What is Wi-Fi? (Definition & Meaning) | Webopedia

A common misconception is that the term Wi-Fi is short for “wireless fidelity,” however this is not the case. Wi-Fi is simply a trademarked term meaning IEEE 802.11x.

Wi-Fi Definition - What is Wi-Fi?

Short for “Wireless Fidelity.” (Yes, it is pretty much a rip-off of the term “Hi-Fi,” or High Fidelity, which refers to high-quality audio or surround sound.) Wi-Fi refers to wireless network components that are based on one of the Wi-Fi Alliance’s 802.11 standards.

Wireless Fidelity (Wi-Fi)
The popular term for a high-frequency wireless local area network. The consumer-friendly name for the 802.11b engineering standard. It lets home and office users create wireless local networks, which connect two or more computers to each other and a faster Internet line. This way there is no more poking holes in walls or tripping over bulky Ethernet cables. The Wi-Fi technology is rapidly gaining acceptance as an alternative to a wired local area network (LAN)

It’s probably like the suffix “aholic” once applied to alcohol to form alcoholic, instead of just using “ic” they hadd oholic to form the meanings of addictions. Like shopaholic, chocoholic, etc

So the answer to the question is: nothing.
