-The band 1427-1530 MHz is allocated to the Fixed service on a primary basis; the band 1530-1535 MHz is allocated to the Fixed service on a secondarybasis.

-The band 1427-1435 MHz is also allocated to other services as follows:

1427-1429: Mobile except aeronautical mobile, Space Operation (Earth-to-space)

1429-1452: Mobile

1452-1492: BROADCASTING, BROADCASTING-SATELLITE, Mobile

1492-1525: Mobile

1525-1530: SPACE OPERATION (space-to-Earth), MOBILE-SATELLITE (space-to-Earth), Earth Exploration –Satellite, Mobile

1530-1533: SPACE OPERATION(space-to-Earth), Maritime Mobile-Satellite (space-to-Earth), Land Mobile –Satellite (space-to-Earth), Earth exploration-Satellite, Mobile

1533-1535MHz: SPACE OPERATION (space-to-Earth), MARITIME MOBILE-SATELLITE (space-to-Earth), Land Mobile-Satellite (space-to-Earth), Earth Exploration-Satellite, Mobile

Channel arrangement for microwave systems in the band 1530-1535 MHzis under consideration.

3.3.1.1 The band 1427-1530MHz

NOTE:

·This radio-frequency channel arrangement complies with Recommendation ITU-RF.1242, 1997

·Application: point-to-point digital microwave systems

·Transmission capacity: 2x2 Mbps

·Minimum transmission distance: 30 km

• The centre frequencies in MHz of individual channels are expressed by the following relationships:

f_n = f ₀- 47.5 + 4nf₀=1472 MHz

f_n¢= f₀+17.5 +4nn = 1, 2, 3, 4, 5, 6
