1 Annex 4, Section 1 – RRC06 – 06 June 2006 Annex 4 to the Geneva 2006 (RRC- 06) Agreement, Section I: Limits and methodology for determining when agreement with another administration is required Bruno Espinosa (DG5B-6 Chairman)

2 Annex 4, Section 1 – RRC06 – 06 June 2006 Introduction Principles Example Outline of the step by step methodology How to draw contours?

3 Annex 4, Section 1 – RRC06 – 06 June 2006 Introduction Annex 4, section 1 : provisions for the modifications of the Plan and coordination of stations from other terrestrial primary services. Related to Article 4 of the Agreement Proposal developed by DG 5B-6 found in Doc 115.

4 Annex 4, Section 1 – RRC06 – 06 June 2006 Principle Method and values to identify administrations potentially affected, Defines area within which relevant field strength is exceeded, Based upon coordination contours. Administrations identified on the basis of territory for broadcasting, Administrations identified on the basis of assignment for other primary services.

5 Annex 4, Section 1 – RRC06 – 06 June 2006 Example Addition of a broadcasting assignment at 802 MHz in country A. Impact on neighbouring administrations B, C, D, E and F. Broadcasting in B, C, D, E and F. OS1 in D and F OS2 in B and E OS3 in E No OS in C

6 Annex 4, Section 1 – RRC06 – 06 June 2006 Example

7 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 1 Step 1 – Establishment of km contour In order to identify any potentially affected service all countries whose boundaries lie inside or are intersected by the km contour are taken into consideration.

8 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 1 Result of step 1: B, C, D and E are taken into consideration.

9 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 2 Step 2 – Selection of administrations whose broadcasting services are potentially affected A contour is developed based, for each frequency range, on the trigger coordination value corresponding to the broadcasting service to be protected specified in Table A1.1 and following the procedure developed in Section 3.

10 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 2 Result of step 2: contour intersecting or enclosing administrations whose broadcasting is potentially affected.

11 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 3 Step 3 – Selection of other services assignments located in the km contour In this step, assignments to other primary services are selected, based on the following criteria: –assignment belongs to an administration within the km contour; –assignment is contained in the List of assignments to other primary terrestrial services given in Annex 6 to this Agreement or for which the procedure of Article 4 of this Agreement has already been initiated.

12 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 3 Result of Step 3: OS2 in B, OS1-1 and OS1-2 in D, OS2 in E The corresponding trigger values have to be extracted from the Tables of trigger values in Appendix 1 to Annex 4.

13 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 4 Step 4 – Construction of coordination contours For each unique trigger value in the above list, a coordination contour is developed. In this way, there will be always one coordination contour for the protection of the broadcasting service identified in Step 2 and for each frequency range, possibly several coordination contours for every type of other service selected in Step 3.

14 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 4 Assignments included in their corresponding contours: OS1-1 in D, OS2 in B.

15 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 5 The administrations, with whom coordination is required, are identified by the coordination contours intersecting with or enclosing: –the national boundaries of those administrations identified in Step 2 in relation to broadcasting; –the locations of receiving stations/service areas of other primary services identified in Step 3.

16 Annex 4, Section 1 – RRC06 – 06 June 2006 Step 5 Administrations B and C identified for protection of broadcasting. Assignment OS1-1 in D and OS2 in B identified for protection of OPS. Coordination is required with B (Broadcasting and OS2), C (broadcasting) and D (OS1-1)

17 Annex 4, Section 1 – RRC06 – 06 June 2006 How to draw the contours ? Details in section 3 of Doc 115. Depends upon the coordination scenarios identified in section 4 of Doc 115. Point of reference from which radials are drawn with 1° step. For each scenario, section 4 describes how the outgoing interference field strength is calculated.

18 Annex 4, Section 1 – RRC06 – 06 June 2006 Questions??
