South Sudan and Tanzania, the frequency band 138–144 MHz is also allocated to the fixed service on a primary basis.     (WRC-19)

    216 Additional allocation:  in China, the band 144–146 MHz is also allocated to the aeronautical mobile (OR) service on a secondary basis.

    217 Alternative allocation:  in Afghanistan, Bangladesh, Cuba, Guyana and India, the band 146–148 MHz is allocated to the fixed and mobile services on a primary basis.

    218 Additional allocation:  the band 148–149.9 MHz is also allocated to the space operation service (Earth-to-space) on a primary basis, subject to agreement obtained under No. 9.21. The bandwidth of any individual transmission shall not exceed ±25 kHz.

    218A The frequency band 148–149.9 MHz in the space operation service (Earth-to-space) may be used by non-geostationary-satellite systems with short-duration missions. Non-geostationary-satellite systems in the space operation service used for short-duration missions in accordance with Resolution 32 (WRC-19) of the Radio Regulations are not subject to agreement under No. 9.21. At the stage of coordination, the provisions of Nos. 9.17 and 9.18 also apply. In the frequency band 148–149.9 MHz, non-geostationary–satellite systems with short-duration missions shall not cause unacceptable interference to, or claim protection from, existing primary services within this frequency band, or impose additional constraints on the space operation and mobile–satellite services. In addition, earth stations in non-geostationary-satellite systems in the space operation service with short-duration missions in the frequency band 148-149.9 MHz shall ensure that the power flux-density does not exceed −149 dB(W/(m2  4 kHz)) for more than 1% of time at the border of the territory of the following countries: Armenia, Azerbaijan, Belarus, China, Korea (Rep. of), Cuba, Russian Federation, India, Iran (Islamic Republic of), Japan, Kazakhstan, Malaysia, Uzbekistan, Kyrgyzstan, Thailand and Viet Nam. In case this power flux-density limit is exceeded, agreement under No. 9.21 is required to be obtained from countries mentioned in this footnote.     (WRC-19)

    219 The use of the frequency band 148–149.9 MHz by the mobile–satellite service is subject to coordination under No. 9.11A. The mobile–satellite service shall not constrain the development and use of the fixed, mobile and space operation services in the frequency band 148–149.9 MHz. The use of the frequency band 148-149.9 MHz by non-geostationary-satellite systems in the space operation service identified as short-duration mission is not subject to No. 9.11A.     (WRC-19)

    220 The use of the frequency bands 149.9–150.05 MHz and 399.9–400.05 MHz by the mobile–satellite service is subject to coordination under No. 9.11A.     (WRC-15)

    221 Stations of the mobile–satellite service in the frequency band 148–149.9 MHz shall not cause harmful interference to, or claim protection from, stations of the fixed or mobile services operating in accordance with the Table of Frequency Allocations in the following countries: Albania, Algeria, Germany, Saudi
