Query: Quantified Spectrum Sharing: Motivation, Approach, and Benefits   A significant portion of the radio frequency spectrum remains underutilized
with exclusive and static allocation of spectrum. The growing demand for
spectrum has spurred a need for dynamic spectrum sharing paradigm. While the
new dynamic spectrum sharing paradigm helps to improve utilization of the
precious spectrum resource, there exist several obstacles on the technical,
regulatory, and business fronts for the adoption of the new paradigm.
  In this paper, we investigate the limitations of the existing techniques and
argue for quantified approach to dynamic spectrum sharing and management. We
introduce a quantified approach to spectrum sharing based on defining and
enforcing quantified spectrum-access rights. By discretizing the spectrum-space
in the time, space, frequency dimensions, this approach enables quantifying the
spectrum consumed by individual transceivers. It enables defining and enforcing
a quantified spectrum-access policy in real-time. The proposed quantified
approach brings in simplicity, precision and efficiency in terms of spectrum
commerce and operations while addressing the key technical and regulatory
challenges.
