    en.wikipedia.org/wiki/Oxygen_sensor

    UEGO sensors are also commonly used in aftermarket dyno tuning and high-performance driver air–fuel display equipment. The wideband zirconia sensor is used in stratified fuel injection systems and can now also be used in diesel engines to satisfy the upcoming EURO and ULEV emission limits. Wideband sensors have three elements: ion oxygen pump,

  3. Ultra-wideband - Wikipedia

    en.wikipedia.org/wiki/Ultra-wideband

    Ultra-wideband is a technology for transmitting information across a wide bandwidth (>500 MHz).This allows for the transmission of a large amount of signal energy without interfering with conventional narrowband and carrier wave transmission in the same frequency band.

    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. The following is a list of devices that support the technology from various UWB silicon providers.

    en.wikipedia.org/wiki/UWB_ranging

    Ultra-wideband impulse radio ranging (or UWB-IR ranging) is a wireless positioning technology based on IEEE 802.15.4z standard, [1] which is a wireless communication protocol introduced by IEEE, for systems operating in unlicensed spectrum, equipped with extremely large bandwidth transceivers.

  8. Spread spectrum - Wikipedia

    en.wikipedia.org/wiki/Spread_spectrum

    Spread spectrum generally makes use of a sequential noise-like signal structure to spread the normally narrowband information signal over a relatively wideband (radio) band of frequencies. The receiver correlates the received signals to retrieve the original information signal.

  9. Wide-bandgap semiconductor - Wikipedia

    en.wikipedia.org/wiki/Wide-bandgap_semiconductor

    Wide-bandgap semiconductors (also known as WBG semiconductors or WBGSs) are semiconductor materials which have a larger band gap than conventional semiconductors. Conventional semiconductors like silicon and selenium have a bandgap in the range of 0.7 – 1.5 electronvolt (eV), whereas wide-bandgap materials have bandgaps in the range above 2 eV.
