Spectrum

In aviation, spectrum refers to the range of radio frequencies used for communication and navigation purposes. The aviation spectrum is divided into different frequency bands, each with its own specific use. These bands include the VHF (Very High Frequency) band, which is used for air traffic control communication, the UHF (Ultra High Frequency) band, which is used for military communication, and the HF (High Frequency) band, which is used for long-range communication and navigation. The allocation and use of spectrum is regulated by national and international organizations to ensure that there is no interference between different users and to maximize the efficient use of the available spectrum.
