5、mmunications Ahnautiques (SITA), are working closely with ETSI on the introduction of TFTS, that it is necessary to provide a common frequency spectrum designation for the provision of a pan- European TPTS, that market studies have indicated that the required spectrum will be as 2 x 1 MHz by 1993,2
6、x 3 MHZ by 1994and25MHzby1998, that the WARC (MOB-87) frequency specrum allocations for TFTS were provided for pre-operational and experimental systems, and do not enable the expansion of TFS, that the use of WARC (MOB-87) fiequency spectrum allocations may result in harmful interference to primary
7、services within those bands, that consideration of frequency bands in 1-3 GHz to the TFTS is included on the agenda of the WARC-92 under item 2.2.4.b, that the implementation of the TFS should not cause harmful interference to the services in the adjacent bands, Edition of October 31.1991 STD=CEPT T

9、 the outcome of WARC-92, the frequency bands 1.670-1.675 MHz (for aeronautical station transmitters) and 1.800-1.805 MHz (for aircraft station transmitters) be designated for TFTS. Frequencies should be made available in accordance with market demands as follows: 2 x 1 MHz from 1993 2 x 3 MHz from 1
10、994 2 x 5 MHz from 1998 Where necessary, Administrations should take existing national services into account when planning bands to be made available for the TFTS, 2. that the use of the above frequencies for TFTS must not result in harmful interference to the Services which operate in adjacent freq
