Radio Frequency
Radio Frequency (RF) is also known as radio waves. It is an electromagnetic energy which consists of electrical waves and magnetic energy radiating through space. The areas consisting of the these waves is known as electromagnetic field. They are crested by moving electrical charges in antennas. The electromagnetic waves are measured by the distance covered by one cycle of the wave (wavelength) or the number of waves that pass a certain point in one second (frequency). The frequency of an RF signal is measured in hertz (Hz)
