High Quality Content by WIKIPEDIA articles! The radio frequency (RF) spectrum is a conceptual tool used to organize and map the physical phenomena of electromagnetic waves. These waves propagate through space at different frequencies, and the set of all possible frequencies is called the electromagnetic spectrum. The term radio spectrum typically refers to the full frequency range from 3 kHz to 300 GHz that may be used for wireless communication. Most countries consider RF spectrum as an exclusive property of the state. The RF spectrum is a national resource, much like water, land, gas and minerals. Unlike these, however, RF is reusable. The purpose of spectrum management is to mitigate radio spectrum pollution and maximize the benefit of usable radio spectrum.
