the Syrian Arab Republic, the Dem. Rep. of the Congo, Rwanda, Sao Tome and Principe, Senegal, Seychelles, Sierra Leone, Singapore, Slovenia, Somalia, Sudan, South Sudan, South Africa, Sweden, Tanzania, Chad, Togo, Tunisia, Zambia and Zimbabwe, the frequency band 47.2–48.2 GHz is identified for use by administrations wishing to implement 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 any priority in the Radio Regulations. Resolution 243 (WRC-19) applies.     (WRC-19)

    554 In the bands 43.5–47 GHz, 66–71 GHz, 95–100 GHz, 123–130 GHz, 191.8–200 GHz and 252–265 GHz, satellite links connecting land stations at specified fixed points are also authorised when used in conjunction with the mobile–satellite service or the radionavigation–satellite service.     (WRC-2000)

    554A The use of the bands 47.5–47.9 GHz, 48.2–48.54 GHz and 49.44–50.2 GHz by the fixed–satellite service (space-to-Earth) is limited to geostationary satellites.     (WRC-03)

    555 Additional allocation:  the band 48.94–49.04 GHz is also allocated to the radio astronomy service on a primary basis.     (WRC-2000)

    555B The power flux-density in the band 48.94–49.04 GHz produced by any geostationary space station in the fixed–satellite service (space-to-Earth) operating in the bands 48.2–48.54 GHz and 49.44–50.2 GHz shall not exceed −151.8 dB(W/m2) in any 500 kHz band at the site of any radio astronomy. station.     (WRC-03)

    555C The use of the frequency band 51.4–52.4 GHz by the fixed-satellite service (Earth-to-space) is limited to geostationary-satellite networks. The earth stations shall be limited to gateway earth stations with a minimum antenna diameters of 2.4 metres.     (WRC-19)

    556 In the bands 51.4–54.25 GHz, 58.2–59 GHz and 64–65 GHz, radio astronomy observations may be carried out under national arrangements.     (WRC-2000)

    556A Use of the bands 54.25–56.9 GHz, 57–58.2 GHz and 59–59.3 GHz by the inter–satellite service is limited to satellites in the geostationary satellite orbit. The single entry power flux-density at all altitudes from 0 km to 1 000 km above the Earth's surface produced by a station in the inter–satellite service, for all conditions and for all methods of modulation, shall not exceed −147 dB(W/(m2·100 MHz)) for all angles of arrival.     (WRC-97)

    556B Additional allocation:  in Japan, the band 54.25–55.78 GHz is also allocated to the mobile service on a primary basis for low-density use.     (WRC-97)

    557 Additional allocation:  in Japan, the band 55.78–58.2 GHz is also allocated to the radiolocation service on a primary basis.     (WRC-97)

    557A In the band 55.78–56.26 GHz, in order to protect stations in the Earth exploration–satellite service (passive), the maximum power density delivered by a transmitter to the antenna of a fixed service station is limited to −26 dB(W/MHz).     (WRC-2000)

    558 In the bands 55.78–58.2 GHz, 59–64 GHz, 66–71
