WiFi (might stand for Wireless Fidelity) is a general wireless standard/term governed/coined by Wi-Fi Alliance.
The Alliance uses this term to describe many wireless specific technologies like WLAN( IEEE 802.11), PAN and may be WiFi direct and similar technologies.
 
Wi-Fi stands for Wireless fidelity, it is a gendral term used to call 802.11a/b/g.
WLAN stands for all 802.11 stands, it includes a/b/g/d/h/j/i.
 
But no one told the difference.... the fullform of the words never makes the difference.....

WIFI -is a service & WLAN - is application which uses the wifi/wimax service
just as Wireless lan is incomplete without internet ...subscribe either for wifi/wimax or wired Internet ie:broadband

WLAN is a Group of Computers Connected wirelessly, One more of Wireless lan is Peer to peer , ie connection of 2 computers with out a physical media,and next is infrastructure mode where more than 2 computers involved, the latter one is widely used for internet access with a wireless router

Wi-Fi is a trademark of the Wi-Fi Alliance an organization,Wi-Fi is a technology and set of standards that allows for the implementation of WLANs., as this is a Set of standards followed by industry, its easy to use wifi anywhere, ie. its a widely accepted standard....
 
Dear Mr. Sivaram, If a wireless module supports WLAN means, is it supporting to WIFI?

WLAN in general refers to any LAN (Local Area Network) that a user can create/connect to via a wireless/radio connection. IEEE 802.11 is the foremost standard for wireless LANs.

As I stated before WiFi is a trademark coined by Wi-Fi Alliance to brand devices compliant to IEEE 802.11 standards.
There might be a lot of devices which confirm to the IEEE 802.11 standards but are not certified by the Wi-Fi Alliance and hence might not have "WiFi" logo on them.

Simply put, All devices with a "WiFi" logo would support WLAN but the other way around might not be true.
