- Wideband
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'scoherence bandwidth .Some communication links have such a high data rate that they are forced to use a wideband bandwidth; others links may have relatively low data rates, but deliberately use a wider bandwidth than "necessary" for that data rate in order to gain other advantages; see "spread spectrum ".A wideband antenna is one with 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.
