  • wavelength

    Wavelength is the distance between identical points (adjacent crests) in the adjacent cycles of a waveform signal propagated in space or along a wire.

  • weighted fair queueing (WFQ)

    Weighted fair queueing (WFQ) is a method of automatically smoothing out the flow of data in packet-switched communication networks by sorting packets to minimize the average latency and prevent exaggerated discrepancies between the transmission efficiency afforded to narrowband versus broadband signals.

  • well-known port numbers

    The well-known port numbers are the port numbers that are reserved for assignment by the Internet Corporation for Assigned Names and Numbers (ICANN) for use by the application end points that communicate using the Internet's Transmission Control Protocol (TCP) or the User Datagram Protocol (UDP).

  • white box switch

  • wideband audio (HD voice)

    Wideband audio, also known as HD voice, is a cellular technology that utilizes a wider frequency spectrum to achieve greater voice quality during phone calls.

  • wire speed

    Wire speed refers to the rate of data transfer a given telecommunication technology provides at the physical wire level.

  • wireless mesh network (WMN)

    A wireless mesh network (WMN) is a mesh network created through the connection of wireless access point (WAP) nodes installed at each network user's locale.

  • wrap plug

    A wrap plug, also known as a loopback plug, is a special plug that can be inserted into a port on a communications device to perform a diagnostic test called a loopback test.
