ERC Recommendation 12-03

ERC Recommendation 12-03, annex A; ETSI EN 302 217
To reduce interference with fixed satellite service, the ATPC shall be applied, Decision ERC Decision (00) 07, annex 1
BiH: Priority, access links in public mobile commercial networks

Channel spacing 220 MHz, 7 MHz and 3,5 MHz are harmonized with ITU-R F.595-9. 
The band is shared FSS/FS

ERC/REC 12-03 channel plan is used with additional 6.875 MHz raster. Frequencies (MHz) of individual channels in that frequency raster are expressed by following relationship:
f0 = 18700
fn = f0 – 1000 + 6.875*n
fn’ = f0 + 10 + 6.875*n
n = 1….140
There are also some small adjustments in centre frequencies of 6.875 MHz frequency raster within operators block assignments.

The actual radio frequency channel arrangements are based on ERC/REC 12-03 and ITU-R Rec. F.595-9. The duplex gap is occupied by the radio channels with centre frequencies 18 705 MHz, 18 715 MHz, 18 725 MHz, 18 735 MHz and with the bandwidth of 10 MHz.

In addition, 7.5 MHz and 5 MHz channel widths are used.

Finland is using also 15 MHz and 7.5 MHz channel spacing.

Additional channeling arrangements of 1.75, 3.5 and 7 MHz as per "recommends 2"

Implemented through reference in the National Frequency Allocation Table
Configuration PP

7.5 MHz channelling: Y1.
Channel centre frequencies according to:
ITU-R Rec. F.595, Annex 4.
From 17743.750 MHz to 17796.250 MHz / 18753.750 MHz to 18806.250 MHz.

Block assignment in part of the band

National plan: FDD 56 MHz instead of FDD 55 MHz, FDD 28 MHz instead of FDD 27.5 MHz, 14 MHz FDD instead of FDD 13.75 MHz; FDD 110 MHz and FDD 220 MHz channel bandwidth are not used

Slovakia is using also 7.5 MHz and 5 MHz channel spacing. The allocation is subject to coordination under the HCM Agreement.

Spain 13.75 MHz channel arrangement plus 7 MHz channels

Channel spacing 6.875 MHz is implemented in accordance with a national channelling arrangement:

7.5 MHz channelling: Y1.
Channel centre frequencies according to:
ITU-R Rec. F.595, Annex 4.
From 17743.750 MHz to 17796.250 MHz / 18753.750 MHz to 18806.250 MHz.

3.5 MHz and 7.0 MHz channel rasters are also used in accordance with the arrangements set out in Annex 3 to ITU-R Recommendation F.595. There are also other national/legacy channel arrangements in use including 7, 10, 20 and 55 MHz, which range from 17.7275 GHz to 19.5075 GHz.
