Recommendation T/R 13-02

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
A1 (FDD) 22000 MHz - 22600 MHz and 23000 MHz - 23600 MHz FDD P-P and/or P-MP
A2 (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.
A3 (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.
B (FDD) 24500 MHz - 25500 MHz and 25500 MHz - 26500 MHz FDD P-P and/or P-MP
C (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

Note 1 In order to maximise the spectrum resources for Fixed Service (FS) applications, CEPT Aministrations may consider to use also the band 22.6 - 23.0 GHz (23 GHz band center-gap), for optimizing the deployment of unidirectional links such as those for ENG/OB- SAP/SAB applications as well as of bidirectional conventional point-to-point links
