Scope

Section 6 of Annex 1 to RR Appendix 30 provides power flux-density (pfd) values to determine if a proposed BSS network in one Region needs to coordinate with an FSS network in another Region, in the frequency band 11.7-12.7 GHz. The mask in that section provides the envelope of pfd values to trigger coordination with a wide range of FSS earth station antenna sizes. This Recommendation gives a table of levels equivalent to those in § 6 of Annex 1 to RR Appendix 30 for particular combinations of FSS earth station antenna size and system noise temperature, and also describes the methodology by which these levels were computed and a methodology to determine such levels for other earth station antenna sizes by interpolation.
