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. 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.

The term Wideband Audio or (also termed HD Voice or Wideband Voice) denotes a telephone conversation using a wideband codec, which uses a greater frequency range of the audio spectrum than conventional telephone calls, resulting in a clearer sound.

According to the United States Patent and Trademark Office, WIDEBAND is a registered trademark [1] of WideBand Corporation, a USA based manufacturer of Gigabit Ethernet managed switches, adapters, and networking equipment. [2]
