The measurements were made at the Illinois Institute of Technology (IIT), Chicago, Illinois.The IIT Tower has an unobstructed view in all directions as shown in Figure. A detailed explanation of the site, measurement setup and data collection is listed in [1]. Several spectrum occupancy measurements were performed in Chicago and proposals for long-term studies in multiple locations have been made from the spectrum observatory in these papers [1-4]

I did this work when I was a Research Assistant at Wireless Network and Communications Research Center (WiNCom) from Jan 2016 – Aug 2017.

Objective: To study the utilization of the wireless spectrum, in order to come up with schemes for optimal usage through different models. To collect spectrum data from different sites and analyzing the data.
