Wi-Fi (Wireless Fidelity) - Description
Wi-fi is a wireless data networking protocol, which allows for
PCs and laptops to access the internet, within a given area or
"hotspot", via a high frequency wireless local area network
(WLAN). The term Wi-Fi was coined by the Wireless Ethernet
Compatibility Alliance (WECA) as another name for IEEE 802.11b
networking standard. WECA is still involved in certifying new
wireless modems in order to verify that they are fully
compatible with the standard.
