Terrestrial And Satellite Microwave Transmission

In this system attenuation mainly depends on frequency and signal strength.
Terrestrial and satellite microwave transmission. Microwave communications are used for short range communications while satellite communications can be established over long distances. Microwave terrestrial satellite 1. Microwave communications are ideal for television and radio broadcasts while satellite communications are used for communicating to ships and aircrafts relaying telephone calls and providing communications to remote areas. The frequency range used in this system is between 11 ghz to 14 ghz.
The antenna also has to be directed toward the satellite so that it focuses the parabola on the satellite transmission. Features of satellite microwave. 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. Attenuation is generally affected by the frequency and.
Terrestrial microwave transmission system satellite microwave transmission system. Terrestrial microwave transmission microwave transmission in the atmosphere can only take place when there is a direct line of sight between the sender s and receiver s antenna. Microwave transmission uses very high frequency signals frequency range 300mhz 300ghz wavelengths range in air 100cm 1mm the two types of microwave transmission microwaves are electromagnetic waves microwave terrestrial satellite 1 2 3. These positive elements of terrestrial microwave transmission make up for the expense of constructing the repeater stations every 30 miles and dealing with frequency regulations.
Signals still travel in straight lines in satellite transmission. Microwave terrestrial satellite 2. Satellite transmission is much like the line of sight transmission in which one of the stations is a satellite orbiting the earth. The principle is the same as the terrestrial microwave.
These transmissions are normally made in the spectrum from 2 ghz up to 24 ghz. From oiv s satellite and multimedia centre equipped with 10 satellite transmission stations with dishes ranging from 2 4 to 7 6 m in diameter and over 20 satellite receiver dishes with diameters of 3 7 m and 2 4 m and with automated de icing systems installed we can transmit television and radio programming to any satellite visible from. The frequency range needed is from 4 ghz to 6 ghz. Satellite microwave transmission systems are similar to terrestrial microwave systems except that the signal travels from a ground station on earth to a satellite and back to another ground.
The next higher part of the radio electromagnetic spectrum where the frequencies are. It provides transmission capability to and from any location.
