Dr. Timothy X Brown, Professor in Electrical, Computer, and Energy Engineering Carnegie Mellon University in Rwanda held a distinguished lecturer at the iHub in Nairobi, Kenya on Thursday the 11th April 2013 at 6 PM. It explored Wireless technology having the potential to expand broadband access to many people with modest investment.

He explored the options of where the critical wireless spectrum would originate. 
The fact that all useful spectrums are already allocated while paradoxically most spectrum is unused. He went further to expound how this paradox can be shattered with a new technology, dynamic spectrum access.


Professor Timothy X Brown set the stage for a discussion on how dynamic spectrum access presents both technical challenges that need to be solved while also creating opportunities for regulators to unlock the potential of their country's spectrum. He also presented examples of its use including access to the unused "white spaces" in the television band to provide broadband.

Timothy X Brown is a Professor in Electrical, Computer, and Energy Engineering and served as Director of the Interdisciplinary Telecommunications Program at the University of Colorado, Boulder. He received his B.S. in physics from Pennsylvania State University and his Ph.D. in electrical engineering from California Institute of Technology in 1990.

His research interests include adaptive network control, machine learning, and wireless communication systems.  His current research funding includes NSF, FAA, DOE, and industry. Projects include the role of mobility in network control of unmanned aircraft, denial of service vulnerabilities in wireless protocols, spectrum policy frameworks for cognitive radios, and indoor wireless network performance.

He is a recipient of the NSF CAREER Award, and the GWEC Wireless Educator of the Year Award.
