Microwave In Information Technology

Microwave links are are widely used for point to point communications because their small wavelength allows conveniently sized antennas to direct them in narrow beams which can be pointed directly at the receiving antenna.

Microwave in information technology.

Microwave signals propagate in straight lines and are affected very little by the troposphere. Radar and satellite communication motivated the development of modern microwave antennas. Microwave spectrum is divided into different channels as per application. Today s household microwave ovens consist of an electronic device called a cavity magnetron which produces microwave energy a waveguide that guides the energy in the right direction and a metal enclosure which traps that energy until absorbed by food or another material.

Microwave technology helps to manage crowded spectrum with the use of high selective receivers modulation ssb psk qam etc and spread spectrum techniques data compression etc. Microwave transmitters and receivers are parabolic dish antennas. The parabolic antenna the most common type cassegrain antenna lens antenna slot antenna and phased array. A microwave link is a communications system that uses a beam of radio waves in the microwave frequency range to transmit information between two fixed locations on the earth.

Microwave is a line of sight wireless communication technology that uses high frequency beams of radio waves to provide high speed wireless connections that can send and receive voice video and data information. A microwave oven colloquially referred to as a microwave is an electric oven that heats and cooks food by exposing it to electromagnetic radiation in the microwave frequency range. They produce although microwaves were first produced and studied in 1886 by hertz their practical application had to await the invention of suitable generators such as the klystron and magnetron. They are crucial to many forms of communication and impact a broad range of industries.

Microwave radar became the central technology used in air traffic control maritime navigation anti aircraft defense ballistic missile detection and later many other uses. Microwave technology is used in the world s data tv telegraphs satellites spacecraft communication it is also used in the microwave ovens and in radar technology and shorter microwaves are used in remote sensing. The microwaves are made by various types of transmitter and they are high frequency radio waves we use them.
