Wi-Fi (pronunciation:/? wa？ Law? /,French pronunciation: /wifi/), also called "action hotspot" in Chinese, is the trademark of the manufacturer of Wi-Fi alliance as a product brand certification, and is a wireless LAN technology created in the IEEE 802. 1 1 standard. Based on the close relationship between the two systems, Wi-Fi is often regarded as synonymous with IEEE 802. 1 1 standard. "Wi-Fi" is often written as "Wifi" or "WiFi", but they are not recognized by the Wi-Fi alliance.
Not every product that conforms to IEEE 802. 1 1 has applied for the certification of the Wi-Fi Alliance, and the relative lack of Wi-Fi certification does not necessarily mean that it is incompatible with Wi-Fi devices.
The devices of IEEE 802. 1 1 have been installed in many products on the market, such as personal computers, game machines, MP3 players, smart phones, tablet computers, printers, notebook computers and other peripheral devices with wireless Internet access.
Wi-Fi Alliance was founded in 1999, and its name was WECA. In June 2002, it was officially renamed as Wi-Fi Alliance.
