In the example, the coverage range of each satellite intersects
that of the other three. To not create transmission problems,
different Group numbers are given to adjacent satellites.
As a result, when a data transmission takes place between
satellites 101 and 105 (which are not adjacent) and the
respective terminals, SysTools™2001 disables transmission
between satellites 102, 103, 104 and 106; it then enables
transmission from 102 and 105 and disables transmission
from the other satellites, and so on.
