Kate Harrison

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

I'm currently a fifth-year graduate student at 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.


The code for the results in most publications can be found at github.com/kate-harrison/whitespace-eval.
