MHz (centre frequency 433.92 MHz) is designated for industrial, scientific and medical (ISM) applications. Radiocommunication services of these countries operating within this frequency band must accept harmful interference which may be caused by these applications. ISM equipment operating in this frequency band is subject to the provisions of No. 15.13.     (WRC-19)

    281 Additional allocation:  in the French Overseas Departments and Communities in Region 2 and India, the band 433.75–434.25 MHz is also allocated to the space operation service (Earth-to-space) on a primary basis. In France and in Brazil, the band is allocated to the same service on a secondary basis.

    282 In the bands 435–438 MHz, 1 260–1 270 MHz, 2 400–2 450 MHz, 3 400–3 410 MHz (in Regions 2 and 3 only) and 5 650–5 670 MHz, the amateur–satellite service may operate subject to not causing harmful interference to other services operating in accordance with the Table (see No. 43). Administrations authorising such use shall ensure that any harmful interference caused by emissions from a station in the amateur–satellite service is immediately eliminated in accordance with the provisions of No. 25.11. The use of the bands 1 260–1 270 MHz and 5 650–5 670 MHz by the amateur–satellite service is limited to the Earth-to-space direction.

    283 Additional allocation:  in Austria, the band 438–440 MHz is also allocated to the fixed and mobile, except aeronautical mobile, services on a primary basis.

    284 Additional allocation:  in Canada, the band 440–450 MHz is also allocated to the amateur service on a secondary basis.

    285 Different category of service:  in Canada, the allocation of the band 440–450 MHz to the radiolocation service is on a primary basis (see No. 33).

    286 The band 449.75–450.25 MHz may be used for the space operation service (Earth-to-space) and the space research service (Earth-to-space), subject to agreement obtained under No. 9.21.

    286A The use of the bands 454–456 MHz and 459–460 MHz by the mobile–satellite service is subject to coordination under No. 9.11A.     (WRC-97)

    286AA The frequency band 450–470 MHz is identified for use by administrations wishing to implement International Mobile Telecommunications (IMT) — see Resolution 224 (Rev.WRC-19). This identification does not preclude the use of this frequency band by any application of the services to which it is allocated and does not establish priority in the Radio Regulations.     (WRC-19)

    286B The use of the band 454–455 MHz in the countries listed in 286D, 455–456 MHz and 459–460 MHz in Region 2, and 454–456 MHz and 459–460 MHz in the countries listed in 286E, by stations in the mobile–satellite service, 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.
