MICROWAVE:  

Microwave are electromagnetic waves whose frequencies range from 1GHz to 1000GHz. for comparison,the signal from an AM radio station is 1 MHz and the signal from FM radio station is 100MHz.

microwave oven

microwave are also called since they are define in terms of their wavelength in the sense that micro refers to tinyness- tinyness referring to wavelength and the period of a cycle of a cm wave.

ADVANTAGE OF MICROWAVES

1.Increased bandwidth availability

 Microwaves have large band widths(1GHz-103 GHz) compared to the common bands namely MW,SW and UHF waves. the advantage of large bandwidths is that the frequency range of information channels will be a small percentage of the carrier frequency and more information can be transmitter in microwave frequency ranges. /microwave region is very useful since the lower band of frequency is already crowded.

2.Fading effect and reliability

Fading effect due to variation in the transmission medium is more efficient at low frequency. Due
to "Line of Sight"(LOS) propagation and high frequencies there is less fading effect and hence microwave communication is more reliable..

3.Power requirements

Transmitter/Receiver power requirements are pretty low at microwave frequencies compared to that at short wave band.
