Yes.
it has a narrow band.
Narrow-Band (also referred to as short-wave) is a term used to describe the amplitude of a radio device. Narrow-band devices are limited to an average of 400m.

Narrow-band semiconductor refers to the semiconductor materials with band gap that is relatively smaller than silicon. This is commonly used as thermo-electric or infrared detectors.
A narrow-band semiconductor is a type of semiconductor material with a small energy gap between its valence band and conduction band. This small energy gap allows for electrons to move easily between the bands, making it suitable for applications such as optoelectronics and telecommunications.
central freqency of narrow band pass filter is the measure of difference between upper and lower cut off freqency
If the modulation index of FM is kept under 1, then the FM produced is regarded as narrow band FM. Lower the modulation index, lower the no. of significant sidebands are produced (with reference to bessel function). So lower the no. of significant sideband, lowerer will be the bandwidth of the resulting FM prduced. Sometimes, Narrow Band FM is regarded as, when the significant energy in FM occupies the same bandwidth as ordinary AM with the same modulating signal.
A bandeau is a band worn in the hair, or a variety of strapless bra or top made from a narrow band of fabric.
