Understanding Wi-Fi and How it Works - lifewire.com

Wi-Fi is commonly mistaken as an acronym for wireless fidelity when in fact, it's not an acronym at all. It's also sometimes spelled as wifi, Wifi, WIFI or WiFi, but none of these are officially approved by the Wi-Fi Alliance. Wi-Fi is also used synonymously with the word "wireless," but wireless is actually much broader.
