{"abstract":"By this Third Report and Order (R&O) the Commission amends the rules to: provide amateur and amateur-satellite operators co-primary status in the 77.5-78 GHz frequency band to ensure that future amateur station access to spectrum near 77 GHz is maintained without the threat of preemption by higher priority services; restrict amateur and amateur-satellite operations in the 76-77 GHz frequency band to ensure against potential interference to vehicle radar systems that we expect will operate in this band; adopt a spectrum etiquette for unlicensed devices operating in the 59-64 GHz frequency band to provide a spectrum etiquette that maximizes the number of users and minimizes the potential for interference in the 59-64 GHz band; and adopt spurious emission limits for unlicensed equipment operating in the 76-77 GHz frequency band to provide protection to radio astronomy operations in the 217-231 GHz band.","action":"Final rule.","agencies":[{"raw_name":"FEDERAL COMMUNICATIONS COMMISSION","name":"Federal Communications Commission","id":161,"url":"https://www.federalregister.gov/agencies/federal-communications-commission","json_url":"https://www.federalregister.gov/api/v1/agencies/161","parent_id":null,"slug":"federal-communications-commission"}],"body_html_url":"https://www.federalregister.gov/documents/full_text/html/1998/08/07/98-20361.html","cfr_references":[{"chapter":null,"citation_url":null,"part":2,"title":47},{"chapter":null,"citation_url":null,"part":15,"title":47},{"chapter":null,"citation_url":null,"part":97,"title":47}],"citation":"63 FR 42276","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"This rule is effective September 8, 1998, except the addition of Sec. 2.1033(b)(12) which is effective October 5, 1998.","disposition_notes":null,"docket_ids":["ET Docket No. 94-124","FCC 98-150"],"dockets":[],"document_number":"98-20361","effective_on":"1998-09-08","end_page":42281,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1998/08/07/98-20361/use-of-radio-frequencies-above-40-ghz-for-new-radio-applications","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/98-20361?publication_date=1998-08-07","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1998-08-07/98-20361/mods.xml","not_received_for_publication":null,"page_length":6,"page_views":{"count":428,"last_updated":"2026-06-25 14:15:04 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1998-08-07/pdf/98-20361.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1998-08-07","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1998/08/07/98-20361.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T08:14:49Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":42276,"subtype":null,"title":"Use of Radio Frequencies Above 40 GHz for New Radio Applications","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":63}
