Wi-Fi

Wi-Fi was originally a brand licensed by the Wi-Fi Alliance to describe the embedded technology of wireless local area networks (WLAN) based on the IEEE 802.11 standard. As of 2007, common use of the term Wi-Fi has broadened to describe the generic wireless interface of mobile computing devices, such as laptops in LANs. The term Wi-Fi was chosen as a play on the term "Hi-Fi", and is often thought to be an abbreviation for wireless fidelity, though the Wi-Fi Alliance no longer recognizes such. Wi-Fi and the Wi-Fi CERTIFIED logo are registered trademarks of the Wi-Fi Alliance, the trade organization that tests and certifies equipment compliance with the 802.11x standards.

Common uses for Wi-Fi include Internet and VoIP phone access, gaming, and network connectivity for consumer electronics such as televisions, DVD players, and digital cameras. In spite of media reports about possible health risks from Wi-Fi, scientific studies have failed to show a causal effect.
