Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves.
The electromagnetic spectrum contains all the frequencies of electromagnetic waves including gamma-rays, ultraviolet, visible, light waves, microwaves, and radio waves. Electromagnetic waves are categorized according to their frequency. Electromagnetic Spectrum starts with Gamma-Rays with starting frequency of 10×15 GHz to radio waves <300 GHz.
Radio frequency (RF) refers to the rate of oscillation of electromagnetic radio waves. Radio waves are in the range of 3 kHz to 300 GHz, This is the frequency band that is used for communications transmission and broadcasting. These frequency bands are divided into different parts, which are then assigned to different technology industries. This is called Radio Spectrum. Although RF really stands for the rate of oscillation of the waves, it is synonymous to the term “radio,” or simply wireless communication.
Radio frequency is produced by oscillating current for a specified number of times (Frequency ) and then radiating it off via a conductor, referred to as an antenna, into empty space (not outer space).
It’s radio transmission technology that’s built upon radio frequency (RF) technology — a frequency within the electromagnetic spectrum between, to allow high-speed and secure communications between a wide variety of digital devices. It makes it possible for Wi-Fi capable devices to access the internet without the need for restrictive wires.
