Wi-Fi Technology
Introduction:
Electrical technology has been greatly enhance with the introduction of wireless communication. Wi-Fi is the one among the achievements. The term Wifi stands for Wireless fidelity.
Wi-Fi is a brand originally licensed by the Wi-Fi Alliance to describe the underlying technology of wireless local area networks (WLAN) based on the IEEE 802.11 specifications. It was developed to be used for mobile computing devices, such as laptops, in LANs, Internet and VoIP phone access, gaming, and basic connectivity of consumer electronics such as televisions and DVD players, or digital cameras and used by cars in highways. A person with a Wi-Fi enabled device such as a computer, cell phone or PDA can connect to the Internet when in proximity of an access point. The region covered by one or several access points is called a hotspot. Hotspots can range from a single room to many square kilometres of overlapping hotspots. Wi-Fi can also be used to create a mesh network and allows connectivity in peer- to- peer mode. Both architectures are used in community networks.

Discovery:
Despite the similarity between the terms 'Wi-Fi' and 'Hi-Fi', statements reportedly made by Phil Belanger of the Wi-Fi Alliance contradict the popular conclusion that 'Wi-Fi' stands for 'Wireless Fidelity. The precursor to Wi-Fi was invented in 1991 by NCR Corporation/AT&T (later Lucent & Agere Systems) in Nieuwegein, the Netherlands. Vic Hayes, who was the primary inventor of Wi-Fi and has been named the ‘father of Wi-Fi,' was involved in designing standards such as IEEE 802.11b, 802.11a and 802.11g.
Types:
Wi-Fi infrastructure devices typically fall into 3 categores as per it’s Application, with wireless being only one of many features.
