{"abstract":"In this document, the Federal Communications Commission (Commission) amends its rules to permit vehicular radars and certain non-vehicular fixed and mobile radars used at airports to operate in the entire 76-81 GHz band on an interference-protected basis. Access to the entire 76-81 GHz band is intended to provide sufficient spectrum bandwidth to enable the deployment of wideband high-precision short- range vehicular radar (SRR) applications, such as blind spot detectors, that can enhance the safety of drivers and other road users, while continuing to allow the deployment of proven long-range vehicular radar (LRR) applications, such as adaptive cruise control. The amended rules also permit the deployment in airport air operations areas of fixed and mobile radars that detect foreign object debris (FOD) on runways, which could harm aircraft on take-off and landing, and aircraft-mounted radars that can help aircraft avoid colliding with equipment, buildings, and other aircraft while moving on airport grounds. In addition, the amended rules allow for the continued shared use of the 76-81 GHz band by other incumbent users, including amateur radio operators and the scientific research community.","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/2017/09/20/2017-18463.html","cfr_references":[{"chapter":null,"citation_url":null,"part":1,"title":47},{"chapter":null,"citation_url":null,"part":2,"title":47},{"chapter":null,"citation_url":null,"part":15,"title":47},{"chapter":null,"citation_url":null,"part":90,"title":47},{"chapter":null,"citation_url":null,"part":95,"title":47},{"chapter":null,"citation_url":null,"part":97,"title":47}],"citation":"82 FR 43865","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":["https://www.federalregister.gov/api/v1/documents/C1-2017-18463"],"dates":"Effective date: Effective October 20, 2017, except for Sec. 15.37(l), which is effective September 20, 2018.","disposition_notes":null,"docket_ids":["ET Docket No. 15-26","FCC 17-94"],"dockets":[],"document_number":"2017-18463","effective_on":"2017-10-20","end_page":43872,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":"https://www.federalregister.gov/documents/full_text/xml/2017/09/20/2017-18463.xml","html_url":"https://www.federalregister.gov/documents/2017/09/20/2017-18463/permitting-radar-services-in-the-76-81-ghz-band","images":{"ER20SE17.002":{"large":"https://img.federalregister.gov/ER20SE17.002/ER20SE17.002_large.png","original_size":"https://img.federalregister.gov/ER20SE17.002/ER20SE17.002_original_size.png"}},"images_metadata":{"ER20SE17.002":{"large":{"identifier":"ER20SE17.002","content_type":"image/png","size":58663,"width":823,"sha":"9597a4716b696a198f81a72c67611520","url":"https://img.federalregister.gov/ER20SE17.002/ER20SE17.002_large.png","height":1140},"original_size":{"identifier":"ER20SE17.002","content_type":"image/png","size":86194,"width":3851,"sha":"3f6d8dfdbd028e77b7dac7984335000b","url":"https://img.federalregister.gov/ER20SE17.002/ER20SE17.002_original_size.png","height":5333}}},"json_url":"https://www.federalregister.gov/api/v1/documents/2017-18463?publication_date=2017-09-20","mods_url":"https://www.govinfo.gov/metadata/granule/FR-2017-09-20/2017-18463/mods.xml","not_received_for_publication":null,"page_length":8,"page_views":{"count":4743,"last_updated":"2026-06-27 04:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-2017-09-20/pdf/2017-18463.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":"https://public-inspection.federalregister.gov/2017-18463.pdf?1505825124","publication_date":"2017-09-20","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/2017/09/20/2017-18463.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2017-10-10T06:00:21Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":43865,"subtype":null,"title":"Permitting Radar Services in the 76-81 GHz Band","toc_doc":"Permitting Radar Services in 7681 GHz Band","toc_subject":null,"topics":["Communications equipment","Radio","Telecommunications"],"type":"Rule","volume":82}
