Special Temporary Authority application - Explanation
Please explain in the area below why an STA is necessary:
As part of the NSF SII-NRDZ program, the University of Utah (UofU) in Salt Lake City, Utah, is using the POWDER platform to prototype an end-to-end radio dynamic zone (RDZ), i.e., the POWDER-RDZ. In addition to implementing a prototype Zone Management System (ZMS), called OpenZMS, POWDER-RDZ is exploring a number of practically realizable spectrum sharing use cases that would illustrate technical aspects of an RDZ, as well as explore regulatory aspects of spectrum sharing. In this context, one of the use cases the University of Utah is exploring is the feasibility of an RDZ safely sharing spectrum with radar systems operating in the 2.7-2.9 GHz range. (We have recently received an NSF award to explore this use case -- Award Number: 2434086.) Concretely, in the case of POWDER-RDZ, a spectrum sharing experiment would involve testing RF equipment in the POWDER platform sharing the spectrum range with the federal radar systems in our vicinity.

Special Temporary Authority application - Purpose of Operation
Please explain the purpose of operation:
To obtain feedback on the feasibility of the approach and the steps required in realizing it, the University and NTIA undertook a collaborative effort to perform a sensitivity analysis of the radar systems in the context of test equipment at the POWDER facility, and based on that analysis propose an approach towards a possible spectrum sharing experiment. In summary the University proposes a multi-step process whereby we will completely avoid the spectrum range associated with the ASR-9 system at the Salt Lake City airport and progress through a carefully controlled series of experiments to make use of the bottom part of the band (2.7-2.8 GHz). (In essence starting with a few low power transmitters and ending with several nodes transmitting at modest power levels.)
