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.
