Glossary definition of Frequency Band

Also known as: Band

Band (Frequency Band) is a term used in telecommunications to refer to a range of frequencies authorised for specific purposes. Each band will be a continuous spectrum of frequencies, with upper and lower limits, and international use of these bands is regulated by the International Telecommunication Union (ITU) to prevent interference.

For example, the medium wave band is approved for several purposes, the most well-known being its use for public service AM (Amplitude Modulation) radio broadcasts.
