MHz in networks for which complete coordination information has been received by the Radiocommunication Bureau before 28 October 2019.     (WRC-19)

    374 Mobile Earth stations in the mobile–satellite service operating in the bands 1 631.5–1 634.5 MHz and 1 656.5–1 660 MHz shall not cause harmful interference to stations in the fixed service operating in the countries listed in No. 359.     (WRC-97)

    375 The use of the band 1 645.5–1 646.5 MHz by the mobile–satellite service (Earth-to-space) and for inter–satellite links is limited to distress and safety communications (see Article 31).

    376 Transmissions in the band 1 646.5–1 656.5 MHz from aircraft stations in the aeronautical mobile (R) service directly to terrestrial aeronautical stations, or between aircraft stations, are also authorized when such transmissions are used to extend or supplement the aircraft-to-satellite links.

    376A Mobile Earth stations operating in the band 1 660.0–1 660.5 MHz shall not cause harmful interference to stations in the radio astronomy service.     (WRC-97)

    379 Additional allocation:  in Bangladesh, India, Indonesia, Nigeria and Pakistan, the band 1 660.5–1 668.4 MHz is also allocated to the meteorological aids service on a secondary basis.

    379A Administrations are urged to give all practicable protection in the band 1 660.5–1 668.4 MHz for future research in radio astronomy, particularly by eliminating air-to-ground transmissions in the meteorological aids service in the band 1 664.4–1 668.4 MHz as soon as practicable.

    379B The use of the band 1 668–1 675 MHz by the mobile–satellite service is subject to coordination under No. 9.11A. In the band 1 668–1 668.4 MHz, Resolution 904 (WRC-07) shall apply.     (WRC-07)

    379C In order to protect the radio astronomy service in the band 1 668–1 670 MHz, the aggregate power flux-density values produced by mobile Earth stations in a network of the mobile–satellite service operating in this band shall not exceed −181 dB(W/m2) in 10 MHz and −194 dB(W/m2) in any 20 kHz at any radio astronomy station recorded in the Master International Frequency Register, for more than 2% of integration periods of 2 000 s.     (WRC-03)

    379D For sharing of the band 1 668.4–1 675 MHz between the mobile–satellite service and the fixed and mobile services, Resolution 744 (Rev.WRC-07) shall apply.     (WRC-07)

    379E In the band 1 668.4–1 675 MHz, stations in the mobile–satellite service shall not cause harmful interference to stations in the meteorological aids service in China, Iran (Islamic Republic of), Japan and Uzbekistan. In the band 1 668.4–1 675 MHz, administrations are urged not to implement new systems in the meteorological aids service and are encouraged to migrate existing meteorological aids service operations to other bands as soon as practicable.     (WRC-03)

    380A In the band 1 670–1 675 MHz, stations in the mobile–satellite service shall
