Korea, Sri Lanka, Thailand and Viet Nam. The use of this frequency band by the fixed service is intended for the implementation of fixed wireless access systems and shall comply with Recommendation ITU‑R F.1613-0. In addition, the fixed service shall not claim protection from the radiodetermination, Earth exploration–satellite (active) and space research (active) services, but the provisions of No. 43A do not apply to the fixed service with respect to the Earth exploration–satellite (active) and space research (active) services. After implementation of fixed wireless access systems in the fixed service with protection for the existing radiodetermination systems, no more stringent constraints should be imposed on the fixed wireless access systems by future radiodetermination implementations.     (WRC-15)

    447F In the frequency band 5 250–5 350 MHz, stations in the mobile service shall not claim protection from the radiolocation service, the Earth exploration–satellite service (active) and the space research service (active). The radiolocation service, the Earth exploration–satellite service (active) and the space research service (active) shall not impose more stringent conditions upon the mobile service than those stipulated in Resolution 229 (Rev.WRC-19).     (WRC-19)

    448 Additional allocation:  in Kyrgyzstan, Romania and Turkmenistan, the frequency band 5 250–5 350 MHz is also allocated to the radionavigation service on a primary basis.     (WRC-19)

    448A The Earth exploration–satellite (active) and space research (active) services in the frequency band 5 250–5 350 MHz shall not claim protection from the radiolocation service. No. 43A does not apply.     (WRC-03)

    448B The Earth exploration–satellite service (active) operating in the band 5 350–5 570 MHz and space research service (active) operating in the band 5 460–5 570 MHz shall not cause harmful interference to the aeronautical radionavigation service in the band 5 350–5 460 MHz, the radionavigation service in the band 5 460–5 470 MHz and the maritime radionavigation service in the band 5 470–5 570 MHz.     (WRC-03)

    448C The space research service (active) operating in the band 5 350–5 460 MHz shall not cause harmful interference to nor claim protection from other services to which this band is allocated.     (WRC-03)

    448D In the frequency band 5 350–5 470 MHz, stations in the radiolocation service shall not cause harmful interference to, nor claim protection from, radar systems in the aeronautical radionavigation service operating in accordance with No. 449.     (WRC-03)

    449 The use of the band 5 350–5 470 MHz by the aeronautical radionavigation service is limited to airborne radars and associated airborne beacons.

    450 Additional allocation:  in Austria, Azerbaijan, Iran (Islamic Republic of), Kyrgyzstan, Romania, Turkmenistan and Ukraine, the band 5 470–5 650 MHz is also allocated to the aeronautical radionavigation service on a primary basis.     (WRC-12)

    450A In the frequency band 5 470–5 725 MHz, stations in the mobile service shall
