BandIn radio communications, a band is a small spectrum of frequencies, usually used for the same purpose, such as the aircraft band (108~136MHz), FM broadcast band (88~108MHz), upper VHF TV band (174~216MHz in the Americas), and the L band (1452~1492MHz) for digital radio (DAB) outside the U.S
A band is a strip of material in a loop, used for binding. Types of bands:
- rubber band
In a similar sense, a band can also refer to a group of people who are bound together by a common cause, especially if it is one not officially sanctioned by authority. eg. 'band' of pirates or brigands, 'band' of rebels, 'robber band'.
