The radio frequency spectrum refers to the range of electromagnetic frequencies used for transmitting data wirelessly. It spans from very low frequencies, like those used in AM radio, to extremely high frequencies, such as those used in satellite communications. This spectrum is crucial for various technologies, including cellular networks, Wi-Fi, and television broadcasting. Different parts of the radio frequency spectrum are allocated for specific uses to prevent interference between services. Regulatory bodies, like the Federal Communications Commission (FCC) in the United States, manage these allocations to ensure efficient and fair use of the spectrum. This organization helps maintain order in the airwaves, allowing for reliable communication.
