Scope of recommendation
Preferred Channel Arrangements for the FS operating in the Frequency Band 22.0 to 29.5 GHz
| Annex | Frequency Bands | FDD and/or TDD | P-P and/or P-MP | Notes |
|---|---|---|---|---|
| 1 A1.1 (FDD) | 22000 MHz - 22600 MHz and 23000 MHz - 23600 MHz | FDD | P-P and/or P-MP | |
| 1 A1.2 (FDD) | 22590.75 MHz - 22758.75 MHz and 22842.75 MHz - 23010.75 MHz | FDD | P-P and/or P-MP | The channels are shown as paired; however, administrations may envisage unpaired use of those channels according the national need (e.g. for ENG/OB-SAP/SAB applications). Some administrations may also wish to pair some of the lower channels within the 22.6 - 23.0 GHz band with the 21.2 - 21.4 GHz band which is outside the scope of this recommendation. |
| 1 A1.3 (TDD centre gap) | 22758.75 MHz - 22842.75 MHz | TDD | P-P | This band is the centre gap of the channel arrangement in section A2 which may be used for unpaired channels. |
| 2 (FDD) | 24500 MHz - 25500 MHz and 25500 MHz - 26500 MHz | FDD | P-P and/or P-MP | |
| 3 (FDD) | 27500 MHz - 28500 MHz and 28500 MHz - 29500 MHz | FDD | P-P and/or P-MP | ECC/DEC/(05)01 has defined a band segmentation as sharing condition between FS and FSS in this band; consequently, in CEPT countries implementing that Decision, part of the channels described above may no longer be available. Accordingly the following paired channels might be unavailable: 112 MHz arrangement: channels 1 through 4 paired with 1’ through 4’; 56 MHz arrangement: channels 1 through 7 paired with 1’ through 7’; 28 MHz arrangement: channels 1 through 14 paired with 1’ through 14’; 14 MHz arrangement: channels 1 through 28 paired with 1’ through 28’; 7 MHz arrangement: channels 1 through 56 paired with 1’ through 56’; 3.5 MHz arrangement: channels 1 through 112 paired with 1’ through 112’; and the following channels may remain available only unpaired (for unidirectional links): 112 MHz arrangement: channel 4; 56 MHz arrangement: channels 6 and 7; 28 MHz arrangement: channels 11 through 14; 14 MHz arrangement: channels 22 through 28; 7 MHz arrangement: channels 44 through 56; 3.5 MHz arrangement: channels 88 through 112 |
| 4 (FDD) | 22000 MHz - 22600 MHz and 23000 MHz - 23600 MHz | FDD | P-P and/or P-MP | |
| 5 (FDD) | 27500 MHz - 28500 MHz and 28500 MHz - 29500 MHz | FDD | P-P and/or P-MP |
| Note 1 | In order to maximise the spectrum resources for Fixed Service (FS) applications, CEPT administrations may consider to use also the band 22.6 - 23.0 GHz (23 GHz band centre gap), for optimising the deployment of unidirectional links such as those for ENG/OB- SAP/SAB applications as well as of bidirectional conventional point-to-point links |
| Note 2 | To assist cross-border co-ordination, administrations may refer to the channel identifiers described in Annex 4 and Annex 5. |
| Note 3 | Two adjacent 112 MHz channels can be merged to create one 224 MHz channel with its centre frequency between the merged channels. The numbering is just for identification of the channelling and two consecutive channel numbers cannot be used on the same physical link due to channels overlap (see Annex 4 and Annex 5). |
