Appendix C : Cross boarder coordination

 

 

The following is extracted from ECC/REC (11)05 as an operational example and may be adapted for the SADC-countries.

 

 

FIELD STRENGTH LEVELS FOR THE CROSS-BORDER OPERATION BETWEEN FDD MFCN SYSTEMS IN THE FREQUENCY BAND 2500-2690 MHZ

 

1. Stations of FDD systems with centre frequencies not aligned on both sides of the borderline or with centre frequencies aligned using preferential PCI codes given in Annex 5 may be used without coordination with a neighbouring country if the mean field strength produced by the cell (all transmitters within the sector) does not exceed the value of 65 dBμV/m/5MHz at a height of 3 m above ground at the borderline between countries and does not exceed a value of 49 dBμV/m/5MHz at a height of 3 m above ground at a distance of 6 km inside the neighbouring country.

 

2. Stations of MFCN FDD systems with centre frequencies aligned on both sides of the borderline using non-preferential PCI codes may be used without coordination with a neighbouring country if the mean field strength produced by the cell (all transmitters within the sector) does not exceed the value of 49 dBμV/m/5 MHz at a height of 3 m above ground at the borderline between countries.

 

3. It is usually not considered necessary to define preferential frequencies.

 

4. If administrations wish to agree on frequency coordination based on preferential frequencies, while ensuring a fair treatment of different licensees then they can do so based on mutual agreements. In this case field strength levels in paragraph 1 above may be applicable.

 

FIELD STRENGTH LEVELS FOR THE CROSS-BORDER OPERATION BETWEEN TDD MFCN AND BETWEEN TDD AND FDD MFCN SYSTEMS IN THE FREQUENCY BAND 2500-2690 MHZ

 

1. In general, stations of MFCN systems may be operated without coordination if the mean field strength produced by the cell (all transmitters within the sector) does not exceed the value of 30 dBμV/m/5 MHz at 3 metres above ground level at the borderline.

 

2. If administrations wish to agree on frequency coordination based on preferential frequencies, or MFCN TDD systems are in operation across both sides of a border and are synchronised across the border, or MFCN TDD systems are deployed as downlink only on both sides of the border, then field strength levels of 65 dBmV/m/5 MHz@0 km and 49 dBmV/m/5 MHz@6 km are to be applied.

 

3. If the values in 2 above are not acceptable, field strength levels should be agreed on a bi- or multilateral basis.

 

4. TDD operation within the bands 2500-2570 MHz and 2620-2690 MHz has not been studied with FDD operation.

 

5. TDD operation within these bands will only occur if countries do not adopt the channelling arrangement in ECC/DEC/ (05)05. In this case the field strength levels should be agreed on a bi-or multilateral basis.
