Define satellite Communication.

1.	Define satellite Communication.
Answer» 1. Line of sight required between satellite and earth stations. 2. 12 to 24 transponders per satellite. These transponders receive, amplify, change frequency and transmit. 3. Geosynchronous orbit (22,300 miles). 4. Low security—anyone with satellite dish and right frequency can tune in. 5. Ease of adding stations. 6. Data rates of up to 50 Mbps. 7. Microwave signal at 6 GHz is beamed to it from a transmitter on the earth. It is amplified and retransmitted to the earth at 4 GHz by a system called a transponder mounted on the satellite to avoid interference.
