radio frequency

Radio frequency (RF) refers to the range of electromagnetic waves that can transmit data over distances without wires. It spans frequencies from about 3 kilohertz (kHz) to several hundred gigahertz (GHz). These waves are used in various applications such as radio and television broadcasting, mobile phone communication, and wireless networking. When RF signals are sent through the air, they carry information, like music or phone calls, to receivers that can decode the signals back into usable formats. Essentially, RF enables the wireless communication essential for many modern technologies.
