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 shall be in accordance with the provisions of Resolution 167 (WRC‑19).      (WRC‑19)

    544 In the band 31–31.3 GHz the power flux-density limits specified in Article 21, Table 21–4, shall apply to the space research service.

    545 Different category of service:  in Armenia, Georgia, Kyrgyzstan, Tajikistan and Turkmenistan, the allocation of the band 31–31.3 GHz to the space research service is on a primary basis (see No. 33).     (WRC-12)

    546 Different category of service:  in Saudi Arabia, Armenia, Azerbaijan, Bahrain, Belarus, Egypt, the United Arab Emirates, Spain, Estonia, the Russian Federation, Georgia, Hungary, Iran (Islamic Republic of), Israel, Jordan, Lebanon, Moldova, Mongolia, Oman, Uzbekistan, Poland, the Syrian Arab Republic, Kyrgyzstan, Romania, the United Kingdom, South Africa, Tajikistan, Turkmenistan and Turkey, the allocation of the frequency band 31.5–31.8 GHz to the fixed and mobile, except aeronautical mobile, services is on a primary basis (see No. 33).     (WRC-19)

    547 The bands 31.8–33.4 GHz, 37–40 GHz, 40.5–43.5 GHz, 51.4–52.6 GHz, 55.78–59 GHz and 64–66 GHz are available for high-density applications in the fixed service (see Resolution 75 (WRC-2000)). Administrations should take this into account when considering regulatory provisions in relation to these bands. Because of the potential deployment of high-density applications in the fixed–satellite service in the bands 39.5–40 GHz and 40.5–42 GHz (see No. 516B), administrations should further take into account potential constraints to high-density applications in the fixed service, as appropriate.     (WRC-07)

    547A Administrations should take practical measures to minimize the potential interference between stations in the fixed service and airborne stations in the radionavigation service in the 31.8–33.4 GHz band, taking into account the operational needs of the airborne radar systems.     (WRC-2000)

    547B Alternative allocation:  in the United States, the band 31.8–32 GHz is allocated to the radionavigation and space research (deep space) (space-to-Earth) services on a primary basis.     (WRC-97)

    547C Alternative allocation:  in the United States, the band 32–32.3 GHz is allocated to the radionavigation and space research (deep space) (space-to-Earth) services on a primary basis.     (WRC-03)

    547D Alternative allocation:  in the United States, the band 32.3–33 GHz is allocated to the inter–satellite and radionavigation services on a primary basis.     (WRC-97)

    547E Alternative allocation:  in the United States, the band 33–33.4 GHz is allocated to the radionavigation service on a primary basis.     (WRC-97)

    548 In designing systems for the inter–satellite service in the band 32.3–33 GHz, for the radionavigation service in the band 32–33 GHz, and for the space research service (deep space) in the band 31.8–32.3 GHz, administrations shall take all necessary measures
