Key features — The following list identifies the key features of the satellite component [77, 79, 80]:

1.Coverage of any one satellite will be much larger than that of any cluster of terrestrial base stations.

2.Coverage is likely to be by means of a number of spot beams, which will form megacells, with each spot beam larger than any terrestrial macrocell.

3.Satellite coverage can be regional, multiregional, or global.

4.A range of orbit constellations may be used.

5.The number of LES will be limited.

6.The terrestrial and satellite components should be optimized with respect to each other.

7.The LESs will connect to the satellites using feeder links that operate in frequency bands outside those identified for IMT-2000 operation; the feeder link frequencies may be used by other satellite systems and terrestrial systems, with appropriate sharing criteria.

8.Inter-satellite links (ISLs), if used, will operate outside the IMT-2000 band.

9.Provisions must exist to allow multiple service providers to compete in the satellite component.
