What is the Full Form of RF?

The full form of RF is Radio Frequency. The radio frequency (RF) measurement represents the oscillation rate of electromagnetic radiation, or electromagnetic radio waves, with frequencies ranging from 300 gigahertz (GHz) to as low as 9 kilohertz (kHz). Using transmitters and antennas, an RF field can be used for a number of wireless broadcasting and communication applications.

RF Technology

RF fields are used by many different types of wireless devices. The RF spectrum is used by radio and television broadcast stations, cordless phones and smartphones, satellite communications systems, Wi-Fi and Bluetooth, and two-way radios. In addition, equipment other than communications, such as microwave ovens and garage door openers, use radio frequencies. Some wireless gadgets, such as computer keyboards, television remote controls, and computer mouse, use infrared frequencies, which have shorter electromagnetic wavelengths.

How Does RF Work?

Radiofrequency is measured in Hertz (Hz) units. These are the number of cycles per second that occur during radio wave transmission. One hertz equals one cycle per second; radio wave cycles per second range from thousands (kilohertz) to millions (megahertz) to billions (gigahertz). A radio wave’s wavelength is inversely proportional to its frequency. Radio waves are invisible to the human eye. As the frequency expands beyond the RF spectrum, electromagnetic energy takes the form of visible, microwaves, ultraviolet, infrared radiation (IR), X-rays, and gamma rays.
