COLLOQUIUM Department of Computer Science and Engineering University of South Carolina IIT's Spectrum Observatory: Lessons Learned from Four Years of Monitoring the Spectrum Occupancy in the City of Chicago Dennis A. Roberson Department of Computer Science Illinois Institute of Technology Date: October 7, 2011 Time: 1430-1530 Place: Swearingen 2A27 Abstract Spectrum is a scarce natural resource that we depend on to an ever increasing degree for our social interactions, our protection and emergency services at the national and global level and the efficient conduct of business both here and around the world. This resource is extremely valuable commanding prices in the U.S. in the range of $250,000,000 per MHz for prime spectrum property. Even the President has become directly involved in an effort to move 500 MHz of spectrum to commercial broadband providers (usually cell phone service providers) in an attempt to spur economic growth, create jobs and to help to resolve the Federal Budget deficit. Given its value and importance, surprisingly little is really known about the current usage and the trends in the spectrum occupancy in the various geographies in the U.S. and around the world. To help resolve this issue, Illinois Institute of Technology through its Wireless Network & Communications Research Center (WiNCom) developed a Spectrum Observatory to monitor the spectrum occupancy in the "Loop," the business center of the City of Chicago. The lecture will describe the implementation and operation of the Observatory and describe the various findings over the past four years of observation. The talk will also discuss the potential to use this kind of installation to assist in the implementation of next generation wireless communications systems based on dynamic spectrum access network techniques and Cognitive Radio based systems. Dennis A. Roberson is Vice Provost for Corporate Relations and Strategic Initiatives, and a Research Professor in Computer Science at Illinois Institute of Technology. In this capacity, he has responsibility for IIT's relationships with its various corporate partners and serves as the focus for the implementation of IIT's Strategic Plan. He also supports the development of new research centers, and the successful initiation and growth of IIT related technology-based business ventures. Professor Roberson is a co-founder of IIT's Wireless Network and Communications Research Center (WiNCom) and an educator in the wireless networking arena. He is also the President of Roberson and Associates, LLC, a consulting firm primarily focused on wireless technology and technology management. He serves on the governing or advisory boards of several technology-based companies and on the FCC's Technology Advisory Council and the U.S. Commerce Spectrum Management Advisory Committee. Prior to IIT, he was EVP and CTO at Motorola. Professor Roberson has an extensive corporate career including major business and technology responsibilities at IBM, DEC (now part of HP), AT&T, and NCR. He is involved with a wide variety of Technology, Educational and Youth organizations and serves as a frequent speaker at universities, companies, technical workshops, and conferences around the globe. Professor Roberson has BS degrees in Electrical Engineering and in Physics from Washington State University and a MSEE degree from Stanford.
