As directed by the 2023 National Spectrum Strategy (NSS), the frequency band 18.1-18.6 GHz (the “18 GHz band”) was identified for study for expanded federal and non-federal satellite operations, consistent with the United States position at the International Telecommunication Union’s (ITU’s) 2023 World Radiocommunication Conference (WRC-23). WRC-23 concluded on December 23, 2023, adding co-primary space-to-space allocations for the intersatellite service (ISS) in this band.

Executive Summary

The National Telecommunications and Information Administration (NTIA) concludes in this report that it is technically feasible to share the 1675-1680 MHz band used by the National Oceanic and Atmospheric Administration (NOAA) for transmission of time-sensitive satellite data with commercial wireless services.
