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.

9
REGIONS 1 AND 3 LISTS

• Regions 1 and 3 Lists of additional uses
• Downlink List- 12 GHz List (currently 28
  networks/204 beams)
• Feeder-link Lists- 14 GHz List (currently 1
  network/1 beam) - 17 GHz List (currently 24
  networks/160 beams)

10
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.

11
ELEMENTS OF LISTS (contd)

• Digital modulation only
• Data elements submitted using Appendix 4
• Non-monopolisation provisions
• 15 year time limit
• Use of assignments on a non-interference basis in
  case of disagreements
• Provision to accommodate assignments for new ITU
  Member States

12
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.

13
Compatibility Criteria forRegions 1 3 Plan
Assignments

• Equivalent Protection Margin (EPM) is used as
  compatibility criteria for the Regions 1 3
  Plans as follows
• Mi protection margin
  (dB)
• i interference type (1co-channel, 2 3
  upper lower first adjacent
  channels)
• PRi protection ratio for a given interference
  type i.

14
Compatibility Criteria forRegion 2 Plan
Assignments

• Overall Equivalent Protection Margin (OEPM) is
  used as compatibility criteria for the Region 2
  Plan as follows
• Mi protection margin
  (dB)
• i interference type (1co-channel, 23upper
  lower first adjacent channels, 45 upper
  lower second adjacent channels)
• PRi protection ratio for a given interference
  type i.

15
Compatibility Criteria forRegions 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

16
MAIN REGULATORY ASPECTS

• BSS Downlink/ Feeder-link- Modification/addition
  (Article 4) - Notification/Implementation
  (Article 5)
• Terrestrial - Coordination/Notification (Article
  6)
• FSS - Coordination/Notification (Article 7)

17
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

18
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

19
ARTICLE 4 EXAMINATION (Appendix 30A Regions 13)

• Protection of Regions 13 Plan and Lists -
  SPS/MSPACE EPM calculation
• Protection of Region 2 Plan - Appendix 8
  delta T/T
• Protection of Terrestrial Services - Appendix 7
  Coordination contour
• Protection of FSS earth station - Annex 4
  Coordination contour

20
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.
• 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 its assignments are affected and respond
  within 4 months.

21
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.
• Results of the Bureaus MSPACEg calculations are
  also placed on the BR IFIC.
• Workshop session will explain this in more detail.

22
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 (SRS 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.

23
Workshop SessionThursday 14 Nov 1630-1730

• How to determine if an administration is
  identified as affected by a proposed Article 4
  satellite network in BR Publications.
• Using the SPS and other BR software applications
  to obtain the technical examination results.
