- The coverage area of a satellite greatly exceeds that of a terrestrial system.
- Transmission cost of a satellite is independent of the distance from the center of the coverage area.
- Satellite to Satellite communication is very precise.
What is the difference between terrestrial and satellite communication?
In a satellite link delay from earth to satellite to earth is about 240ms while
in terrestrial link it will be far less
. But transmission cost in a satellite system is independent of the distance within the area of coverage of the satellite antenna, while in terrestrial system it varies based on the distance.
How are satellite communication and terrestrial communication used in wireless communication?
A communication satellite is a microwave repeater station in a space that is used for telecommunication, radio and television signals. A communication satellite
processes the data coming from one earth station and it converts the data into another form and send it to the second earth station
.
What is satellite define satellite communication describe briefly the main advantages offered by satellite communication?
Satellite communication is
the method of transporting information from one place to another using a communication satellite in orbit around the Earth
. … Telephone, radio, television, internet, and military applications use satellite communications.
What are the advantages of using satellite communication?
- Flexibility.
- Ease in putting in new circuits.
- Distances are effortlessly taken care of and expense doesn’t make a difference.
- Broadcasting conceivable outcomes.
- Each and each side of the earth is secured.
- User can control the system.
What are four advantages of artificial satellite?

What is the range of terrestrial communication?
Terrestrial television stations broadcast on television channels with frequencies
between about 52 and 600 MHz
in the VHF and UHF bands.
What is the meaning of terrestrial communication?
A terrestrial communication system,
facilitating audio, video, data, and any other type of communication within a local geographical area
, and with an extremely large number of communication channels being made available simultaneously at a very low cost.
How are microwaves used in terrestrial communication?
Uses. Microwaves are widely used for
point-to-point communications
because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be pointed directly at the receiving antenna.
What are the application of communication satellite?
Communications satellites are used for
television, telephone, radio, internet, and military applications
. As of 1 January 2021, there are 2,224 communications satellites in Earth orbit.
What is the primary use of communication satellites?
What is the primary use of communication satellites? Explanation: The primary use of communication satellites is in
long-distance telephone service
. Satellites greatly simplify long-distance calls not only within countries but also worldwide.
What can be used to communicate with satellites?
Satellites communicate by using
radio waves
to send signals to the antennas on the Earth. The antennas then capture those signals and process the information coming from those signals.
What are the basic concept of satellite communications?
Satellite communications involves four steps:
An uplink Earth station or other ground equipment transmits the desired signal to the satellite
.
The satellite amplifies the incoming signal and changes the frequency
.
The satellite transmits the signal back to Earth
.
What do you mean by communication satellite?
noun.
an artificial earth satellite that facilitates communications
, as radio, television, and telephone transmissions, by means of the reflection or the amplification and retransmission of signals between stations on earth or in space.
What are the pros and cons of satellites?
- Pro: Coverage. …
- Pro: Affordability. …
- Con: Propagation delay. …
- Con: Noise and interference. …
- Con: Slower than broadband or cable. …
- Some final thoughts.
