the frequency band 7 190–7 250 MHz shall not claim protection from existing and future stations in the fixed and mobile services, and No. 43A does not apply. No. 17 applies. Additionally, to ensure protection of the existing and future deployment of fixed and mobile services, the location of earth stations supporting spacecraft in the Earth exploration–satellite service in non-geostationary orbits or geostationary orbit shall maintain a separation distance of at least 10 km and 50 km, respectively, from the respective border(s) of neighbouring countries, unless a shorter distance is otherwise agreed between the corresponding administrations.     (WRC-15)

    460B Space stations on the geostationary orbit operating in the Earth exploration–satellite service (Earth-to-space) in the frequency band 7 190–7 235 MHz shall not claim protection from existing and future stations of the space research service, and No. 43A does not apply.     (WRC-15)

    461 Additional allocation:  the bands 7 250–7 375 MHz (space-to-Earth) and 7 900–8 025 MHz (Earth-to-space) are also allocated to the mobile–satellite service on a primary basis, subject to agreement obtained under No. 9.21.

    461A The use of the band 7 450–7 550 MHz by the meteorological–satellite service (space-to-Earth) is limited to geostationary-satellite systems. Non-geostationary meteorological–satellite systems in this band notified before 30 November 1997 may continue to operate on a primary basis until the end of their lifetime.     (WRC-97)

    461AA The use of the frequency band 7 375–7 750 MHz by the maritime mobile–satellite service is limited to geostationary-satellite networks.     (WRC-15)

    461AB In the frequency band 7 375–7 750 MHz, earth stations in the maritime mobile–satellite service shall not claim protection from, nor constrain the use and development of, stations in the fixed and mobile, except aeronautical mobile, services. No. 43A does not apply.     (WRC-15)

    461B The use of the band 7 750–7 900 MHz by the meteorological–satellite service (space-to-Earth) is limited to non-geostationary-satellite systems.     (WRC-12)

    462A In Regions 1 and 3 (except for Japan), in the band 8 025–8 400 MHz, the Earth exploration–satellite service using geostationary-satellites shall not produce a power flux-density in excess of the following values for angles of arrival (), without the consent of the affected administration:
     −135 dB(W/m2) in a 1 MHz band    for 0 ≤  < 5
     −135 + 0.5 ( − 5) dB(W/m2) in a 1 MHz band  for 5 ≤  < 25
     −125 dB(W/m2) in a 1 MHz band    for 25 ≤  ≤ 90

    463 Aircraft stations are not permitted to transmit in the band 8 025–8 400 MHz.     (WRC-97)

    465 In the space research service, the use of the band 8 400–8 450 MHz is limited to deep space.

    466 Different category of service:  in Singapore and Sri Lanka, the allocation of the band 8 400–8
