An Interference Analysis Framework (IAF) for Spectrum Sharing Feasibility and Coexistence Determination

Abstract (Summary)

Due to recent increases in mobile broadband services by consumers, the Federal Communications Commission (FCC) is compelled to make more spectrum available for commercial use. The FCC spectrum-service rulemaking process does not formally assess risk of interference, apply statistical distributions, or recommend coexistence testing. The methodology developed in this dissertation proposes a framework that applies risk, statistics, and coexistence testing and demonstrates how spectrum regulatory decision-making processes would benefit from using a more technically defensible approach. Allowing new systems into a spectrum band can cause interference to the operating incumbent users but preventing new commercial spectrum systems can have negative economic and technological repercussions. Therefore, carefully assessing the effects of a more heavily used spectrum by treating analytical spectrum coexistence testing metrics as distributions can lead to more information-based, data-driven decision making.

When using risk assessments, regulators’ decisions will improve to include results from well-engineered and transparent spectrum coexistence testing accounting for measurement uncertainties with translations to real-world deployments by accounting for all applicable variabilities.
