in Region 1,
    48.2–48.54 GHz   (space-to-Earth) in Region 1,
    49.44–50.2 GHz   (space-to-Earth) in Region 1,
and
    27.5–27.82 GHz   (Earth-to-space) in Region 1,
    28.35–28.45 GHz   (Earth-to-space) in Region 2,
    28.45–28.94 GHz   (Earth-to-space) in all Regions,
    28.94–29.1 GHz   (Earth-to-space) in Regions 2 and 3,
    29.25–29.46 GHz   (Earth-to-space) in Region 2,
    29.46–30 GHz   (Earth-to-space) in all Regions,
    48.2–50.2 GHz   (Earth-to-space) in Region 2.

     This identification does not preclude the use of these frequency bands by other fixed–satellite service applications or by other services to which these frequency bands are allocated on a co-primary basis and does not establish priority in these Radio Regulations among users of the frequency bands. Administrations should take this into account when considering regulatory provisions in relation to these frequency bands. See Resolution 143 (Rev.WRC-19).     (WRC-19)

    517 In Region 2, use of the fixed–satellite (space-to-Earth) service in the band 17.7–17.8 GHz shall not cause harmful interference to nor claim protection from assignments in the broadcasting–satellite service operating in conformity with the Radio Regulations.     (WRC-07)

    517A The operation of earth stations in motion communicating with geostationary fixed–satellite service space stations within the frequency bands 17.7–19.7 GHz (space-to-Earth) and 27.5–29.5 GHz (Earth-to-space) shall be subject to the application of Resolution 169 (WRC-19).      (WRC-19)

    519 Additional allocation:  the bands 18–18.3 GHz in Region 2 and 18.1–18.4 GHz in Regions 1 and 3 are also allocated to the meteorological–satellite service (space-to-Earth) on a primary basis. Their use is limited to geostationary satellites.     (WRC-07)

    520 The use of the band 18.1–18.4 GHz by the fixed–satellite service (Earth-to-space) is limited to feeder links of geostationary-satellite systems in the broadcasting–satellite service.     (WRC-2000)

    521 Alternative allocation:  in the United Arab Emirates and Greece, the frequency band 18.1–18.4 GHz is allocated to the fixed, fixed–satellite (space-to-Earth) and mobile services on a primary basis (see No. 33). The provisions of No. 519 also apply.     (WRC-15)

    522A The emissions of the fixed service and the fixed–satellite service in the band 18.6–18.8 GHz are limited to the values given in Nos. 21.5A and 21.16.2, respectively.     (WRC-2000)

    522B The use of the band 18.6–18.8 GHz by the fixed–satellite service is limited to geostationary systems and systems with an orbit of apogee greater than 20 000 km.     (WRC-2000)

    522C In the band 18.6–18.8 GHz, in Algeria, Saudi Arabia, Bahrain, Egypt, the United Arab Emirates, Jordan, Lebanon, Libyan Arab Jamahiriya, Morocco, Oman, Qatar, the Syrian Arab Republic, Tunisia and Yemen, fixed-service systems in operation at the date of entry into force of the Final Acts of WRC-2000 are not subject to the limits of No. 21.5A.     (WRC-2000)

    523A The use of the bands 18.8–19.3 GHz (space-to-Earth) and 28.6–29.1 GHz (Earth-to-space) by geostationary and non-geostationary fixed–satellite service networks is subject to the application of the
