The Meaning of 'Wi-Fi'

Has anybody ever wondered what Wi-Fi means? I have, though I never got a satisfactory answer to it and I still have no idea why it's called Wi-Fi. 

Actually, I kind of thought the "Wi" part stood for wireless since it is a wireless connection but I couldn't wrap my head around the "Fi" part and what it could be in relation to the whole term.

It turns out, it doesn't mean anything. It's all a bunch of marketing hokum.

Wi-Fi Alliance founding member Phil Belanger shared the history of the term with Boing Boing back in 2005. It seems the wireless industry was seeking a user-friendly name to refer to technology that adhered to standards known as IEEE 802.11.
“We needed something that was a little catchier than ‘IEEE 802.11b Direct Sequence,’” he explained. The Wi-Fi Alliance hired Interbrand to come up with ideas, and the brand consultancy proposed 10 names, including Wi-Fi (which sounds lot like “hi-fi,” AKA “high fidelity”).

That is just wrong. Hi-Fi is indeed a shortened version of High Fidelity. Wi-Fi is for Wireless Fidelity. The first encryption for wi-fi was WEP: WIred Equivalent of Privacy, an attempt to give wireless communications the same privacy as a network cable.
The current standard is WPA: Wi-Fi Protected Access which is an acronym made, in part, from an abbreviation which in turn was created to sound like a marketing term (Hi-Fi) from a time before stereo for a technology (vinyl records) that died before many of us were alive.
