1、Recommendation T/R 13-01 E (Montreux 1993) PREFERRED CHANNEL ARRANGEMENTS FOR FIXED SERVICES IN THE RANGE 1-3 GHz Recommendation proposed by the Working Group “Prequency Management“ (FM) Text of the Recommendation adopted by the “European Radiocommunications Committee“ (ERC): The European Conference
2、 of Postal and Telecornmunications Administrations, considering: 1) that following decisions taken at WARC-92, new fixed service channelling arrangements are required in the range 1 - 3 GHz in order to enable future new services to be accommodated; 2) that there are technical and economic factors th
3、at will require continued operation of fixed services in the 1-3 GHz range; 3) that there is a range of different fixed service applications, requiring various channel bandwidths, which need to be accommodated in the 1 - 3 GHz range. noting a) that in the context of this recommendation the guard ban
4、d is defined as the frequency difference between the edge of the band and the channel edge; b) that the separation band is defined as the band between the go and return halves, from edge of the bands used by other services; c) that the centre gap is defined as the frequency difference between the up
5、per and lower channel edges of the go and return halves of the band; d) that TX/RX separation is defined as the frequency separation between the centre frequency of the transmitter and the centre frequency of the associated receiver. recommends: 1) that the fixed service in the band 1350 - 1375 MHz
6、paired with 1492 - 1517 MHz should be operated in accordance with the channel plan given in Annex A; Edition of February 1, 1994 STD-CEPT TIR 13-01 E-ENGL 3974 2326434 0034589 b2b Page 2 2) that the fixed service in the band 1375 - 1400 MHz paired with 1427 - 1452 MHz should be operated in accordanc
7、e with the channel plan given in Annex B; 3) that the fixed service in the band 2025 - 21 10 MHz paired with 2200 - 2290 MHz should be operated in accordance with the channel plan given in Annex Ci; 4) that the fixed service in the band 2520 - 2593 MHz paired with 2597 - 2670 MHz should be operated
8、in accordance with the channel plan given in Annex D.

10、mission it will be limited to low capacity digital systems for point-to-point and point-to-multipoint systems. The basic pattern of the proposed channel arrangement is a symmetric 2 MHz raster based on CCIR Recommendation 701 which offers the maximum amount of possible channels. Further channel plan
11、s for the transmission of lower bit rates are derived from the basic pattern by means of subdivision.
