Future energy–efficient wireless communication

The overall traffic volume in wireless communication networks has grown tremendously in recent years, fueled primarily by an enormous uptake in the use of mobile broadband, a growth that is expected to continue. In addition to mobile broadband, the transformation to a fully networked society where anything that benefits from being connected will be connected, will further accelerate the usage of wireless access. To handle this traffic increase in an affordable manner, as well as to meet the general quest for a sustainable society, it is important to continuously improve the energy efficiency of wireless networks. In this talk, we will discuss some of the technologies and principles relevant for the evolution of 4G and 5G from an energy perspective such as ultra-lean design, micro-sleep, and massive beamforming.

Stefan Parkvall (senior member, IEEE) is currently a principal researcher at Ericsson Research, working with research on future radio access. He is one of the key persons in the development of HSPA, LTE and LTE-Advanced radio access and has been deeply involved in 3GPP standardization for many years. Dr Parkvall is a senior member of the IEEE, served as an IEEE Distinguished lecturer 2011-2012, and is co-author of the popular books “3G Evolution – HSPA and LTE for Mobile Broadband” and “4G – LTE/LTE-Advanced for Mobile Broadband”. He has numerous patents in the area of mobile communication. In 2005, he received the Ericsson “Inventor of the Year” award, in 2009 the Swedish government’s Major Technical Award for his contributions to the success of HSPA, and in 2014 he and colleagues at Ericsson was nominated for the European Inventor Award, the most prestigious inventor award in Europe, for their contributions to LTE. Dr Parkvall received the Ph.D. degree in electrical engineering from the Royal Institute of Technology in 1996. His previous positions include assistant professor in communication theory at the Royal Institute of Technology, Stockholm, Sweden, and a visiting researcher at University of California, San Diego, USA.
