abstract

This work seeks to lay the groundwork for the dynamic sharing of the federally reserved spectrum between 2700MHz and 2900MHz, first by understanding the spectrum’s existing users and their use cases. The actual spectrum usage along the northern Wasatch Front near the University of Utah was studied to develop an accurate understanding of how the spectrum is being used on the ground. Then, a proof-of-concept radar analyzing multi-channel occupancy detector was designed to detect and report on live radar channel occupancy dynamically. The system’s efficacy is verified through a series of tests to see radar systems accurately in real-time. Lastly, this thesis proposes the integration of the proof-of-concept system into the POWDER Zone Management System, which would create an end-to-end system to enable prospective secondary users into the reserved federal channel with the approval of incumbent operators.
