Frequency band

Frequency band is a specific range of frequencies in the electromagnetic spectrum. It is typically divided into multiple sub-bands, which are designated by different terms such as ultra high frequency, very high frequency, and super high frequency. These terms are often used in the context of telecommunication, radio broadcasting, and wireless networking technologies.

Etymology[edit | edit source]

The term "frequency band" is derived from the word "frequency", which refers to the number of occurrences of a repeating event per unit of time, and "band", which refers to a range of frequencies.

Description[edit | edit source]

A frequency band is a range of frequencies that is defined by a lower and upper frequency limit. These limits are often defined by regulatory authorities such as the Federal Communications Commission in the United States, or the International Telecommunication Union globally. The specific frequency ranges are allocated for different uses, such as television broadcasting, mobile telephony, or satellite communication.
