the fixed–satellite service (space-to-Earth) in this frequency band.     (WRC-15)

    500 Additional allocation:  in Algeria, Saudi Arabia, Bahrain, Brunei Darussalam, Cameroon, Egypt, the United Arab Emirates, Gabon, Indonesia, Iran (Islamic Republic of), Iraq, Israel, Jordan, Kuwait, Lebanon, Madagascar, Malaysia, Mali, Morocco, Mauritania, Niger, Nigeria, Oman, Qatar, the Syrian Arab Republic, Singapore, Sudan, South Sudan, Chad and Tunisia, the frequency band 13.4–14 GHz is also allocated to the fixed and mobile services on a primary basis. In Pakistan, the frequency band 13.4–13.75 GHz is also allocated to the fixed and mobile services on a primary basis.     (WRC-15)

    501 Additional allocation:  in Azerbaijan, Hungary, Japan, Kyrgyzstan, Romania and Turkmenistan, the band 13.4–14 GHz is also allocated to the radionavigation service on a primary basis.     (WRC-12)

    501A The allocation of the frequency band 13.65–13.75 GHz to the space research service on a primary basis is limited to active spaceborne sensors. Other uses of the frequency band by the space research service are on a secondary basis.     (WRC-15)

    501B In the band 13.4–13.75 GHz, the Earth exploration–satellite (active) and space research (active) services shall not cause harmful interference to, or constrain the use and development of, the radiolocation service.     (WRC-97)

    502 In the band 13.75–14 GHz, an Earth station of a geostationary fixed–satellite service network shall have a minimum antenna diameter of 1.2 m and an Earth station of a non-geostationary fixed–satellite service system shall have a minimum antenna diameter of 4.5 m. In addition, the e.i.r.p., averaged over one second, radiated by a station in the radiolocation or radionavigation services shall not exceed 59 dBW for elevation angles above 2° and 65 dBW at lower angles. Before an administration brings into use an Earth station in a geostationary-satellite network in the fixed–satellite service in this band with an antenna diameter smaller than 4.5 m, it shall ensure that the power flux-density produced by this Earth station does not exceed:
         * −115 dB(W/(m2·10 MHz)) for more than 1% of the time produced at 36 m above sea level at the low water mark, as officially recognised by the coastal State;
         * −115 dB(W/(m2·10 MHz)) for more than 1% of the time produced 3 m above ground at the border of the territory of an administration deploying or planning to deploy land mobile radars in this band, unless prior agreement has been obtained.
    For Earth stations within the fixed–satellite service having an antenna diameter greater than or equal to 4.5 m, the e.i.r.p. of any emission should be at least 68 dBW and should not exceed 85 dBW.     (WRC-03)

    503 In the band 13.75–14 GHz, geostationary space stations in the space research service for which information for advance publication has been received by the Bureau prior
