Cellular Internet of Things

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.Mårten Sundberg is a researcher at Ericsson Business Unit Networks, with a previous position as a Senior Specialist in GSM radio access technology. He joined Ericsson in 2005 after receiving his master's degree in Engineering Physics from Uppsala University. As Rapporteur of the 3GPP Work Item on EC-GSM-IoT he was leading the technical work to standardize the new GSM-based feature dedicated for Internet of Things. In 2016, he started leading the work towards URLLC for LTE, being a Rapporteur for the Work Item introducing shortened TTI and shorter processing times. Apart from being active in the 3GPP standardization body, Mårten has also worked for many years in ETSI, harmonizing radio requirements in Europe.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.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.Joachim Sachs is a Principal Researcher at Ericsson Research. After studies in Germany, Norway, France and Scotland he received a diploma degree in electrical engineering from Aachen University (RWTH), Germany, and a PhD degree from the Technical University of Berlin. He joined Ericsson in 1997 and has worked on a variety of topics in the area of wireless communication systems, and has contributed to the standardization of 3G, 4G and 5G. Since 1995 he has been active in the IEEE and the German VDE Information Technology Society (ITG), where he is currently co-chair of the technical committee on communication networks. In 2009 he was a visiting scholar at Stanford University, USA.
