The following bands are identified for use by high-density applications (HDFSS) in the fixed-satellite service:
17.3 – 17.7 GHz (space-to-Earth) in Region 1,
18.3 – 19.3 GHz (space-to-Earth) in Region 2,
19.7 – 20.2 GHz (space-to-Earth) in all Regions,
39.5 – 40 GHz (space-to-Earth) in Region 1,
40 – 40.5 GHz (space-to-Earth) in all Regions,
40.5 – 42 GHz (space-to-Earth) in Region 2,
47.5 – 47.9 GHz (space-to-Earth) in Region 1,
48.2 – 48.54 GHz (space-to-Earth) in Region 1,
49.44 – 50.2 GHz (space-to-Earth) in Region 1,
And
27.5 – 27.82 GHz (Earth-to-space) in Region 1,
28.35 – 28.45 GHz (Earth-to-space) in Region 2,
28.45 – 28.94 GHz (Earth-to-space) in all Regions,
28.94 – 29.1 GHz (Earth-to-space) in Region 2 and 3,
29.25 – 29.46 GHz (Earth-to-space) in Region 2,
29.46 – 30 GHz (Earth-to-space) in all Regions,
48.2 – 50.2 GHz (Earth-to-space) in Region 2.
This identification does not preclude the use of these bands by other fixed-satellite service applications or by other services to which these bands are allocated on a co-primary basis and in RR does not establish priority among users of the bands. Administrations should take this into account when considering regulatory provisions in relation to these bands. See Resolution 143.
