Principles of Coordination. Concerning usage of the frequency band 2500-2690 MHz in boarder areas for MFCN systems the relevant provisions of ECC Recommendation ECC/REC/(11)05 (version being in force at the time of signing this Technical Agreement is attached for reference) and this Technical Agreement shall be applied. In order to assure equitable access to the spectrum and operations without harmful interference and to enhance the efficiency of spectrum usage in border areas the principles of field strength trigger values and preferential code groups shall be applicable. Neither coordination nor notification of the MFCN base stations in boarder areas is required if the field strength trigger values given in Section 3.1 of this Technical Agreement are fulfilled. If the field strength trigger values are exceeded coordination is required and the procedure detailed in Annex 4 of ECC Recommendation ECC/REC/(11)05 should be applied. Preferential use of frequencies as laid down in Annex 1 of ECC Recommendation ECC/REC/(11)05 shall not be the subject of this Technical Agreement but may be subject of Operator arrangements (see Section 7 of this Technical Agreement). The relevant provisions of the bi- or multilateral agreements, arrangements or protocols dealing with frequency coordination in general (e.g. the “HCM Agreement”), previously approved by all Signatory Authorities, shall be applied unless otherwise laid down in this Technical Agreement.
Principles of Coordination. The following basic principles have been agreed upon regarding the coordination of the IRIDIUM System7 with the Arecibo Radio Astronomy Observatory (“Arecibo”):
