multifrequency
Across several bands
Multifrequency describes systems or signals that operate across multiple frequencies simultaneously or in sequence.
The term appears in telecommunications, audio engineering, and scientific instrumentation: multifrequency tonal signaling, a multifrequency sonar array.
Touch-tone phones use multifrequency dialing, where each button produces two tones at once.
