WIFI

Wi-Fi is the name of a popular wireless networking technology that uses radio waves to provide wireless high-speed Internet and network connections. 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 phrase that means IEEE 802.11x .
The Wi-Fi Alliance

The Wi-Fi Alliance , the organization that owns the Wi-Fi registered trademark term specifically defines Wi-Fi as any " wireless
local area network ( WLAN) products that are based on the Institute of Electrical and Electronics Engineers' ( IEEE) 802.11 standards. "
Initially, Wi-Fi was used in place of only the 2.4GHz 802.11b standard, however the Wi-Fi
Alliance has expanded the generic use of the Wi-Fi term to include any type of network or
WLAN product based on any of the 802.11 standards , including 802.11b , 802.11a , dual- band, and so on, in an attempt to stop
confusion about wireless LAN interoperability
