to protect stations in the Earth exploration–satellite service (passive), the maximum power density delivered by a transmitter to the antenna of a fixed service station is limited to −26 dB(W/MHz).     (WRC-2000)

    558 In the bands 55.78–58.2 GHz, 59–64 GHz, 66–71 GHz, 122.25–123 GHz, 130–134 GHz, 167–174.8 GHz and 191.8–200 GHz, stations in the aeronautical mobile service may be operated subject to not causing harmful interference to the inter–satellite service (see No. 43).     (WRC-2000)

    558A Use of the band 56.9–57 GHz by inter–satellite systems is limited to links between satellites in geostationary-satellite orbit and to transmissions from non-geostationary satellites in high-Earth orbit to those in low-Earth orbit. For links between satellites in the geostationary-satellite orbit, the single entry power flux-density at all altitudes from 0 km to 1 000 km above the Earth's surface, for all conditions and for all methods of modulation, shall not exceed −147 dB(W/(m2·100 MHz)) for all angles of arrival.     (WRC-97)

    559 In the band 59–64 GHz, airborne radars in the radiolocation service may be operated subject to not causing harmful interference to the inter–satellite service (see No. 43).     (WRC-2000)

    559AA The frequency band 66–71 GHz is identified for use by administrations wishing to implement the terrestrial component of International Mobile Telecommunications (IMT). This identification does not preclude the use of this frequency band by any application of the services to which this frequency band is allocated and does not establish priority in the Radio Regulations. Resolution 241 (WRC-19) applies.     (WRC-19)

    559B The use of the frequency band 77.5–78 GHz by the radiolocation service shall be limited to short-range radar for ground-based applications, including automotive radar. The technical characteristics of those radars are provided in the most recent version of Recommendation ITU-R M.2057. The provisions of No. 4.10 do not apply.     (WRC-15)

    560 In the band 78–79 GHz radars located on space stations may be operated on a primary basis in the Earth exploration–satellite service and in the space research service.

    561 In the band 74–76 GHz, stations in the fixed, mobile and broadcasting services shall not cause harmful interference to stations of the fixed–satellite service or stations of the broadcasting–satellite service operating in accordance with the decisions of the appropriate frequency assignment planning conference for the broadcasting–satellite service.     (WRC-2000)

    561A The 81–81.5 GHz band is also allocated to the amateur and amateur–satellite services on a secondary basis.

    561B In Japan, use of the band 84–86 GHz, by the fixed–satellite service (Earth-to-space) is limited to feeder links in the broadcasting–satellite service using the geostationary-satellite orbit.     (WRC-2000)

    562 The use of the band 94–94.1 GHz by the Earth exploration–satellite (active) and space research (active) services is limited to spaceborne cloud radars.     (WRC-97)

    562A In the bands 94–94.1 GHz
