In communications, wideband is a relative term used to describe a wide range of frequencies in a spectrum. A system is typically described as wideband if the message bandwidth significantly exceeds the channel's coherence bandwidth. // An oxygen sensor is an electronic device that measures the proportion of oxygen (O2) in the gas or liquid being analyzed. ...

In most modern usages of the word spectrum, there is a unifying theme of between extremes at either end. ... Definition: Coherence bandwidth is a statistical measure of the range of frequencies over which the channel can be considered flat, or in other words the approximate maximum bandwidth or frequency interval over which two frequencies of a signal are likely to experience comparable or correlated amplitude fading. ...

A wideband antenna is one with the approximately or exactly the same operating characteristics over a very wide passband. Distinguished from broadband antennas, where the passband is large, but the gain and or pattern need not stay the same over the passband.

Wideband in speech services means that the used speech frequency response covers 50-7000 Hz. The opposite of wideband is narrowband. This article is about the SI unit of frequency. ... Narrowband (narrow bandwidth) refers to a signal which occupies only a small amount of space on the radio spectrum -- the opposite of broadband or wideband. ...
