Cognitive Radio: Current Status and Future Technology Challenges at Motorola
David Borth
Motorola, Inc.

Cognitive radio has matured rapidly since the term was coined in 1999. In 2009, cognitive operation in the US television white space (TVWS) has been enabled through FCC regulation. This is just the first of many potential cognitive wireless system opportunities that will connect underserved markets, enhance public communication, and affect everyday life. A vision of the current and future cognitive radio systems will be presented, with the role of key enabling technologies, such as geo-location databases and cooperative sensing. Some ramifications of the November 2008 final FCC rules on TVWS systems will also be presented.

Dr. David Borth is Corporate Vice President and Chief Technology Officer for the Government and Public Safety business of Motorola Inc. He also is the director of Advanced Technology, Standards and Common Engineering within this business. In this role, he is currently responsible for a number of activities including software-defined radio, cognitive radio, the IC platform for all portable devices and the next generation architecture for future public safety systems. Dr. Borth joined Motorola in 1980 as a member of the Corporate R&D organization in Schaumburg, IL. He became the manager of the Communication Systems Research Laboratory in 1990 and led the Wireless Access Research Center of Excellence within Motorola Labs until August 2005. In September 2005 he was appointed to his current position. For the past 28 years, he has made significant contributions to numerous wireless and wireline technologies including Motorola's implementations of GSM, TDMA and CDMA digital cellular systems. Most recently he has led the broadband wireless research work focusing on the development of key technologies for future wireless systems including 802.16e/WiMAX, LTE, and 4G systems.

From 2000-2003 he was a member of the Computer Science and Telecommunications Board of the National Research Council. In 2005 he was appointed a member of the FCC's Technological Advisory Council (TAC). In 2006 he was appointed to the U.S. Department of Commerce Spectrum Management Advisory Committee (CSMAC). He was reappointed to the CSMAC in January 2009. He also serves as a member of the Telecom Industry Association's Research Division. Dr. Borth is a member of Motorola's Science Advisory Board and has been elected a Dan Noble Fellow, Motorola's highest honorary technical award. He has been issued 31 patents to date and has authored or co-authored chapters of five books in addition to 25 publications. He received the Distinguished Alumnus Award from the University of Illinois Electrical and Computer Engineering Alumni Association. He is a Fellow of the Institute of Electrical and Electronics Engineers (IEEE), a member of the National Academy of Engineering, and a Registered Professional Engineer in the State of Illinois. Dr. Borth received his BS, MS, and PhD degrees in electrical engineering from the University of Illinois at Urbana-Champaign. Previously, he was a member of the Technical Staff of the Systems Division of Watkins-Johnson Co., Palo Alto, Calif. and an assistant professor in the School of Electrical Engineering, Georgia Institute of Technology, Atlanta, GA.
