2、nt” (FM) Text of the Recommendation adopted by the “European Radiocommunications Committee (ERC) : “The European Conference of Postal and Telecommunications Administrations, considering (a) that the WARC (Geneva, 1979) in Article 8 of the Radio Regulations also allocated the band 862-960 MHz to the

3、mobile, except aeronautical mobile service, (b) that this band is the only band currently available in the majority of CEPT countries to meet the anticipated growth in land and maritime mobile systems, (c) that it is desirable to achieve a harmonised use of frequency allocations for the land mobile

4、service in CEPT member countries, (d) that CEPT countries intend to introduce the GSM public land mobile cellular system in the foreseeable future, and that this system could also provide an automatic public correspondence service for vessels in European waters, (e) that several CEPT countries have

5、implemented, or intend to introduce early public land mobile cellular systems in the 900 MHz band, (f) that there is a need for non public land mobile radio systems in the 900 MHz band, (g) that analogue cordless telephones are being used or introduced in the 900 MHz band in accordance with (h) that

6、 there is a need for a single frequency and two frequency short range radio (SRR) system, (i) that there is a need for low power narrowband and wideband telecommand and telecontrol in the 900 MHz band, (j) that some CEPT countries have introduced Citizens Band (CB) operations in the 900 MHz band, (k

7、) that the gradual implementation of narrow and wideband digital techniques in the presence of existing analogue Recommendation TIR 24-03 E, systems requires flexibility in determining appropriate frequency allocations, noting that this frequency band may continue to be used in a number of CEPT coun

8、tries for the ked service and consequentially the rapid introduction of mobile services in all of the sub-bands as recommended below may be difficult, recommends in order to achieve a harmonised use of the frequency band 862-960 MHz in CEPT countries, 1. that the sub-bands 870-888 MHz and 890-915 MH

9、z (mobile station transmit) shall be paired with the sub-bands 915-933 MHz and 935-960 MHz (base station transmit) respectively with a transmit receive spacing of 45 MHz, 2. that the sub-bands 905-914 MHz and 950-959 MHz be reserved in all CEPT countries for the commencement of the public mobile cel

10、lular GSM system and that the sub-bands 890-915 MHz and 935-960 MHz provide the expanded allocation for the GSM in the future, 3. that the sub-bands 890-905 MHz paired with 935-950 MHz be utilised for early analogue public cellular land mobile systems. To simplify coordination between Administration

12、. To simplify coordination between Administrations analogue systems should be implemented starting from the upper end of the sub-band and digital systems be implemented starting from the lower end of the sub-band, that the sub-band 862-870 MHz be generally used for single frequency land mobile syste

13、ms.

16、s (see recommends 6 above). that on a national basis Administrations may authorise parts of the sub-bands 875-888 MHz paired with 920- 933 MHz to be used for expansion for the GSM system in the future, when the GSM bands between 935- 960 MHz paired with 890-915 MHz are fully utilised for the GSM sys
