Not only are communication data rates increasing rapidly and exponentially, but they are also shifting from wired to wireless systems, making wireless technology increasingly important in our lives and societies. ?As a result, it is becoming increasingly difficult to make large blocks of spectrum available for new purposes, perhaps threatening this expansion of wireless communications. ?There are solutions to this problem, but many require a fundamental shift away from the way we have been managing spectrum and protecting wireless systems from interference for the last eighty years. ?As it becomes more difficult to give each wireless system exclusive access to a block of spectrum, we must find new ways to for systems to share spectrum without harmful interference, which will lead to changes in both wireless technology and spectrum regulation and policy. ?This talk will first present some of the general challenges and opportunities of spectrum sharing. It will then focus on specific issues of spectrum sharing, most notably the opportunities and challenges of sharing spectrum with radar systems. ?It will be shown that it is possible to offer broadband services in spectrum that is considered by traditional standards to be 100% utilized by rotating radar, with no harmful interference to radar. ?Moreover, these broadband services offer quality of service that is appropriate for most Internet traffic, but not for a few real-time applications such as voice over IP (VOIP).


Jon Peha is a Full Professor at Carnegie Mellon University. He served in the U.S. Government in 2008-2011, first as the Chief Technologist of the Federal Communications Commission, and then at the White House as Assistant Director of the White House Office of Science & Technology Policy where he focused on Communications and Research. At Carnegie Mellon, he is a Professor in the Dept. of Engineering & Public Policy and the Dept. of Electrical & Computer Engineering, and former Associate Director of the university's Center for Wireless & Broadband Networking. He has served as Chief Technical Officer for three high-tech companies, and a member of technical staff at SRI International, AT&T Bell Laboratories, and Microsoft. He has addressed telecom and e-commerce policy on legislative staff in the House Energy & Commerce Committee and the Senate, and helped launch and lead a US Government interagency program to assist developing countries with information infrastructure. His research spans technical and policy issues of information networks, including spectrum management, broadband Internet, wireless networks, video and voice over IP, communications for emergency responders, universal service, secure Internet payment systems, online dissemination of copyrighted material, privacy and security. Dr. Peha holds a PhD in electrical engineering from Stanford, and a BS from Brown. He is an IEEE Fellow, an AAAS Fellow, and a winner of the IEEE TCCN Publication Award for career ?contributions to techno-economic analysis of spectrum allocation policies? and the FCC's "Excellence in Engineering Award.?
