Frequency Agile

A term used in the communications industry to signify equipment that can operate on more than one frequency. It sometimes implies that the frequency selection is done automatically by the device. In our industry this term is used to denote wireless systems where the frequency (or channel as it is often called) can be varied by the user. This is an important attribute for touring acts because they need to use different frequencies in different locations due to television stations and other possible interference in a particular area.
