✴ Satellite communications is the use of satellite technology in the field of communications. The services provided by satellite communications are voice and video calling internet fax television and radio channels.✴

► Satellite communications can provide communication capabilities spanning long distances and can operate under circumstances or conditions which are inoperable for other forms of communication.✦

► A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder; it creates a communication channel between a source transmitter and a receiver at different locations on Earth.✦

► Wireless communication uses electromagnetic waves to carry signals. These waves require line-of-sight and are thus obstructed by the curvature of the Earth. The purpose of communications satellites is to relay the signal around the curve of the Earth allowing communication between widely separated points.✦
