MICROWAVES IN CELLULAR COMMUNICATION
Microwaves argon efficiently apply in the cellular communication. The microwaves are wonderful boon for the wireless communication. The microwaves are introduced in cellular mobile communication at the BTS (Base Transceiver Station) level. The variant BTS under a BSC( Base Station Controller) are coupled to each early(a) with the microwave links irrespective of the engine room we are using. First of all lets get some experience ab break through microwaves themselves:
MICROWAVES
Microwaves are so called since they are defined in terms of their wavelength in the sense that micro refers to diminutiveness and tininess refers to wavelength and period of a cycle of the centimeter wave. In other words the wavelength of the cm waves at microwave frequencies is very delicate typically from a few tens of cm to a figure of a mm.
In short the microwave is a type that has wavelength if 1 foot or less than or just about equal to 1 foot. This converts to a frequency of 984 Mhz = 1 gigacycle per second (approx.). All the frequencies above 1000Mhz (1 Ghz) about 1000 Ghz are microwave frequencies.
HISTORY
James Clerk Maxwell (1831-1879) interconnected all previus known results observational and the theoretical on electromagnetic wavesin four equations and predicted the existence of the electromagnetic waves.
Heinrich Rudolf Hertz (1857-1937) experimentally substantiate Maxwells predictions
Guglielmo Marconi (1874-1937) transmitted information in an experimental basis at microwave frequencies. Goerge C . Southworth (1980) really carried out Marconis experiments on a commercial basis.
During world struggle II (1945) based on the previous developments radar was invented nd exploited for the military purposes
Then people showed keen stakes in investigating how devices could operate in the microwave bands with greathearted powers.
A.W Hull developed the very popular magnetron device who used a magnetic field to influence the flow of electrons.Randoll and Boots raise developed the magnetron in 1939.
