Speaker: Benjamin Friedlander

Bio: The Speaker is Professor B. Friedlander from the Department of Electrical Engineering, University of California at Santa Cruz, where he is the director of the Wireless Communications and Signal Processing Lab. He has over 35 years of experience in wireless communications and is an internationally known expert on performance analysis of communication systems. He has consulted extensively in the industry and has been involved in several Silicon Valley wireless startups.
He is currently working on: interference mitigation techniques for reliable operation in the license exempt spectrum using WiFi, WiMax and other wireless systems; using multiple antennas for diversity and spatial multiplexing (MIMO, smart antennas); advanced techniques for fixed-point and mobile broadband; evaluating the performance of wireless systems; 2G, 3G, 4G and beyond; wireless location estimation; and sensor networks (radar, sonar, and imaging systems).
He received the B.Sc. and the M.Sc. degrees in Electrical Engineering from the Technion in Israel, and the Ph.D. degree in Electrical Engineering and M.Sc. degree in Statistics from Stanford University. He is a Fellow of the IEEE, recipient of the IEEE Third Millennium Medal, the Technical Achievement Award of the IEEE Signal Processing Society, and various awards for papers published in the professional literature.

Title: Wireless Facts and Fiction

Abstract: WiFi, WiMax, Mesh Networks, Smart Antennas, OFDM, UWB, CDMA: The proliferation of wireless systems and technologies continues to generate tremendous amounts of excitement and a commensurate amount of confusion and uncertainty Claims of performance breakthroughs and improvements abound, making it difficult to sort out fact from fiction.
This talk focuses on the performance of the physical layer of wireless communication systems, the tradeoffs and limits of throughput/capacity and range/coverage of broadband wireless access systems will be discussed. We take some of the common performance claims made in the industry regarding 802.11, 802.16 in its various flavors, and other broadband access technologies, and analyze them to address questions such as: What do these claims really mean? How credible are they? How can we make useful comparisons between different systems? We identify some of the questions you should always ask when someone is trying to sell you on a new and improved wireless technology.
The talk will cover some of the basic physical laws governing all wireless systems, how they shape wireless broadband access deployments, and what they tell us about which wireless technologies are more likely than others to be successful in the long run.
