Ràdiofreqüència

Ràdiofreqüència refers to a range of electromagnetic wave frequencies within the electromagnetic spectrum. Specifically, it typically encompasses frequencies from about 3 kilohertz (kHz) to 300 gigahertz (GHz). This portion of the spectrum is crucial for a wide variety of modern technologies. Radio waves are generated by the oscillation of charged particles, such as electrons, and they can travel through space at the speed of light.

The applications of radio frequency are extensive. It is the fundamental principle behind radio and television broadcasting, enabling the transmission of audio and visual information wirelessly over long distances. Mobile phone communication relies heavily on radio frequencies to establish connections between devices and cellular towers. Wireless networking technologies, such as Wi-Fi and Bluetooth, also operate within specific radio frequency bands. Other uses include radar systems for navigation and detection, microwave ovens for heating food, and various industrial, scientific, and medical applications. Different frequency bands are allocated by regulatory bodies to prevent interference and ensure efficient use of this valuable resource.
