6Ghz – Rules of Operation in the Unlicensed Spectrum

The 6 GHz band (5.925 – 7.125 GHz) is host to incumbent services operating on a primary basis. These services include fixed point-to-point, fixed satellite service (FSS), broadcast auxiliary service (BAC), and cable television relay service (CARS) as shown below:
