2、ns Administrations, Introduction The frequency band 1452-1492 MHz was allocated to the broadcasting-satellite service and on a complementary basis to the broadcasting service dedicated to digital audio broadcasting (DAB) by the WARC (Geneva, 1992). The effective date of this allocation for Region 1

3、was brought forward to 1 January 1997 by the WRC (Geneva. 1995). The lower sub-band of this frequency band was allotted by the T-DAB Planning Meeting, Wiesbaden, 1993, for terrestrial DAB applications. The frequency band 1474-1481.5 MHz has been used for some time in a number of countries for teleme

4、try applications for the transmission of data between ground stations and aircraft (ground - air - ground) and therefore with long ranges. A new frequency band needs to be found in the medium and long term for these airborne telemetry applications. Owing to the specific nature of these applications,

5、 this frequency band should be hannonised as far as possible on a pan-European basis but should not be subject for an ERC Decision, “The European Conference of Postal and Telecommunications Administrations, cons idering that civil and military airborne telemetry applications are currently operated i

6、n a number of CEPT countries in the frequency band 1474-1481.5 MHz; that the frequency band 1452- 1467.5 MHz has been allotted for terrestrial digital audio broadcasting (T- DAB) and that the possibility of an extension above 1467.5 MHz in the medium term is not excluded; that T-DAB emissions and te

7、lemetry emissions in the same frequency band and on band edges of adjacent frequency bands are not compatible with each other; that a new frequency band needs to be designated for airborne telemetry applications in a number of CEPT countries for this reason; that based on technical development (high

8、er data rates) the spectnim demand for these civil and military airborne radio applications increased; that similar civil and military airborne radio applications as operated in the frequency band 1474-1481.5 MHz are currently operated in some other countries in the frequency bands around 2.3 GHz; t

9、hat in some CEPT countries fixed links operating in the bands 2100-2400 MHz will cease operation around or shortly after the year 2000 whereas in other countries fixed links will continue to operate; that the ERC Report 25 states in the major utilisation column for the frequency band 2300-2400 MHz t

10、hat parts of the band are used for aeronautical telemetry on a national basis; that it is in the interest of some CEPT countries to harmonise in the medium and long term the frequency bands for these telemetry applications as far as possible; that in a few CEPT countries the frequency band 2290-2300

11、 MHz is used by deep space applications which needs to be protected from unwanted emissions of airborne-telemetry applications; Editioii of Febriian I O. 1998 STD-CEPT CEPT/ERC/REC 62-02 E-ENGL 1998 m 232b41q 0013138 643 = CEPT/ERC/REC 62-02 E Page 2 Distribution 6 k) that the CEPT/ERC Recommendatio
