ABSTRACT: Cognitive Radio has been suggested as a method for promoting more efficient spectrum usage by using spectral white space on an unlicensed basis. The IEEE802.22 working group standardized the first cognitive radio based wireless system in July 2011, also known as the Wireless Regional Area Network (WRAN).   IEEE802.22 operates opportunistically on an unlicensed basis in television band white space TVWS. Subsequently, the cognitive radio standard IEEE802.11af, also known as Super WiFi, was approved in February 2014, for operation in TVWS. This seminar discusses some key challenges associated with the deployment of unlicensed cognitive radio devices in TVWS, in terms of both technical and regulatory issues. The seminar first presents results from an interference analysis of TVWS, whereby the interference temperature of digital television (DTV) receivers was determined. It is shown that WRAN networks, in typical deployments, can potentially cause harmful interference to DTV receivers operating near the defined DTV broadcast service contours. Super WiFi devices are shown to have greater potential for operation in TVWS on a non-interfering basis.

BIOGRAPHY: Dr. Gordon L. Stüber received the B.A.Sc. and Ph.D. degrees in Electrical Engineering from the University of Waterloo, Ontario, Canada, in 1982 and 1986 respectively. In 1986, he joined the School of Electrical and Computer Engineering, Georgia Institute of Technology, Atlanta, GA, where he holds the Joseph M. Pettit Chair in Communications.

Dr. Stüber is author of the textbook Principles of Mobile Communication. He was co-recipient of the Jack Neubauer Memorial Award in 1997 for the best systems paper published in the IEEE Transactions on Vehicular Technology. He became an IEEE Fellow in 1999 “for contributions to mobile radio and spread spectrum communications.” He received the IEEE Vehicular Technology Society James R. Evans Avant Garde Award in 2003 “for his contributions to theoretical research in wireless communications.” In 2007, he received the IEEE Communications Society Wireless Communications Technical Committee Recognition Award (2007) “for outstanding technical contributions in the field and for service to the scientific and engineering communities.”

Dr. Stüber served as Technical Program Chair for the 1996 IEEE Vehicular Technology Conference (VTC’96), Technical Program Chair for the 1998 IEEE International Conference on Communications (ICC’98), General Chair of the Fifth IEEE Workshop on Multimedia, Multiaccess and Teletraffic for Wireless Communications (MMT’2000), General Chair of the 2002 IEEE Communication Theory Workshop (CTW’02), and General Chair of the Fifth YRP International Symposium on Wireless Personal Multimedia Communications (WPMC’2002). He is a past Editor for Spread Spectrum with the IEEE Transactions on Communications (1993-1998), and a past member of the IEEE Communications Society Awards Committee (1999-2002). He served as an elected Member-at-Large on the IEEE Communications Society Board of Governors (2007-2009), and is currently an elected member of the IEEE Vehicular Technology Society Board of Governors (2001-2018). He received the IEEE Vehicular Technology Society Outstanding Service Award in 2005.
