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 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 it is allocated and does not establish priority in the Radio Regulations. Resolution 242 (WRC-19) applies.     (WRC-19)

    533 The inter–satellite service shall not claim protection from harmful interference from airport surface detection equipment stations of the radionavigation service.

    534A The allocation to the fixed service in the frequency band 25.25–27.5 GHz is identified in Region 2 for use by high-altitude platform stations (HAPS) in accordance with the provisions of Resolution 166 (WRC-19). Such use of the fixed-service allocation by HAPS shall be limited to the ground-to-HAPS direction in the frequency band 25.25–27.0 GHz and to the HAPS-to-ground direction in the frequency band 27.0–27.5 GHz. Furthermore, the use of the frequency band 25.5–27.0 GHz by HAPS shall be limited to gateway links. This identification does not preclude the use of this frequency band by other fixed-service applications or by other services to which this band is allocated on a co-primary basis, and does not establish priority in the Radio Regulations.     (WRC‑19)

    535 In the band 24.75–25.25 GHz, feeder links to stations of the broadcasting–satellite service shall have priority over other uses in the fixed–satellite service (Earth-to-space). Such other uses shall protect and shall not claim protection from existing and future operating feeder-link networks to such broadcasting satellite stations.

    535A The use of the band 29.1–29.5 GHz (Earth-to-space) by the fixed–satellite service is limited to geostationary-satellite systems and feeder links to non-geostationary-satellite systems in the mobile–satellite service. Such use is subject to the application of the provisions of No. 9.11A, but not subject to the provisions of No. 22.2, except as indicated in Nos. 523C and 523E where such use is not subject to the provisions of No. 9.11A and shall continue to be subject to Articles 9 (except No. 9.11A) and 11 procedures, and to the provisions of No. 22.2.     (WRC-97)

    536 Use of the 25.25–27.5 GHz band by the inter–satellite service is limited to space research and Earth exploration–satellite applications, and also transmissions of data originating from industrial and medical activities in space.

    536A Administrations operating earth stations in the Earth exploration–satellite service or the space research service shall not claim protection from stations in the fixed and mobile services operated by other administrations. In addition, earth stations in the Earth exploration–satellite service or in the space research
