Electromagnetic waves at the frequency range of about 2 to 40 GHz are referred to as microwave . Microwave radio operates in unlicensed bands are 2.4 GHz and 5.7 GHz and are licensed band it could operate like 6GHz, 7 GHz, 8GHz, 10GHz, 11GHz and 13GHz, 15GHz, 18GHz and 23GHz, 38GHz frequency bands. At these frequencies, highly directional beams are possible and microwave is quite suitable for point-to-point transmission. Concentrating all the energy into a small beam using a parabolic antenna (like the familiar satellite TV dish) gives a much higher signal to noise ratio, but the transmitting and receiving antennas must be accurately aligned with each other. It’s a type of unbounded network transmission medium. Microwave is mainly used for satellite communications .
A microwave system includes an antenna, radio, multiplexes, waveguide (hollow metal conductor connecting the RF equipment to the antenna) and feed cables. Based on capacity and radio equipment, antenna size, tower heights and terrain elevation will play a major role in how it will planned and construct the system. These four factors also will dictate system reliability, multi-path fading, fade margin calculations, freshnel zone clearance, interference analysis, system diversity and long-distance specifications.
