Weekly Seminar Series: “Feasibility of mmWave communication on dense 4G outdoor deployments”

ABSTRACT:

The development of 5G cellular networks is driven by increasingly diverse requirements, such as 10-fold increase in data rates, few milliseconds latency, and a huge number of connections emerging from the rise of the Internet of Things. This 5G progress is motivating some fundamental changes in the existing architecture of the 4G cellular networks. Yet, complete renewal of the current networks is not reasonable neither from economic perspective nor from technical aspects. It is therefore important to consider the potential of 5G technology components on top of 4G, not as a standalone mobile system. Accordingly, we consider the usage of mmWave access as an amendment for the 4G heterogeneous network. In the presentation, special focus will be in the outdoor small cell deployment. At the beginning of the presentation, a brief introduction to the work carried out in Aalto University Department of Communications and Networking will be given.

SPEAKER:

Jyri Hämäläinen received his M.Sc. and Ph.D. degrees from University of Oulu, Finland, in 1992 and 1998, respectively. From 1999 until the end of 2007, he was a senior specialist and program manager in Nokia, where he worked with various aspects of mobile communication systems and 3GPP standardization. Since 2008, Hämäläinen has been a Professor in Aalto University, School of Electrical Engineering, where he is currently serving as a Dean. His research interests cover mobile and wireless systems, with special focus on dynamic and heterogeneous networks including e.g. small cells, multi-antenna transmission and reception techniques, scheduling and relays. Prof. Hämäläinen is author or co-author of over 190 scientific publications and 36 US patents or patent applications.
