NTIA on Board With FCC's Proposed 60 GHz Rules
The FCC got NTIA's signoff Wednesday on a Further NPRM approved by commissioners a year ago proposing revised rules for short-range radars in the 60 GHz band (see 2107130066). NTIA noted it had asked FCC to further study the effect…

of field disturbance sensor technical characteristics and deployment densities on passive earth-exploration satellite service before adopting rules for the 57-59.3 GHz portion of the band. “We believe sufficient analysis has been done such that NTIA would have no objection to the Commission proceeding with the adoption of proposed rules,” said a filing in docket 21-264. NASA, the National Oceanic and Atmospheric Administration and NTIA established a technical interchange group (TIG) to study the issues raised, the filing said. “The TIG members independently collaborated on the technical analysis, reaching consensus that unlicensed devices operating under the rules proposed in the NPRM would not result in harmful interference to passive EESS sensors operating in the 57-59.3 GHz band,” NTIA said: "The high level of atmospheric attenuation that exists between transmitters on the surface of the Earth and the passive sensors in this frequency band was found to be a dominant factor towards the favorable results.”
