What is a specific range of frequencies allocated for a particular use called?

A specific range of frequencies allocated for a particular use is referred to as a frequency band. This term implies an intentional designation of a segment of the frequency spectrum for specific types of communication or services, such as amateur radio operations, broadcasting, or telecommunications.

For instance, amateur radio frequencies are segmented into various bands, each assigned to different amateur radio operations that may have unique rules and guidelines. This allocation helps to manage interference and ensure efficient use of the spectrum.

The other terms do have related meanings but do not accurately describe the allocated range of frequencies in the same specific context. Bandwidth generally refers to the width of a frequency band, indicating the difference between the highest and lowest frequencies in that band. Channel represents a specific frequency or specific range used for communication, particularly in systems where multiple signals share the same medium. Signal range can refer to the distance over which a signal can be effectively transmitted, rather than a specific allocation of frequencies.
