Title: 5G and IoT – Separating Hype from Promise
Abstract: 5G and the Internet of Things (IoT) have entered a symbiotic hype relationship – 5G will enable IoT and IoT will provide the incremental revenue to motivate deploying 5G. Billions and billions (to quote Carl Sagan) of IoT devices are supposedly in our stars, but little is said what actually makes economic sense to deploy and what kind of deployment seems most plausible. We will look at IoT deployment models, what kind of networks they may require, and what kind of economic impact this is likely to have on network revenue. Similarly, we consider whether 5G is wise to bank on IoT to underwrite its business model, and what lessons we might learn from the previous four generations of cellular networks.

Bio:  Professor Henning Schulzrinne received his undergraduate degree in economics and electrical engineering from the Darmstadt University of Technology, Germany, his MSEE degree as a Fulbright scholar from the University of Cincinnati, Ohio, and his Ph.D. degree from the University of Massachusetts in Amherst, Massachusetts. He was a member of technical staff at AT&T Bell Laboratories, Murray Hill, and an associate department head at GMD-Fokus (Berlin), before joining the computer science and electrical engineering departments at Columbia University, New York. He is currently chair of the Department of Computer Science. He is a division editor of the Journal of Communications and Networks, and an editor of the IEEE/ACM Transactions on Networking, and the Surveys and Tutorials, and former editor of the IEEE Internet Computing Magazine and IEEE Transactions on Image Processing. He is general chair of ACM Multimedia 2004. He has been a member of the board of governors of the IEEE Communications Society and of the ACM SIGCOMM executive committee, former chair of the IEEE Communications Society Technical Committees on Computer Communications and the Internet and has served as technical program chair of Global Internet, Infocom, NOSSDAV and IPtel. He also was a member of the IAB (Internet Architecture Board). Protocols codeveloped by him are now Internet standards used by almost all Internet telephony and multimedia applications. His research interests include Internet multimedia systems, quality of service, and performance evaluation. He serves as chief scientist for SIPquest, Inc. and was a former chief scientific advisor for Ubiquity Software Corporation. He is a fellow of the IEEE and has received the New York City Mayor’s Award for Excellence in Science and Technology and the VON Pioneer Award.

Title: Systems Challenges in Building Next-Generation Wireless Networks

Abstract: Next-generation wireless networks have set ambitious goals in both throughput and latency, leveraging promising physical-layer technologies. While the mathematics of these technologies are well-known, the systems challenges toward realizing them economically can be daunting. This talk will use our experience in building three generations of massive MIMO systems as an example to illustrate some of these system challenges. Specifically, we aim to answer: how can massive MIMO systems scale up to thousands of base station antennas with commodity hardware? Importantly, as wireless networks are gradually moving away from expensive, specialized hardware, they provide a fertile ground for software systems innovations.

Bio: Lin Zhong is Professor of Electrical & Computer Engineering at Rice University. He received his B.S and M.S. from Tsinghua University and Ph.D. from Princeton University. He has been with Rice University since September 2005. At Rice, he leads the Efficient Computing Group to make computing, communication, and interfacing more efficient and effective. He and his students received the best paper awards from ACM MobileHCI, IEEE PerCom, and ACM MobiSys (3), and ACM ASPLOS. He is a recipient of the NSF CAREER Award, the Duncan Award from Rice University, and the RockStar Award from ACM SIGMOBILE. More information about his research can be found at
