Etymology of Wi-Fi

  • Wi-Fi is a technology that connects to wireless networks.

    It is sometimes said that this word is derived from wireless fidelity, but this story is wrong.

    Actually, Wi-Fi is derived from Hi-Fi (High Fidelity : this means audio devices), and “Wi” didn’t have any meaning.

    It is just rhymed.

    The meaning “wireless fidelity” was given later.
