shall not produce a power flux-density in excess of −120.4 dB(W/(m2·MHz)) at 3 m above the ground of any point of the territory of any other administration in Regions 1 and 3 for more than 20% of the time. In conducting the calculations, administrations should use the most recent version of Recommendation ITU‑R P.452 (see also the most recent version of Recommendation ITU‑R BO.1898).     (WRC-15)

    530B In the band 21.4–22 GHz, in order to facilitate the development of the broadcasting–satellite service, administrations in Regions 1 and 3 are encouraged not to deploy stations in the mobile service and are encouraged to limit the deployment of stations in the fixed service to point-to-point links.     (WRC-12)

    530E The allocation to the fixed service in the frequency band 21.4–22 GHz is identified for use in Region 2 by high-altitude platform stations (HAPS). This identification does not preclude the use of this frequency band by other fixed-service applications or by other services to which it is allocated on a co-primary basis, and does not establish priority in the Radio Regulations. Such use of the fixed-service allocation by HAPS is limited to the HAPS-to-ground direction, and shall be in accordance with the provisions of Resolution 165 (WRC-19).     (WRC-19)

    531 Additional allocation:  in Japan, the band 21.4–22 GHz is also allocated to the broadcasting service on a primary basis.

    532 The use of the band 22.21–22.5 GHz by the Earth exploration–satellite (passive) and space research (passive) services shall not impose constraints upon the fixed and mobile, except aeronautical mobile, services.

    532A The location of earth stations in the space research service shall maintain a separation distance of at least 54 km from the respective border(s) of neighbouring countries to protect the existing and future deployment of fixed and mobile services unless a shorter distance is otherwise agreed between the corresponding administrations. Nos. 9.17 and 9.18 do not apply.

    532B Use of the band 24.65–25.25 GHz in Region 1 and the band 24.65–24.75 GHz in Region 3 by the fixed–satellite service (Earth-to-space) is limited to earth stations using a minimum antenna diameter of 4.5 m.     (WRC-12)

    532AA The allocation to the fixed service in the frequency band 24.25–25.25 GHz is identified for use in Region 2 by high-altitude platform stations (HAPS). This identification does not preclude the use of this frequency band by other fixed-service applications or by other services to which this frequency band is allocated on a co-primary basis, and does not establish priority in the Radio Regulations. Such use of the fixed-service allocation by HAPS is limited to the HAPS-to-ground direction and shall be in accordance with the provisions of Resolution 166 (WRC-19).     (WRC-19)

    532AB The frequency band 24.25–27.5 GHz is identified for use
