Radio frequency (RF) is a measurement representing the oscillation rate of electromagnetic radiation spectrum, or electromagnetic radio waves, from frequencies ranging from 300 GHz to as low as 9 kHz. With the use of antennas and transmitters, an RF field can be used for various types of wireless broadcasting and communications.
The RF part of the spectrum is usually defined as being between 30 kHz and 300 GHz. RF radiation is mainly used in telecommunications. Mobile phones employ frequencies in the range of 800 MHz to 2GHz. Other uses of RF energy include microwave ovens and medical treatments.
