Wi-Fi (pronounced as /wafa/, pronounced as /wifi/ in French), also known as "action hotspot" in Chinese, is a trademark of the manufacturer of the Wi-Fi alliance as a product brand certification, and is a wireless LAN technology created in the IEEE802. 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.
