ERC Recommendation 12-03

Scope of recommendation
Harmonised Radio Frequency Channel Arrangements for Digital Terrestrial Fixed Systems Operating in the Band 17.7 - 19.7 GHz

Annex Frequency Bands FDD and/or TDD P-P and/or P-MP Notes
1 17700 MHz - 18700 MHz and 18700 MHz - 19700 MHz FDD Low, medium and high capacity digital systems For low capacity digital systems there exist many links among CEPT countries using various arrangements according to Recommends 6 of ITU-R Rec. F. 595
2 17700 MHz - 18700 MHz and 18700 MHz - 19700 MHz FDD Low, medium and high capacity digital systems

Note 1 When an interleaved channel arrangement is used, the values of the centre frequencies of these radio-frequency channels should be below those of the corresponding channel frequencies (as detailed in Annex 1) by a value of half the channel spacing.
Note 2 Two adjacent 110 MHz channels can be merged to create one 220 MHz channel with its centre frequency between the merged channels. The numbering is just for identification of the channelling and wo consecutive channel numbers cannot be used on the same physical link due to channels overlap (see Annex 2).
Note 3 To assist cross-border co-ordination, administrations may refer to the channel identifiers described in Annex 2.
