satellite communication is used for long distance communication, in this signals are transferred from landlines to station , station to satellite and then satellite to station , station to destination.
while bts is used for short distance communication with help of bts towers and range of bts towers lies between 8-15km.

What 's the difference between satellite and terrestrial?
IN COMMUNICATIONS: Satellite uses satellite (orbiting) relay-stations in Space but Terrestrial uses cable or antenna-to-antenna signals based entirely on Earth to broadcast your television, radio or cell-phone :) ++++ IN ASTRONOMY: Terrestrial means Earth- (or planet-) bound; a Satellite is any natural or man-made object that orbits a planet. The Moon is a satellite of the Earth.
What are the most important features of a communication satellite?
To provide communication services between mobile users.
What is radar communication?
Radar communication is electronic communication without the use of wires. Radar communication can be between a ground terminal, like a cell tower, and a satellite. Or it can be between ground towers and also between two or more satellites.
Comparison between conventional cellular radio system and satellite based cellular radio system?
Satellite-based cellular systems In addition to the terrestrial systems, in recent years satellite-based telephone systems have been under construction. With such a system it is possible to make a connection with a cellular phone all around the world, especially in those regions currently not covered by a terrestrial system. In contrast with other satellite communication systems, satellite-based phone systems operate in the Low Earth Orbit (780 km high), and are therefore called LEO systems. The satellites work differently from those at a much higher orbit (36,000 km) in two major ways. First, the small distance between earth and satellite makes it possible to connect to the system with a handheld device. Second, signals can be moved overhead in between satellites without the use of base stations on the earth. In the near future, operators will supply services in which terrestrial and satellite communication are integrated. Like in the terrestrial systems, the satellites operate on certain frequencies, that have to be selected in such a way that interference is avoided. Not only frequencies are needed to communicate with handheld devices, but also to establish communication between satellites and ground stations, and between satellites mutually. cellular telecommunication networks One of the most recent applications of wireless communication is the establishment of fixed cellular telecommunication networks. In contrast to mobile cellular networks, in non-mobile or fixed systems both the transmitters and receivers are located at fixed points in the area. Fixed cellular networks provide a financially attractive alternative to the construction of conventional wired networks in developing countries, where no
Which is the most suitable means of reliable continuous communication between an orbiting satellite and earth?
Microwaves
Why is it important to differentiate between academic and casual communication?
If written, one way to differentiate is to analyse the spelling and grammar. They are of far greater importance academically.The difference between academic and casual communication is academic is talking more about professional knowledge, and casual is very casual.Academic communication is communication you use in a professional manner. Casual communication is a type of communication that you use when socializing with friends and family. Casual could be physical gestures, facial expressions, written, face to face, and/or through the tone of your voice.
How can we differentiate between subjective and objective language in communication?
Subjective language is based on personal opinions, feelings, and beliefs, while objective language is based on facts, evidence, and observations. To differentiate between the two in communication, we can look for words that express personal viewpoints (subjective) versus words that present verifiable information (objective).
What are the common applications of terrestrial microwave?
Terrestrial microwave is commonly used for point-to-point communication between two fixed locations, such as in microwave links for telecommunications networks. It is also used for backhaul connections in wireless communication systems and for broadcasting TV and radio signals. Additionally, terrestrial microwave can be utilized for radar systems in weather forecasting and air traffic control.
Satellite of earth?
A satellite of earth that is not man made is the moon. There are many satellites that are man made that orbit the earth. These satellites are used for communication between Internet and television viewing.
What is the difference between terrestrial and digital television transmission?
Digital television is the opposite to analogue television. There are 3 ways of receiving digital television: 1) Satellite 2) Cable 3) Aerial (terrestrial) Thus using a terrestrial aerial is one method of receiving digital television (branded as Freeview in UK)
How does a Landsat satellite differentiate between objects on Earth's surface?
Features on Earth radiate warmth at different frequencies, which show up as different colors on Landsat images.
What keeps the satellite in orbit Centripetal or electrical?
Centripetal force is what keeps a satellite in orbit around a celestial body, like Earth. This force is due to the gravitational attraction between the satellite and the celestial body. Electrical forces play a role in satellite communication and operation, but they are not directly responsible for keeping the satellite in orbit.
