Abstract: This Technical Report provides details about protection of federal operations in the 5.850–5.925 GHz (5.9 GHz) band from new operations considered by the Federal Communications Commission (FCC) as part of the agency’s comprehensive review intended to allow for the highest and best use of the band. As part of its ongoing effort to accommodate new commercial wireless services, the National Telecommunications and Information Administration (NTIA) worked with agencies that operate federal systems in the band to determine the protections needed to permit new commercial services to operate without causing impact to incumbent operations. To facilitate the FCC’s expeditious review of the record, NTIA already submitted to the FCC a letter setting forth the relevant protection requirements derived from the numerous details provided in this Technical Report.
