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.
Mobile Computing deals with a set of computing methodologies that are required to make a device operational during mobility but, the mobile networking infrastructure and their inter operations comes under the domain of Mobile Communication.
The modern form of communication and result of devepment in communication tools is satellite communication which is creating a buzz all where.It is a direct to home way of broadcasting where the signals are caught by an antenna and decoded by a digital decoder and transmitted out via an output medium like TV in the form of tv channels.The quality of audio-video is subsequently better than cable tv.(digital form)
While terrestrial communication is a primitive way of broadcasting,and involves MOS(multi-service operators) and other cable TV-Operaters.The quality of audio-video is compromised because of the intermidiates between the broadcaster and viewers(analog form).
A satellite phone functions due to satellites which are in outer space orbiting the earth. Cell phones, on the other hand, function due to so-called cell sites on earth. Both types of phones are capable of providing broadband internet access.
Cellular phones use small base stations named "cells". When you move out of range from one cell, another cell takes over. Because of cost and logistics, cell towers aren't placed in extreme rural areas, in the middle of oceans, or in third world countries for the most part. Satellite phones don't rely on cell towers. The signal goes to a low orbiting satellite in the sky, so it will work where normal cell phones wont.
Cell phone use terrestrial sites located on the earth and usually only get reception in a certain are. Satellite phone use orbiting satellites and they usually get reception all around the world.

What 's the difference between satellite and terrestrial?
Satellite communication involves transmitting signals to and from an artificial satellite in orbit around the Earth, while terrestrial communication uses ground-based infrastructure like cables, fiber optics, and antennas. Satellite communication can cover large distances and is often used in remote areas, while terrestrial communication typically offers faster speeds and lower latency for more localized communication.
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.
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.
What is the difference between terrestrial TV and satellite TV?
Terrestrial is earthbound. It is broadcast from antenna towers here on Earth. Satellite TV is broadcast by communications satellites from outer space in geosynchronous orbit. They orbit at the same rate that the Earth rotates, therefore they remain "parked" over the same geographic region, relative to the surface of the Earth they are standing still. Terrestrial TV also makes use of satellites, but rather than broadcasting directly to a customers dish, they are broadcasting specifically for re-broadcast by local network affiliates over their terrestrial antennas.
