Disadvantages of satellite communication
(1) The antenna elevation angles of the earth stations are not the same. Therefore, regardless of the ground distance between two earth stations (7200KM), the propagation delay from one earth station to another earth station via satellite is 250 -Between 300ms, this is quite different from other communications.
(2) The frequency band above 10GHZ is affected by rain and snow.
(3) The antenna is affected by solar noise.
