1、Recommendation T/R 22-05 (Madrid 1992) FREQUENCIES FOR MOBILE DIGITAL TRUNKED RADIO SYSTEMS Recommendation proposed by the Frequency Management“ Working Group (FIM) Text of the Recommendation aopted by the “European Radiocommunications Committee “ (ERC): “The European Conference of Postal and Teleco
2、mmunications Administrations, considering a) that the use of trunked systems can improve spectmm efficiency and increase the quality of service provided to users of mobile radio, b) that the introduction of new digital technology will allow the provision of a wide range of new services, c) that the
3、use of harmonised frequency bands would ease frequency coordination, d) that the spectmm below 1 GHz is already used intensively according to different frequency plans, e) that at present a common harmonised frequency band is not available, f) that nevertheless the availability of a small numk of fr
4、equency bands within common tuning ranges should satisfy initial market demands and help reduce the cost of equipment, g) that common tuning ranges would enable the possibility of mobile units to operate in more than one area h) CEF Recommendations T/R 25-08 E and TIR 75-02 E!, corntry, noting that
5、ETSI has indicated advantages in the use of frequencies below 500 MHz, recommends 1. 410-420/420-430 MHz 450-460/460-470 MHz that frequencies should be made available in parts of one or more of the following bands: 380-390/390-400 MHz 870-8881915-933 MHz, 2. 3. that the fiequency use conforms, as ap
6、propriate, to CEPT Recommendation T/R 25-08 E, Annex 2, that frequencies should be made available according to market demand with adequate provision to ailow the introduction of Mobile Digital Trunked Radio Systems in 1995. recommends further that ETSI, in developing standards for equipment, should
7、take into account the fact that it will be necessary to introduce Mobiie Digital Trunked Radio Systems into small blocks of spectrum in the frequency bands alongside blocks retained by existing users.“ Edition of March 1.1993 2326414 0014L3b 768 Adm AUT BEL CZE D Trn 22-05 Frequencies for mobile digital trunked radio systems Imp1 Remarks Yes Yes Planned No DNK E EST F FIN Yes Superseded by ERC-Decision No Planned YeS Partial implementation Yes G HNG HOL HRV I IRL ISL Planned Yes Partial implementation Yes Planned Planned Planned Yes
