THOMAS AND MARY LU JUDD DISTINGUISHED LECTURE SERIES
Title: “A Better Way to Find a Cellular Phone That Dials 911”
Speaker: Prof. Gregory D. Durgin, Georgia Tech
Friday, September 28th
This talk will discuss new received-signal strength location techniques for finding E911 cellular phone users. We employ propagation modeling along with basic propagation measurements that the handset makes as part of its existing hand-off algorithm. With an extensive measurement campaign, we demonstrate FCC-compliant position location statistics on the campus of Georgia Tech in midtown Atlanta and other urban environments for a network with a majority of indoor users. Many of the results and techniques discussed have been incorporated into the Polaris Wireless E911 position location system that has been deployed across the US for increased public safety.
Gregory D. Durgin joined the faculty of Georgia Tech's School of Electrical and Computer Engineering in Fall 2003. He received the BSEE (96), MSEE (98), and PhD (00) degrees from Virginia Polytechnic Institute and State University. In 2001 he was awarded the Japanese Society for the Promotion of Science (JSPS) Post-doctoral Fellowship and spent one year as a visiting researcher with Morinaga Laboratory at Osaka University. In 1998 he received the Stephen O. Rice prize (with coauthors Theodore S. Rappaport and Hao Xu) for best original journal article in the IEEE Transactions on Communications. Prof. Durgin also authored Space-Time Wireless Channels, the first textbook in the field of space-time channel modeling. Prof. Durgin founded the Propagation Group (http://www.propagation.gatech.edu) at Georgia Tech, a research group that studies radiolocation, channel sounding, direction finding, backscatter radio, RFID, and applied electromagnetics. He is a winner of the NSF CAREER award as well as numerous teaching awards, including the Class of 1940 Howard Ector Outstanding Classroom Teacher Award (2007). He is an active consultant to industry.
