Where does Wi-Fi name come from?
WECA named the new technology Wi-Fi. (Wi-Fi is not an abbreviation for “wireless fidelity”; the name was created by a marketing firm hired by WECA and chosen for its pleasing sound and similarity to “hi-fi” [high-fidelity].) Subsequent IEEE standards for Wi-Fi have been introduced to allow for greater bandwidth.
