The Why and How of Small Cells
Location:258 Fitzpatrick Hall
In a traditional or homogeneous cellular network, good network planning is constituted by deploying so-called macro base stations in such a way that ubiquitous coverage is guaranteed for all users while at the same time the overlap of coverage provided by different macro base stations is minimized. Heterogeneous networks fundamentally change this notion by overlaying existing networks with small cells. In this talk, we briefly review the fundamental concepts of heterogeneous networks and the signal processing techniques which allow us to harness cell splitting and offloading gains provided by small cells. We then shift our attention from the base station to the network level to explore by means of examples how cellular networks will be “greener” and easier to operate in the future.

Dr. Ralf Bendlin is a member of the technical staff at Texas Instruments Inc. (TI) and a delegate to the Third Generation Partnership Project (3GPP) where he represents TI in the standardization of current and next-generation cellular networks. After receiving his preliminary diploma from the Darmstadt University of Technology in Darmstadt, Germany in 2003 he transferred to the Munich University of Technology in Munich where he received a Bachelor's degree in 2004 and a Dipl.-Ing. (M.Sc.) Degree in 2006. In 2005, he joined the research staff of the Department of Electrical Engineering at the University of Notre Dame from which he received both a Master's degree in 2007 and a Ph.D. in 2011. All degrees are in Electrical Engineering and Information Technology. Since 2010, he has been with the Wireless Base Station Infrastructure Systems and Standards Group of Texas Instruments Inc. where he is responsible for heterogeneous network architectures and machine-type communications. His research interests lie in the field of statistical space-time signal processing in wireless communication systems with a focus on practical algorithms for cellular networks.
