scope:

This European Telecommunication Standard (ETS) specifies the minimum technical requirements of the radio interface that the TFTS shall support to provide a pan-European terrestrial aeronautical public correspondence service. This ETS contains the specification of equipment for the provision of a terrestrial aeronautical public correspondence service working in the frequency spectrum bands allocated at the World Administrative Radio Conference 1992 (WARC 92) (1 670 - 1 675 MHz and 1 800 - 1 805 MHz). This ETS fully specifies aspects of the radio interface and TFTS ground network required to maintain inter-operability of equipment. European Radio Committee (ERC) Decision ERC/DEC (92)01 [29] is applicable to the TFTS frequency spectrum within Europe. EN 300 789 [28] covers aspects of conformance testing for TFTS aircraft mobile stations. The specification of data application and facsimile is the subject of I-ES 200 794 [34]. The delivery mechanism for Packet Data Services is defined in ETS 300 752 [33].
