RES148 – 233 – MOD RESOLUTION 148 (REV.WRC-15) Satellite systems formerly listed in Part B of the Plan of Appendix 30B (WARC Orb-88) The World Radiocommunication Conference (Geneva, 2015), considering a) that WARC Orb-88 adopted a Plan for the fixed-satellite service in the frequency bands 4 500-4 800 MHz, 6 725-7 025 MHz, 10.70-10.95 GHz, 11.20-11.45 GHz and 12.75-13.25 GHz contained in Appendix 30B (WARC Orb-88); b) that, when the Plan was adopted, some satellite systems in the same frequency bands were under coordination or had been recorded in the Master International Frequency Register (MIFR), or had information relating to advance publication that was received by the Radiocommunication Bureau before 8 August 1985, and which in all cases were listed in Part B of the Plan at WARC Orb-88; c) that in the original provisions of Appendix 30B (WARC Orb-88), the satellite systems mentioned in considering b) above were referred to as “existing systems”; d) that satellite systems identified in considering b) have either been included in the List of Appendix 30B or cancelled, and thus Part B of the Plan is empty; e) that, therefore, WRC-07 suppressed Part B of the Plan in Appendix 30B, recognizing a) that § 9.2 of Appendix 30B (WARC Orb-88) indicates that “The existing systems listed in Part B of the Plan may continue in operation for a maximum period of 20 years from the date of entry into force of this Appendix”, and consequently the period of operation of satellite systems in Part B of the Plan expires after 16 March 2010; b) that some administrations expressed their wish to continue operation of these systems after the deadline mentioned in recognizing a); c) that satellite systems referred to in considering b) are compatible with satellite networks in Appendix 30B, resolves that an administration wishing to further extend the notified period of validity of assignments to “existing system(s)” as referred to in considering c) shall inform the Bureau accordingly more than three years before the expiry of the notified period of validity and, if the characteristics of that assignment remain unchanged, the Bureau shall amend, as requested, the notified period of validity and publish that information in a special section of the Bureau’s International Frequency Information Circular (BR IFIC),
