Cellular IoT

Olof Liberg is a Line and Program Manager at Ericsson’s department for Standards & Technologies. Olof joined Ericsson in 2008 and has specialized in the design and standardization of cellular radio access technologies. He is currently leading a team focused on radio and spectrum standardization and Ericsson’s 3GPP radio access network standardization program. Olof holds a Bachelor’s degree in Business and Economics and a Master’s degree in Engineering Physics, both from Uppsala University. He has actively participated in the work of several standardization bodies, such as 3GPP, ITU-R, and ETSI. He was the Chairman of 3GPP TSG GERAN and its Working Group 1, during the 3GPP study on new radio-access technologies for the Internet of Things leading up to the specification of Narrowband IoT (NB-IoT). Olof is one of the authors behind the first and second edition of the book Cellular Internet of Things (Elsevier) and has coauthored several academic publications and contributed to more than 100 US patents.

Johan Bergman is a Master Researcher at Ericsson Business Unit Networks. He received his Master of Science degree in Engineering Physics from the Chalmers University of Technology in Sweden. He joined Ericsson in 1997 to work with base station receiver algorithm design and performance, and since 2005, he has been working with 3G/4G/5G physical layer standardization in 3GPP TSG RAN Working Group 1. As the Rapporteur of the 3GPP TSG RAN Work Items for LTE for Machine-Type Communication (LTE-MTC) in Releases 13 through 16 and for NR RedCap in Releases 17 and 18, he has led the technical work to standardize new features dedicated to IoT. He was a corecipient of Ericsson’s Inventor of the Year award for 2017.

Y.-P. EricWang is a Research Leader at Ericsson Research. He holds a PhD degree in Electrical Engineering from the University of Michigan, Ann Arbor. In 2001 and 2002, he was a member of the Executive Committee of the IEEE Vehicular Technology Society and served as the society’s Secretary. Dr.Wang was an Associate Editor of the IEEE Transactions on Vehicular Technology from 2003 to 2007. He has been a Technical Coordinator at Ericsson Research in the area of Internet of Things (IoT) connectivity. Dr. Wang was a corecipient of Ericsson’s Inventor of the Year award in 2006. He has contributed to more than 200 US patents and more than 50 IEEE articles.

Andreas Höglund has a Master of Science in Engineering Physics (2002) and a PhD in Condensed Matter Physics from Uppsala University (2007). He is a Principal Researcher at Ericsson Research and has, since he joined in 2008, worked on the L2/L3 of cellular networks (High Speed Packet Access (HSPA), LTE, New Radio (NR), system simulations, EU research projects, etc.). After the standardization of 3GPP LTE-MTC (Cat-M1) and NB-IoT in 2015, and the later evolution thereof, he has come to focus on cellular IoT networks. His recent work includes 3GPP standardization of Rel-17 RedCap and small data transmission (SDT), Rel-18 and Rel-19 eRedCap, small data transmission, wakeup receiver (WUR), Ambient IoT, and IoT research for 6G. He has contributed to more than 30 academic papers and over 100 US patents.

Mohammad Mozaffari is a Senior Researcher at Ericsson Research, Silicon Valley, USA. He received his PhD degree in Electrical and Computer Engineering from Virginia Tech in 2018. His research interests span diverse areas, including 5G and 6G wireless networks, Uncrewed Aerial Vehicle (UAV) and drone communications, IoT, and machine learning. He has been actively contributing to 3GPP standardization for NB-IoT, LTE-MTC, RedCap, and wake-up radio. He is the recipient of several awards, including the IEEE ComSoc Young Author Best Paper Award, the IEEE Communications Society Award for Advances in Communication, and the Outstanding PhD Dissertation Award. He is the author of a book on UAV communications and over 40 IEEE journal and conference papers. He is currently an Associate Editor of the IEEE Vehicular Technology Magazine and the IEEE Transactions on Machine Learning in Communications and Networking. He is a Senior Member of the Institute of Electrical and Electronics Engineers (IEEE).
