The demand for wireless data is projected to continue to rapidly grow. Meeting this demand will require that wireless data services have access to additional RF spectrum. It is widely recognized that this in turn will require new approaches for spectrum management. In particular various mechanisms for sharing spectrum among multiple firms are attracting much interest.  While such shared spectrum can allow for market expansion, its addition will also influence the competition among wireless service providers and greater sharing can increase the congestion seen by consumers of these services.  In this talk we present several stylized models to provide insight into how different approaches to spectrum sharing may impact economic welfare. These are based on game theoretic models for price or quantity competition among firms with congestible resources, where here the congestion depends in part on how spectrum is shared.


Randall Berry joined Northwestern University in 2000, where he is currently a Professor in the Department of Electrical Engineering and Computer Science. He received the M.S. and PhD degrees in Electrical Engineering and Computer Science from MIT in 1996 and 2000, respectively. His undergraduate education was at the University of Missouri-Rolla, where he received the B.S. degree in Electrical Engineering in 1993. In 1998 he was on the technical staff at MIT Lincoln Laboratory in the Advanced Networks Group. Dr. Berry is the recipient of a 2003 CAREER award from the National Science Foundation.  He is an IEEE Communications Society Distinguished Lecturer for 2013-14. He has served as an Editor for the IEEE Transactions on Wireless Communications from 2006 to 2009, and an Associate Editor for the IEEE Transactions on Information Theory from 2009 to 2011, in the area of communication networks. He has served on the program and organizing committees of numerous conferences including serving as the co-chair of the 2012 IEEE Communication Theory Workshop and a technical co-chair of 2010 IEEE ICC Wireless Networking Symposium. He is an IEEE Fellow.
