27.500–27.501 GHz and 29.999–30.000 GHz are also allocated to the fixed–satellite service (space-to-Earth) on a primary basis for the beacon transmissions intended for up-link power control. Such space-to-Earth transmissions shall not exceed an equivalent isotropically radiated power (e.i.r.p.) of +10 dBW in the direction of adjacent satellites on the geostationary-satellite orbit.     (WRC-07)

    539 The band 27.5–30 GHz may be used by the fixed–satellite service (Earth-to-space) for the provision of feeder links for the broadcasting–satellite service.

    540 Additional allocation:  the band 27.501–29.999 GHz is also allocated to the fixed–satellite service (space-to-Earth) on a secondary basis for beacon transmissions intended for up-link power control.

    541 In the band 28.5–30 GHz, the Earth exploration–satellite service is limited to the transfer of data between stations and not to the primary collection of information by means of active or passive sensors.

    541A Feeder links of non-geostationary networks in the mobile–satellite service and geostationary networks in the fixed–satellite service operating in the band 29.1–29.5 GHz (Earth-to-space) shall employ uplink adaptive power control or other methods of fade compensation, such that the Earth station transmissions shall be conducted at the power level required to meet the desired link performance while reducing the level of mutual interference between both networks. These methods shall apply to networks for which Appendix 4 coordination information is considered as having been received by the Bureau after 17 May 1996 and until they are changed by a future competent World Radiocommunication Conference. Administrations submitting Appendix 4 information for coordination before this date are encouraged to utilize these techniques to the extent practicable.     (WRC-2000)

    542 Additional allocation:  in Algeria, Saudi Arabia, Bahrain, Brunei Darussalam, Cameroon, China, Congo (Rep. of the), Egypt, the United Arab Emirates, Eritrea, Ethiopia, Guinea, India, Iran (Islamic Republic of), Iraq, Japan, Jordan, Kuwait, Lebanon, Malaysia, Mali, Morocco, Mauritania, Nepal, Oman, Pakistan, Philippines, Qatar, the Syrian Arab Republic, the Dem. People's Rep. of Korea, Somalia, Sudan, South Sudan, Sri Lanka and Chad, the band 29.5–31 GHz is also allocated to the fixed and mobile services on a secondary basis. The power limits specified in Nos. 21.3 and 21.5 shall apply.     (WRC-12)

    543 The band 29.95–30 GHz may be used for space-to-space links in the Earth exploration–satellite service for telemetry, tracking, and control purposes, on a secondary basis.

    543B The allocation to the fixed service in the frequency band 31–31.3 GHz is identified for worldwide use by high-altitude platform stations (HAPS). This identification does not preclude the use of this frequency band 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
