  2. Wideband - Wikipedia

    en.wikipedia.org/wiki/Wideband

    The term Wideband Audio or (also termed HD Voice or Wideband Voice) denotes a telephony using a wideband codec, which uses a greater frequency range of the audio spectrum than conventional voiceband telephone calls, resulting in a clearer sound. Wideband in this context is usually considered to cover frequencies in the range of 50–7,000 Hz ...

  3. Broadband - Wikipedia

    en.wikipedia.org/wiki/Broadband

    In telecommunications, broadband or high speed is the wide-bandwidth data transmission that exploits signals at a wide spread of frequencies or several different simultaneous frequencies, and is used in fast Internet access. The transmission medium can be coaxial cable, optical fiber, wireless Internet , twisted pair cable, or satellite.

  4. Wide area network - Wikipedia

    en.wikipedia.org/wiki/Wide_area_network

    The textbook definition of a WAN is a computer network spanning regions, countries, or even the world. [3] [4] However, in terms of the application of communication protocols and concepts, it may be best to view WANs as computer networking technologies used to transmit data over long distances, and between different networks.

  5. Bandwidth (signal processing) - Wikipedia

    en.wikipedia.org/wiki/Bandwidth_(signal_processing)

    the width of the range of some other phenomenon, e.g., a reflection, the phase matching of a nonlinear process, or some resonance; the maximum modulation frequency (or range of modulation frequencies) of an optical modulator; the range of frequencies in which some measurement apparatus (e.g., a power meter) can operate

  6. Radio spectrum - Wikipedia

    en.wikipedia.org/wiki/Radio_spectrum

    A wide range of personal radio services exist around the world, usually emphasizing short-range communication between individuals or for small businesses, simplified license requirements or in some countries covered by a class license, and usually FM transceivers using around 1 watt or less.

  7. Ultra-wideband - Wikipedia

    en.wikipedia.org/wiki/Ultra-wideband

    Ultra-wideband (UWB, ultra wideband, ultra-wide band and ultraband) is a radio technology that can use a very low energy level for short-range, high-bandwidth communications over a large portion of the radio spectrum. [1] UWB has traditional applications in non-cooperative radar imaging.

  8. Dynamic range - Wikipedia

    en.wikipedia.org/wiki/Dynamic_range

    Audio engineers use dynamic range to describe the ratio of the amplitude of the loudest possible undistorted signal to the noise floor, say of a microphone or loudspeaker. [18] Dynamic range is therefore the signal-to-noise ratio (SNR) for the case where the signal is the loudest possible for the system. For example, if the ceiling of a device ...
