Procedures to Register Satellite Earth Stations at the ITU 1. Introduction The band 3 400-3 600 MHz was identified by WRC-07 for International Mobile Telecommunications (IMT) in many countries in ITU Region 1 (Europe, CIS, Middle East and Africa) and 9 countries in ITU Region 3 (Asia Pacific). In ITU Region 2 (Americas), no identification in the mentioned band was made to IMT, however, 14 countries included their country names in a footnote upgrading the mobile service into primary status in the band 3 400-3 500 MHz (Note: mobile service in the band 3 500-3 600 MHz is already allocated on a primary status). As a result of the above outcome, appropriate measures should be taken in order to ensure that satellite earth stations are protected from IMT operations, i.e. registration of earth stations on or near the borders of those administrations that have included their country name in the footnote identifying IMT in the band 3 400-3 600 MHz. A description on the procedures to register satellite earth stations at the ITU is provided in Section 3 below. Since the band 3 400-3 600 MHz is a downlink (space-to-Earth) band for satellite services, the task mentioned above will primarily be concentrated on the procedures required for receiving earth stations. 2. Relevant ITU Provisions 9.17 – for any specific earth station or typical mobile earth station in frequency bands above 100 MHz allocated with equal rights to space and terrestrial services, in respect of terrestrial services, where the coordination area of the earth station includes the territory of another country, with the exception of the coordination under No. 9.15 9.28 – In the case of requests for coordination under No. 9.29, the requesting administration shall, by applying the calculation method and criteria contained in Appendix 5 to those frequency assignments, identify, to the extent possible, the administrations with which coordination is to be effected. 9.29 – Request for coordination made under Nos. 9.15 to 9.19 shall be sent by the requesting administration to the identified administrations, together with the appropriate information listed in Appendix 4 to the Regulations. 9.31 – The information sent under No. 9.29 shall also, in the cases covered by Nos. 9.15, 9.17 or 9.17A, include a copy of diagrams drawn to appropriate scale indicating, for both transmission and reception, the location of the earth station and its associated coordination area, or the coordination area related to the service area in which it is intended to operate the mobile earth station, and the data on which the diagrams are based. In respect of terrestrial stations, in the cases covered by Nos. 9.16, 9.18 and 9.19 the information shall include the locations of terrestrial stations within the coordination area of the relevant earth station. 9.32A – If the responsible administration, following the application of Nos. 9.15 to 9.19, concludes that coordination is not required, it may send the relevant information pursuant to Appendix 4 to the Bureau for action under Section I of Article 11. Page 1 9.33 – If for any reason an administration cannot act in accordance with No. 9.29, it shall seek the assistance of the Bureau. The Bureau shall then send the request for coordination to the administration concerned and take any necessary further action as appropriate under Nos. 9.45 and 9.46. 9.45 – An administration receiving a request for coordination under No. 9.29 shall, within 30 days from the date of the request, acknowledge receipt by telegram to the requesting administration. In the absence of an acknowledgement of receipt of its request within the 30 days, the requesting administration shall send a telegram requesting an acknowledgement. 9.46 – If there is no acknowledgement of receipt within 15 days of its second request sent under No. 9.45, the requesting administration may seek the assistance of the Bureau. In this event, the Bureau shall forthwith send a telegram to the administration which has failed to reply requesting an immediate acknowledgement. 9.47 – If there is no acknowledgement of receipt within 30 days after the Bureau’s action under No. 9.46, it shall be deemed that the administration which has failed to acknowledge receipt has undertaken: 9.48 – a) that no complaint will be made in respect of any harmful interference affecting its own assignments which may be caused by the assignment for which coordination was requested; and 9.49 – b) that the use of its own assignments will not cause harmful interference to the assignment for which coordination was requested. 11.25 – Notices relating to assignments to stations in space services, and to terrestrial stations involved in coordination with a satellite network, shall reach the Bureau not earlier than three years before the assignments are brought into use. §6 e) iii) of Appendix 5 – to bring into use a new frequency assignment to a receiving earth station and the notifying administration states that it accepts the interference resulting from existing and future terrestrial station assignments or assignments of earth stations operating in the opposite direction of transmission. In such case, administrations responsible for the terrestrial stations of earth stations operating in the opposite direction of transmission are not required to apply the provisions of No, 9.18 or 9.17A of Article 9 respectively. 3. Procedures to register an earth station According to provision No. 9.17 of the Radio Regulations, prior to the registration of earth station assignments in the Master International Frequency Register (MIFR), coordination will need to be effected. This requires the generation of a coordination area of the earth station and obtaining agreement from administration(s) whose territory/territories lie(s) within the generated coordination area. Due to provision No. 11.25, the administration responsible for the terrestrial stations can, during the coordination process, request the inclusion of terrestrials stations (in this case IMT stations) that are not yet recorded in the MIFR but are planned to be brought into use within the next 3 years. Page 2 The procedures for effecting coordination of earth stations with respect to terrestrial stations are as follows, noting that coordination of earth stations with respect to terrestrial stations is based on the concept of a coordination area: a) Completion of the coordination data (Appendix 4 Annex 2); b) Preparation of the coordination contours (Appendix 7 or R1448 software); c) Providing the coordination information to administrations whose territory falls within the coordination area; d) Action taken by informed administration (those receiving the coordination information); e) Consultation between the notifying and informed administrations, as required; f) Conclusion of the coordination agreement; g) Notification under No. 11.2 and thereafter recording in the MIFR. It should be noted that while it is possible to register and notify receive only earth stations, it is not possible to register and notify typical earth stations (only typical mobile earth stations can be registered and notified). Since the band 3 400-3 600 MHz is not allocated to the Mobile-Satellite Service, it would not be possible to register typical mobile earth stations in this case. Another important point to note is that the protection of satellite earth stations does not take into account out-of-band interference scenario, i.e. earth stations registered in the bands above 3 600 MHz will not be protected by terrestrial stations operating in the band 3 400-3 600 MHz (in terms of ITU examination). Thus it is important that the registration and recording of the earth station assignments include the overlapping band 3 400-3 600 MHz.
