Kate Harrison

Ph.D. graduate, Electrical Engineering and Computer Science, UC Berkeley

I'm a Ph.D. graduate of UC Berkeley. My research is in the area of policy for the TV whitespaces. My advisor is Anant Sahai.

I am perhaps best-known for my whitespace maps. Published in our IEEE DySpAN 2010 paper, these were among the first visualizations that researchers had of the vast whitespace opportunity. Below you see a map whose colors represent the number of 6-MHz channels available for unlicensed use across the United States. Since then, I have continued to explore spectrum policy using an empirical approach.
