Plan & List Beams WRC-2000 PLAN WRC-2000 developed a new Plan that included: • 10 channels in Region 1 and 12 channels in Region 3; • new national beams/assignments for East Timor and the Seychelles; • 5 extended-coverage national beams for 15 administrations; • 30 "composite" beams; • new protection ratios and other technical parameters; • orbital position preferences for 63 administrations; and • 20 other national preferences. REGIONS 1 AND 3 LISTS Regions 1 and 3 Lists of Additional Uses: • Downlink List - 12 GHz List (currently 32 networks/3329 assignments) • Feeder-link List - 14 GHz List (currently 1 network/6 assignments) - 17 GHz List (currently 34 networks/2064 assignments) ELEMENTS OF LISTS • Created at WRC-2000. • Separated from the Plans and annexed to the Master Register (MIFR). • Lists are evolving and will be updated and published periodically by the BR. • Assignments in the Lists must be compatible with the Plans and other services. ELEMENTS OF LISTS (cont’d) • • • • • Digital modulation only Data elements submitted using Appendix 4 Non-monopolisation provisions 15 year time limit Provisions for use of assignments on a noninterference basis in case of disagreements • Provision to accommodate assignments for new ITU Member States COMPATIBILITY BETWEEN PLAN AND LIST ASSIGNMENTS • Plan assignments – Regions 1 & 3 Plan based on EPM – Region 2 Plan based on OEPM • List assignments – Regions 1 & 3 List based on EPM and also PFD for the downlink. Compatibility Criteria for Regions 1 & 3 Plan Assignments Equivalent Protection Margin (EPM) is used as compatibility criteria for the Regions 1 & 3 Plans as follows: 3 ( M i / 10) EPM 10 log 10 i 1 C Mi = protection margin = I iaggr PRi (dB) i = interference type (1=co-channel, 2 & 3 = upper & lower first adjacent channels); PRi = protection ratio for a given interference type i. Compatibility Criteria for Region 2 Plan Assignments Overall Equivalent Protection Margin (OEPM) is used as compatibility criteria for the Region 2 Plan as follows: 5 ( M i / 10) OEPM 10 log 10 i 1 Mi = protection margin = C I iaggr PRi (dB) i = interference type (1=co-channel, 2&3=upper & lower first adjacent channels, 4&5= upper & lower second adjacent channels); PRi = protection ratio for a given interference type i. Compatibility Criteria for Regions 1 & 3 List Assignments • Based on both EPM and PFD criteria. – EPM criteria as per the Regions 1 & 3 Plan – PFD criteria also used to identify affected assignments as per Annex 1 of Ap.30 MAIN REGULATORY ASPECTS • BSS Downlink/ Feeder-link - Modification/Addition/Coordination (Article 4) - Notification/Implementation (Article 5) • Terrestrial - Coordination/Notification (Article 6) • FSS - Coordination/Notification (Article 7) • Space Operation/TT&C in the Guardbands - Coordination/Notification (Article 2A) ARTICLE 5 EXAMINATION • conformity with the Convention, Table of Allocations, other provisions • conformity with the Plan and List (except reduced e.i.r.p, reduced coverage etc.) • protection of other services in specific cases • Notified technical characteristics have to be the same as those in the Plans or Lists except those allowed in provision 5.2.1 d) ARTICLE 4 EXAMINATION (Appendix 30 Regions 1 & 3) • Protection of the Regions 1 & 3 Plan and List - SPS/MSPACE: EPM & PFD calculations • Protection of Region 2 Plan - GIBC(PXT)/GIMS: PFD • Protection of Terrestrial Services - GIBC/GIMS: PFD • Protection of Region 2 and Region 3 FSS - GIBC(PXT)/GIMS: PFD ARTICLE 4 EXAMINATION (Appendix 30A Regions 1&3) • Protection of Regions 1&3 Plan and Lists - SPS/MSPACE: EPM calculation • Protection of the Region 2 Plan - GIBC(Appendix 8): delta T/T • Protection of Region 2 FSS receiving feederlink space stations (17.8-18.1 GHz) - GIBC(Appendix 8): delta T/T Processing of Article 4 Submissions (1) • Bureau is currently processing all as yet unpublished submissions received under Article 4 using the revised Appendices 30 and 30A in accordance with Resolution 546 (WRC-03). • Special Sections, that contain the filed satellite network characteristics and potentially affected administrations, are being published in BR IFICs. • Administrations should examine each BR IFIC to see if it’s assignments are affected and respond within 4 months. Processing of Article 4 Submissions (2) • Affected administrations that do not comment within the 4 month period are deemed to have agreed. • After the 4 month period has expired, the BR prepares a list of coordination agreements required and publishes this in a Part D Special Section. • Results of the Bureau’s MSPACEg calculations are also placed on the BR IFIC. • Workshop session will explain this in more detail. Plan and List data • All Plan and List assignment data can be found on the BR IFIC & the ITU website at: http://www.itu.int/ITU-R/space/plans/index.html • Contained in the SPS database (SNS Version 5 format). • Contains the technical characteristics and reference situation for all Plan, List and pending Article 4 assignments. • The SPS database is evolving and is updated regularly. Post WRC-03 Activities • Update of the Reference Situation (EPM/OEPM) for Plan & List assignments; • Implementation of Resolution 548 (WRC-03); • Implementation of the grouping concept in Regions 1 & 3; • Processing of Article 2A, 4 & 5 notices; • Implementation of Resolution 547.
