The Origins of RF Signals

Radio frequency signals have been used since the late 19th century, with the first practical application being Marconi’s wireless telegraphy system. RF signals are electromagnetic waves that oscillate at frequencies between 3 kHz and 300 GHz.

They are used in various applications such as radio broadcasting, television, radar, GPS, and wireless communication. RF signals have revolutionized the way we communicate and interact with technology.
