The radio frequency spectrum is the range of electromagnetic waves with frequencies in the radio frequency range. This range of frequencies is typically used for radio communication, television broadcasting, radar, and various other applications. The spectrum is a finite resource, and its allocation and management are crucial for ensuring efficient and interference-free use.

The radio frequency spectrum is divided into different bands, each with specific characteristics and assigned uses. These bands are defined by their frequency ranges, measured in Hertz (Hz). For example, very low frequency (VLF) waves are used for submarine communication, while extremely high frequency (EHF) waves are used for satellite communication and advanced radar systems.

International bodies, such as the International Telecommunication Union (ITU), play a vital role in coordinating the use of the radio spectrum globally. National regulatory authorities, like the Federal Communications Commission (FCC) in the United States, manage spectrum allocation within their respective countries. This management involves licensing specific frequency bands to different users, such as broadcasters, mobile network operators, and government agencies, to prevent interference and ensure orderly operation. The efficient use and management of the radio spectrum are essential for modern telecommunications and many other technologies.
