Sub-band a1): The user interface of SRD permit as a minimum the selection of any and all possible frequencies within the 88.1 MHz to 107.9 MHz and as a maximum 87.6 MHz to 107.9 MHz. When audio signals are not present, apparatus must employ a transmission time out facility. Pilot tones that ensure continuity of transmission are not permitted. Sub-band d): ECC Report 230 provides information on ALD frequency issues in the frequency band 174-216 MHz including an example for an on-site measurement procedure. It should be noted that ALD applications may need to move in frequency if changes in the use of the broadcast radio service take place. Sub-bands f1) and f2): ECC/DEC/(15)01 identifies the band 703-733 MHz/758-788 MHz for the introduction of mobile/fixed communication networks (MFCN). Some national administrations which have not introduced mobile/fixed communication networks (MFCN) in accordance with Decision ECC/DEC/(15)01 may authorise larger parts or the whole of the band 694-790 MHz to be used by radio microphones. Sub-bands f2), f3), f4): Some national administrations which have not introduced mobile/fixed communication networks (MFCN) in accordance with Decision ECC/DEC/(09)03 may authorise larger parts or the whole of the band 786-862 MHz to be used by radio microphones. Sub-band h2): this frequency band is identified for the introduction of communication networks supplemental downlink (MFCN SDL) in ECC Decision (17)06. National administrations may authorise radio microphones in the band as long as they will not have introduced mobile/fixed communication networks (MFCN).
