The overview of Wi-Fi gives you a general outline of the definition and the function of Wi-Fi technology. Wi-Fi is a brand of wireless technology which uses high frequency radio signals to convey and receive data over distances of a few hundred feet using Ethernet protocol. The Wi-Fi wireless technology serves to improve the interoperability of wireless local area network products based on the IEEE 802.11 standards. The Wi-Fi technology has its applications in devices such as Internet, gaming, and network connectivity for consumer electronics like televisions, DVD players as well as digital cameras.

In Wi-Fi enabled device the wireless adapter of a computer translates data into a radio signal and transmits it through an antenna. Then a wireless router gets the signal and decodes it and transmits the information to the Internet using an Ethernet connection.
The Wi-Fi technology is a brand owned by the Wi-Fi Alliance which is a group of separate and independent companies. Companies under the Wi-Fi Alliance have jointly agreed to a set of common interoperable products based on the family of IEEE 802.11 standards. In the overview of Wi-Fi we also discuss the different standards used and the products and devices that uses Wi-Fi technology. The products that pass the tests established by the Wi-Fi Alliance are given the Wi-Fi certified logo. Initially, only products using the 802.11b standard could have the Wi-Fi certification logo. Today, Wi-Fi can apply to products that use any 802.11 standard.
The 802.11 specifications of Wi-Fi technology are part of an evolving set of wireless network standards referred to as the 802.11 family. There are other wireless networking standards such as 802.15 used in Wireless Personal Area Networks (WPANs) and 802.16 used in WiMax technology. In the overview of Wi-Fi we analyze the different uses, advantages as well as disadvantages of Wi-Fi technology. This technology has attained approval in several businesses, schools, agencies, hotels and homes as a substitute to a wired LAN. Today a number of public areas such as airports, hotels, and restaurants offer access to Wi-Fi networks.
The locations which are provided with Wi-Fi network system are referred to as ‘hot spots’ and an interconnected area of hot spots and Wi-Fi access points is called ‘hot zone’. There are many Wi-Fi uses in a number of devises such as game console, cell phone, MP3 player, PC or a PDA. Many more functions and applications of Wi-Fi are being established.
