What Is Satellite Transmission Media
Here is a.
What is satellite transmission media. Popular bound transmission media in use are twisted pair cable co axial cable and fiber optical cable each of them has its own characteristics like transmission speed effect of noise physical appearance cost etc. The services provided by satellite communications are voice and video calling internet fax television and radio channels. This makes system very complex. They are not guided or bound to a channel to follow.
Transmission media then looking at analysis of using them unguided transmission media is data signals that flow through the air. It is also referred to as wired or bounded transmission media. An unguided transmission transmits the electromagnetic waves without using any physical medium. A communications satellite is an artificial satellite that relays and amplifies radio telecommunications signals via a transponder.
Satellite communications is the use of satellite technology in the field of communications. In unguided media air is the media through which the electromagnetic energy can flow easily. Line of sight transmission is used to medium range radio transmission such as cell phones cordless phones walkie talkies wireless networks fm radio and television broadcasting and radar and satellite communication such as satellite television. Bound transmission media are the cables that are tangible or have physical existence and are limited by the physical geography.
Line of sight transmission on the surface of the earth is limited to the distance to the visual. A typical satellite link involves the transmission or uplinking of a signal from an earth station to a satellite. Satellite communications can provide communication capabilities spanning long distances and can operate under circumstances or. In data communication terminology a transmission medium is a physical path between the transmitter and the receiver i e it is the channel through which data is sent from one place to another.
It creates a communication channel between a source transmitter and a receiver at different locations on earth communications satellites are used for television telephone radio internet and military applications. There are about 2 000 communications satellites. The ground segment which consists of fixed or mobile transmission reception and ancillary equipment and the space segment which primarily is the satellite itself. Therefore it is also known as wireless transmission.
Moreover satellite visibility from earth is for very short duration which requires fast satellite to satellite handover. Transmission media is broadly classified into the following types. In order to understand advantages of satellite communication and disadvantages of satellite communication one has to understand satellite communication basics. Wired or guided media or bound transmission media.
They are coaxial cable twisted pair satellite fiber optics microwave thus this is all about transmission media and there are some factors that are considered when choosing a transmission medium like rate of transmission cost simple installation and distances. Radio transmission microwave satellite communication.
