Terrestrial And Satellite Microwave

Microwave radio relay is a technology widely used in the 1950s and 1960s for transmitting signals such as long distance telephone calls and television programs between two terrestrial points on a narrow beam of microwaves.

Terrestrial and satellite microwave. For terrestrial links antennas are located at a specific height to overcome obstacles and also repeaters are to be used in between the links to compensate for path losses. These transmissions are normally made in the spectrum from 2 ghz up to 24 ghz. Satellite or satellite microwave communication provides voice fax data and video services as well as email file transfer www internet applications. In case when the fixed wire terrestrial communication networks are crushed by a disaster then the satellite and microwave system as a emergency backup facility will be stressed.

Satellite microwave transmission system uses satellites for broadcasting and receiving of signals. Both of these systems require transmit part and receive part. Lower power means less weight smaller size and reduced power consumption. Advantages of terrestrial microwave over satellite.

In microwave radio relay microwaves are transmitted on a line of sight path between relay stations using directional antennas forming a fixed radio connection between the. Microwave terrestrial satellite 1. Ground based systems can use a tracking antenna. Microwave terrestrial satellite 2.

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. 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. Terrestrial microwave technologies share with satellite microwave technologies many of the scientific and technical improvements used to accomplish microwave transmissions. Microwave communication systems are mainly classified into satellite systems and terrestrial systems.

Microwave communications are used for short range communications while satellite communications can be established over long distances. The rf link operates over a shorter distance and requires less power than a satellite equivalent. The signals in these systems are extended with the help of relay towers. Satellite microwave transmission system smts.

Terrestrial microwave systems need directional parabolic antennas to broadcast and receive signals in the lower gigahertz range. The satellite costs are independent of distance whereas the terrestrial network costs are proportional to distance. Reduced size weight. This allows for multichannel transmissions and a high bandwidth.
