Radio Frequency (RF)

Radio Frequency (RF) refers to a range of electromagnetic waves used to transmit signals wirelessly. These frequencies, typically from about 3 kHz to 300 GHz, allow devices like radios, cell phones, Wi-Fi, and broadcasting systems to send and receive data without physical connections. RF signals travel through the air or space and can be modulated to carry information like voice, video, or internet data. The specific frequency determines how the signal behaves, including its range and how much data it can carry. RF technology is essential for modern wireless communication systems.
