RES903 – 434 – MOD RESOLUTION 903 (REV.WRC-15) Transitional measures for certain broadcasting-satellite/fixed-satellite service systems in the frequency band 2 500-2 690 MHz The World Radiocommunication Conference (Geneva, 2015), considering a) that WRC-07 revised the limits of power flux-density from space stations in Article 21, Table 21-4 for the frequency band 2 500-2 690 MHz; b) that use of the frequency bands 2 500-2 690 MHz in Region 2 and 2 500-2 535 MHz and 2 655-2 690 MHz in Region 3 by the fixed-satellite service (FSS) is limited to national and regional systems, subject to agreement obtained under No. 9.21 (see No. 5.415 and No. 5.2.1); c) that in the frequency band 2 520-2 670 MHz, the broadcasting-satellite service (BSS) is limited to national and regional systems, subject to agreement obtained under No. 9.21 (see No. 5.416 and No. 5.2.1); d) that, in No. 5.384A, the frequency band 2 500-2 690 MHz is identified as one of the frequency bands for use by administrations wishing to implement International Mobile Telecommunications (IMT) in accordance with Resolution 223 (Rev.WRC-15); e) that, due to the specific national and regional allocation status applied to the space services mentioned above, and the identification for use by administrations wishing to implement IMT, it is advantageous to apply the revised Article 21, Table 21-4 limits in the frequency band 2 500-2 690 MHz at an early date; f) that agenda item 1.9 of WRC-07 mentioned a requirement to not place undue constraints on the services to which the frequency band is allocated, resolves 1 that in the frequency band 2 500-2 690 MHz space stations of satellite networks listed in Annex 1 to this Resolution shall not exceed the following pfd values: −152 dB(W/m2) for δ < 5° −152 + 0.75 (δ − 5) dB(W/m2) for 5° ≤ δ ≤ 25° −137 dB(W/m2) for δ > 25° in any 4 kHz band, where δ is the angle of arrival above the horizontal plane. The limits in Table 21-4 do not apply;
