuit design for both cellular infrastructure and device
connectivity. Besides being responsible for internal R&D activities, Fredrik is active in the European research community
and has been the Ericsson driver for multiple collaboration projects within the Horizon 2020 framework. He is today the
technical manager for the COREnext project. Since 2022, Fredrik is serving as a board member of the Swedish strategic
innovation program Smarter Electronic Systems to increase competitiveness and growth in Swedish industry.
In the quest for more network capacity, frequencies beyond current mmWave deployments have started to climb the hype curve. But will this research green field become applicable to the mobile network industry in the future? Is it enough having radio frontend components available, or must the network realization as we know it today be redefined? This talk will elaborate on predicted use cases for 6G and how the cellular radio roadmap tries to meet assumed requirements. Will sub- THz frequencies be part of this journey or simply remain as a hype?
