Wi-Fi stands for what?

Answer 1

"WiFi" is often thought to stand for "Wireless Fidelity," it is actually a trademarked term that does not stand for anything specific. The term was coined by the Wi-Fi Alliance as a brand name for products that adhere to the IEEE 802.11 standard for wireless local area networks (WLANs).
