{"abstract":"By this Memorandum Opinion and Order (``MO&O''), the Commission amends the rules to permit fixed, point-to-point Unlicensed National Information Infrastructure (``U-NII'') devices in the 5.725- 5.825 GHz band to operate with one watt maximum transmitter output power and directional antennas of up to 23 dBi gain. Additionally, the MO&O amends the Commission's rules to specify transmit power limits in the form of a logarithmic equation as a function of channel bandwidth for all U-NII devices in all U-NII bands. It also clarifies the rules regarding unwanted emissions and specifies these limits in terms of absolute radiated power levels. Further, this action clarifies and addresses other issues raised in the petitions for reconsideration regarding the operation of, and regulations governing, U-NII devices. The actions taken herein will add to the flexibility and capability of U-NII operations without causing an increase in harmful interference to incumbent operations sharing the same spectrum.","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/1998/07/31/98-20429.html","cfr_references":[{"chapter":null,"citation_url":null,"part":15,"title":47}],"citation":"63 FR 40831","comment_url":null,"comments_close_on":null,"correction_of":null,"corrections":[],"dates":"August 31, 1998.","disposition_notes":null,"docket_ids":["ET Docket No. 96-102, FCC 98-121"],"dockets":[],"document_number":"98-20429","effective_on":"1998-08-31","end_page":40837,"executive_order_notes":null,"executive_order_number":null,"full_text_xml_url":null,"html_url":"https://www.federalregister.gov/documents/1998/07/31/98-20429/unlicensed-nii-devices-in-the-5-ghz-frequency-range","images":{},"images_metadata":{},"json_url":"https://www.federalregister.gov/api/v1/documents/98-20429?publication_date=1998-07-31","mods_url":"https://www.govinfo.gov/metadata/granule/FR-1998-07-31/98-20429/mods.xml","not_received_for_publication":null,"page_length":7,"page_views":{"count":435,"last_updated":"2026-06-26 20:15:03 -0400"},"pdf_url":"https://www.govinfo.gov/content/pkg/FR-1998-07-31/pdf/98-20429.pdf","presidential_document_number":null,"proclamation_number":null,"public_inspection_pdf_url":null,"publication_date":"1998-07-31","raw_text_url":"https://www.federalregister.gov/documents/full_text/text/1998/07/31/98-20429.txt","regulation_id_number_info":{},"regulation_id_numbers":[],"regulations_dot_gov_info":{"checked_regulationsdotgov_at":"2011-09-21T07:57:54Z"},"regulations_dot_gov_url":null,"significant":null,"signing_date":null,"start_page":40831,"subtype":null,"title":"Unlicensed NII Devices in the 5 GHz Frequency Range","toc_doc":null,"toc_subject":null,"topics":[],"type":"Rule","volume":63}
