Letter to FCC on Use of Spectrum Bands Above 24 GHz For Mobile Radio Services

NTIA submits the enclosed information for purposes of supplementing the record in the above-referenced proceeding. The rules and polices the FCC intends to adopt in this proceeding will unlock access to higher frequency bands (i.e ., the "spectrum frontier" bands) for fixed and mobile services by establishing a flexible regulatory framework for several bands in the millimeter wave range in order to facilitate the development and deployment of, for example, so-called "5G" services and applications.  The enclosed teclmical information: (1) summarizes current and projected federal agency operations in and adjacent to the specific bands identified in the Spectrum Frontiers NP Rlvf and supports the proposed teclmical rules aimed at protecting them; (2) supplements teclmical analysis and data NTIA previously submitted to the Commission in other proceedings involving some of these bands; (3) supports a flexible and i1movative sharing framework in the 37-38.6 GHz band; and (4) addresses issues related to the protection of the passive services in the 64-71 GHz band.
