What does "Wi-Fi" stand for?

The term Wi-Fi is often mistakenly believed to stand for Wireless Fidelity, but this is not the case. Wi-Fi is not an acronym; it is simply a brand name. The story behind the name began in the late 1990s when the IEEE released the 802.11 standard for wireless networking in 1997, followed by the 802.11b revision in 1999, which offered speeds up to 11 Mbps on the 2.4 GHz band.

The technology worked well, but consumers were unlikely to seek out IEEE 802.11b compatibility at retail stores. To make the technology more memorable for customers, the Wireless Ethernet Compatibility Alliance (WECA) was tasked with finding a suitable name. In 1999, WECA hired branding agency Interbrand, known for creating catchy commercial names like Prozac, Nintendo Wii, and Compaq.

Interbrand came up with a shortlist of ten candidates and selected Wi-Fi, a clever play on the term Hi-Fi, which long denoted high-fidelity audio. The name was chosen for its association with quality and ease of use, without providing any technical details. Interbrand also designed a yin-yang style logo to accompany the name. However, confusion arose over the years, as some alliance board members worried that a name without meaning might confuse customers.

To address this, a tagline, "The Standard for Wireless Fidelity," was attached to the Wi-Fi name. According to Phil Belanger, a founding member of the alliance, the tagline was used for about a year but was later deemed a mistake that diluted the brand's impact. Belanger bluntly stated that Wi-Fi does not stand for anything, and the tagline was subsequently dropped.

Despite this, the misconception that Wi-Fi stands for Wireless Fidelity persists as one of the most common false backronyms in the tech industry.
