Since February 1, 2023, I am officially retired from my faculty position at KTH – The Royal Institute of Technology, in Stockholm, Sweden. However, as professor emeritus, I continue some of my research projects in HF communications at KTH. I was professor in Radio Communications at KTH between 1989 and 2022. I was co-founder and long-time director of Wireless@KTH, the Center for Wireless Systems at KTH. I used to serve as the Scientific Director of that center until 2017 when the center was closed. I still belong to the Radio Communication Systems lab which I led from 1989 – 2017. The lab is now part of the the Division of Communication Systems. 2013-2017 I was head (Dean) of the KTH School of Information and Communication Technology. From 2017, I was leading the merger of the three schools at KTH and became the Head (Dean) of the new School of Electrical Engineering and Computer Science (EECS) at KTH, a post that I held 2018-2020.
Besides my activities at KTH I was a board member of PTS, the Swedish National Telecom Regulator between 2007 -2021.
Since 2001 I am a member of the Royal Academy of Engineering Sciences (IVA) ,
In 2014 I was appointed Honorary Doctor at Alto University, Finland
My research interest have been focused on the future of Wireless Systems – Infrastructures and Services. Managing the “Data Tsunami” with respect to technologies, infrastructure economics as well as spectrum and energy management I see as one of our greatest challenges ahead. Currently I have returned to my old research interest, which is HF communication systems.
Look at some recent presentations I gave about my latest research
Our latest textbook “Fundamentals of Mobile Data Networks” was published by Cambridge University Press in March 2016. 
If your are one of those looking for prior art to fight ridiculous patents in active networking, software defined networks and similar stuff that seems to be reinvented every odd decade, you can save some time by looking at some of my ancient work as Ph.D. student: Zander1981,
