FCC Explores Spectrum Sharing Approaches for the 42 GHz Spectrum Band

The Federal Communications Commission launched a proceeding to consider innovative sharing models in 500 megahertz of spectrum in the 42 GHz band. This examination of sharing models in high-band spectrum could not only inform how this band might best be used—particularly by smaller wireless service providers—but also inform future uses of sharing models in spectrum management. With ever-increasing demand for wireless services and a finite supply of airwaves, it is more important than ever to focus on finding ways to share spectrum, a valuable resource. As the spectrum between 42-42.5 GHz is largely unused, the FCC proposes exploring an innovative, non-exclusive spectrum access model in this greenfield spectrum, which is ideal for experimentation due to the lack of incumbent licensees. The FCC will seek comment on three specific shared licensing approaches:

• A nationwide non-exclusive licensing approach, in which licensees coordinate specific deployment sites with a third-party database;
• A site-based licensing approach, in which licensees would apply for each deployment site directly with the FCC; and
• A technology-based sensing approach, in which operators would employ such technologies to avoid harmful interference from one another.
