TL;DR
Wi-Fi is not short for "Wireless Fidelity." In 1999, branding agency Interbrand coined it for the IEEE 802.11b standard simply because it rhymed with Hi-Fi. The "Wireless Fidelity" expansion is a backronym added later — it never meant anything.

IEEE 802.11b Was Hard

When the wireless LAN standard IEEE 802.11b was released in 1999, the industry recognized that a more accessible name was needed for general users. The technical designation was cumbersome and difficult to remember. Consequently, the Wi-Fi Alliance, which was then known as WECA, approached Interbrand with a specific request: to devise a name that was "simple, short, and memorable." This initiative aimed to bridge the gap between complex technical specifications and everyday usability, ensuring wider adoption and recognition of the new wireless technology among the public.

Ten Candidates

Interbrand presented a list of ten potential names, from which "Wi-Fi" was ultimately selected. The choice was partly due to its phonetic resemblance to "Hi-Fi," which suggested a concept of "high-quality wireless" without actually being an abbreviation. Crucially, the name "Wi-Fi" was never intended to stand for anything. This was clearly documented in the official meeting minutes, where it was explicitly stated as "not an acronym," clarifying its origin as a coined term rather than an initialism.

The Myth's Beginning

The problem began when the phrase "Wireless Fidelity" started appearing in various marketing materials, erroneously presented as the full form of Wi-Fi. Phil Belanger, who served as chairman of the Wi-Fi Alliance at the time, later issued an official denial. He stated unequivocally that "We did not create that phrase, and it doesn't make sense semantically." Belanger emphasized that the concept of "fidelity" pertains to the accuracy of sound or image reproduction, making its association with wireless communication illogical and incorrect. This widespread misinterpretation persisted despite official refutations.

The Power of a Name

The Chinese character for "name," 名 (myeong), offers insight into its fundamental purpose. It is formed by combining 夕 (seok, meaning evening or dusk), and 口 (gu, meaning mouth), illustrating "something called out by mouth when it's too dark to see." This etymology underscores that a name's primary function is to be spoken and recognized. No matter how advanced or intricate a technology may be, it cannot achieve broad acceptance if its designation is cumbersome or difficult to pronounce. The creation of the name Wi-Fi was a deliberate strategy that perfectly captured this essential principle of human communication and adoption.
