Slide 10 World Radiocommunication Seminar Geneva, November 2004 Examination of Part B submissions under § / of Article 4 of Appendices 30 and 30A (1) Technical Examinations According to § / of Article 4 of Appendices 30 and 30A, in requesting the publication of a Part B Special Section, administrations may modify certain parameters of a network previously published in a Part A Special Section in order to overcome unresolved disagreements. This requires that a new series of technical examinations be carried out by the Bureau in order to investigate whether or not an objecting administrations networks/territories are still identified as affected by the modified parameters. Moreover, checks are made to ascertain that no additional interference is imposed on an administration that has not objected or has previously agreed after an objection. The technical examinations required for the Part B submission is same as for Part A as listed the previous slides. However, the results of the examinations are compared with those of the relevant Part A examinations. Accordingly, for examination under § 4.1.1a) & b) / § 4.2.3c) of Appendix 30 and § 4.1.1a) & b) / § 4.2.2c) of Appendix 30A, the SPS_ALL database included in the BR IFIC of the networks Part A publication is used.

Slide 11 World Radiocommunication Seminar Geneva, November 2004 Examination of Part B submissions (2) Coordination requirement examination An indication of the agreements required or not based on different configurations of a network/Plan beam/Country identified as affected in the Part A / Part B technical examination are listed the following slide. In order to establish coordination requirements for an affected network/Plan beam/Country identified in the technical examination results, the following scenarios are taken into account: -whether the same network/Plan beam/Country was identified as affected in the relevant Part A Special Section; -whether the administration whose network/Plan beam/Country is identified as affected has objected to the corresponding Part A Special Section; - whether the level of the interference resulting from the Part B network characteristics is more than that resulting from the relevant Part A network characteristics. A separate coordination requirement is established for each affected administration under each paragraph of § / of Appendix 30 and § / of Appendix 30A.

Slide 12 World Radiocommunication Seminar Geneva, November 2004 Examination of Part B submissions (3) Coordination requirement examination Network/Plan Beam/Country identified in? Interference level of Part B higher than Part A? Objecting administratio n? Agreement is required ? Observation No Part A Technic al Exam Part B Technica l Exam 1X NA Since the affected network/Plan Beam/Country is no more identified in the updated Part B results, agreement is not required. 2X NA X 3XX Since the level of interference of Part B is not greater than that of the published Part A, the previous implicit agreement of the affected administrant is still valid. 4XXXX Since the objecting administration is still identified as affected, its agreement is required. 5XXXXX 6XXXX Since the level of interference of Part B is greater than that of the published Part A, the previous implicit agreement of the affected adm. is no longer valid. An explicit agreement is therefore required. 7X NA X The agreement of the affected administration whose service/network has been newly identified as affected, is required. : NOX: YESNA: Not Applicable Objecting administration: An administration identified as affected who has communicated an objection within the regulatory time limit and has not subsequently has given its agreed.

Slide 13 World Radiocommunication Seminar Geneva, November 2004 Examination of Part B submissions (4) Exercise on the sample SPS_ALL database - MSPACE a) Export the R13DN-LINK network from SPS_ALL_IFIC9999.mdb to a new database to the C:\Br_soft\SPS\R13DN-LINK_PartB.mdb database with the options Keep Findings and Ref. Situations unchecked and Keep group Ids of the source checked; b) Open the above created database in SpaceCap and delete beams 5 and 6 and odd channels of beam 3 (group id 384); c) Export back the R13DN-LINK network with the modified characteristics from the C:\Br_soft\SPS\R13DN-LINK_PartB.mdb database into the SPS_ALL_IFIC9999.mdb database with the options Replace Notice in Target and Keep group Ids of the source checked; d) Rename the SPS_ALL_IFIC9999.mdb database as SPS_ALL_R13DN-LINK_PartB.mdb; e) Copy the GIMS database D:\Exercise\SPS_GIMS_Sample.mdb to C:\Br_soft\Data; f) Run MSPACE on SPS_ALL_R13DN-LINK_PartB.mdb selecting downlink Plan/List and include the above mentioned GIMS database. Once the program finishes, select the Compressed report tab, select the option PFD and EPM, press Create Draft of Special Section, to create the report file SS_AP_30C.rtf; g) Compare the above-mentioned report with R13DN-LINK_PartA.rtf created on the Part A slide 8.
