narrowband
Tight frequency range
Narrowband describes communication signals or systems that use a limited range of frequencies.
The term is relative—what counts as narrowband depends on context.
In radio, narrowband channels minimize interference but carry less data.
In internet access, narrowband refers to slow connections like dial-up, as opposed to broadband: We're stuck with narrowband out here in the country.
