Question

Microwave transmission networks in telecommunication

Answer 1

Microwave transmission is the transmission of information or energy by microwave radio waves. Although an experimental 40-mile (64 km) microwave telecommunication link across the English Channel was demonstrated in 1931, the development of radar in World War II provided the technology for practical exploitation of microwave communication. In the 1950s, large transcontinental microwave relay networks, consisting of chains of repeater stations linked by line-of-sight beams of microwaves were built in Europe and America to relay long distance telephone traffic and television programs between cities. Communication satellites which transferred data between ground stations by microwaves took over much long distance traffic in the 1960s. In recent years, there has been an explosive increase in use of the microwave spectrum by new telecommunication technologies such as wireless networks, and direct-broadcast satellites which broadcast television and radio directly into consumers' homes.

Answer 2

WHAT IS MICROWAVE TRANSMISSION?

Microwave transmission uses a frequency range from 300MHz to 300GHz to carry signals. These waves travel in a straight line and cannot penetrate buildings. These uses big antennas called microwave towers to send and receive data.

ADVANTAGES OF THIS TRANSMISSION

1) These are useful in transmitting data INA difficult terrain.

2) The towers for these waves can be set up at the top of a building.

3) To send and receive microwaves, the transmitting and receiving antennas should be aligned because these waves travel in a straight line.

DISADVANTAGES OF THIS TRANSMISSION

1) The signals sent through microwave are not secure.

2) The cost of setting up microwaves is more than that of the radio waves.

3) These signals are impacted by weather conditions.
