  1. Spectrum sharing, including dynamic spectrum sharing, is arguably the most significant overarching feature of the new era of spectrum management. The emphasis on sharing spectrum recognizes the importance of balancing the needs of different users of an exceptionally valuable resource. Despite the equitable features of spectrum sharing, what has been underemphasized in spectrum management is its colonial features from the perspective of Native Nations. This paper proposes ways to decolonize dynamic spectrum sharing and, in the process, improve prospects for a new spectrum era that recognizes Native Nations as collaborators in the American system of spectrum management.

  2. A simple “RF-flashlight” (or ground-to-satellite) interference testbed is proposed to experimentally verify (i) real-time geofencing (RTG) for protecting passive Earth Exploration Satellite Services (EESS) radiometer measurements from 5G/6G mm-wave transmissions, and (ii) ground-to-satellite propagationmodels used in the interference modeling of this spectrumcoexistence scenario. RTG is a stronger EESS protectionmechanism than the current methodology recommended by theITU based on a worst-case interference threshold whilesimultaneously enabling dynamic spectrum sharing and coexistencewith 5G/6G wireless networks. Similarly, verifying moresophisticated RF propagation models that include ground topology,buildings, and non-line-of-sight paths will provide better estimatesof interference than the current ITU line-of-sight model and, thus,a more reliable basis for establishing a consensus among thespectrum stakeholders.
