1、69 Page E 1 Recommendation T/R 02-01 (Odense 1986) PLANNING AND COORDINATION OF LAND MOBILE (AND OTHER) SERVICES OPERATING IN THE BAND 47-68 MHz Recommendation proposed by the “Radiocoinmiinications” Working Group T/WG 3 (R) Text of the Recommendation adopted by the “Telecommiinications” Commission:
2、 “The European Conference of Postal and Telecommunications Administrations, considering (a) that the WARC (Geneva 1979) in Footnote 554 of the Radio Regulations additionally allocated the band (b) that the band 47-68 MHz will in the majority of CEPT countries continue to be used for television broad
3、casting (c) that in some CEPT countries the Plans for land mobile services in this band are at an early stage of development, (d) that it is desirable to achieve harmonised channel arrangements for the land mobile services in CEPT member (e) that such arrangements will ease the problems of coordinat
4、ion, especially in border areas, thus minimising delays (f) that wherever possible assigned frequencies should follow a uniform pattern in all CEPT countries, (g) that the use of the same modulation method would facilitate coordination between Administrations, (h) that in order to reduce the possibi
5、lity of harmful interference occurring the lowest possible antenna height and the minimum possible radiated power should generally be iitilised, (i) that it is important to examine the most recent propagation information and the minimum necessary field strength values to be protected for the require
6、d grade of service, (j) that additionally there is a requirement in some CEPT countries for low power services in the band 47-50 MHz, (k) that some CEPT countries intend to use parts of this frequency band in accordance with Radio Regulation 342 for the amateur service and therefore there is a need
7、to harmonise these allocations within the band 50-54 MHz, 47-68 MHz to the land mobile service on a permitted basis in the majority of CEPT countries, for the foreseeable fiiture, countries, in the agreement of assignments in these geographical regions, recommends to facilitate the coordination of a
8、ssignments in border regions in the band 47-68 MHz: 1. that the plan detailed in Annex A should be utilised wherever possible in CEPT member countries, 2. that the maximum channel spacing shall be 25 kHz and that, when frequency or phase modulation is used, Administrations should assign frequencies
9、in the series: 47,000 MHz + n x 12.5 kHz (n = 1, 2, 3, 4, .) for 12.5 kHz channel arrangements (n = 1, 3, 5, 7, .) for 25 IcHz channel arrangements, 3. that frequency or phase modulation should generally be used, 4. that except for the services in paragraphs 5. and 6. below the effective radiated po
10、wer (erp) of stations of the land mobile service should whenever practicable not exceed 25 watts, 5. that the effective radiated power for on site paging applications should whenever practicable not exceed 5 watts, 6. that the effective radiated power for low power applications other than that menti
