SPECTRUM MANAGEMENT 1
=== Introduction to Radio Frequency Spectrum===
 * -The radio frequency spectrum is a man-made natural resource. It is man-made in the sense that the extent of the

usable spectrum is limited only by man's ability to technologically employ radio frequencies. Otherwise it has the characteristics of a natural resource. The radio frequency

Spectrum is finite and is not exhausted through use nor does it become worn out. As with other natural resources, careless use can pollute it and prevent the extracting of maximum benefit from the spectrum.

The radio frequency spectrum ranges from ten kilohertz (10,000 hertz) to three terahertz (3,000,000,000 hertz). Of this broad expanse of radio frequencies, only about forty gigahertz (40,000,000 hertz) is allocated for radio usage.

Spectrum Management:


-Spectrum Management can be defined as the process of regulating the use of radio frequencies to promote efficient use and gain a net social benefit.In simple words we can say that Radio frequency spectrum management concerns itself with the control of the spectrum resource as a whole.

“The Radio Act of 1927”:
-Prior to 1927, radio was regulated by the United States Department of commerce.Commerce Secretary “Herbert Hoover” played a strong role in shaping radio. His powers were limited by federal court decisions, however; in particular, he was not allowed to deny broadcasting licenses to anyone who wanted one. The result was that many people perceived the airwaves to suffer from "chaos," with too many stations trying to be heard on too few frequencies. Others believed the government simply wanted to control content. (Initially only two frequencies were available for broadcasting with one of these being reserved for "Crop reports andweather forecasts.") After several failed attempts to rectify this situation, Congress finally passed the Radio Act of 1927, which transferred most of the responsibility for radio to a newly created Federal Radio Commission.
