Wi‑Fi is based on IEEE 802.11 and is used for local networking and Internet access via wireless routers/access points.
Wi‑Fi is a family of wireless networking protocols based on the IEEE 802.11 standards. It enables nearby digital devices to exchange data over radio waves, and it is widely used for local area networking and Internet access. In homes and small offices, Wi‑Fi connects devices through wireless routers and access points; in public places such as coffee shops, hotels, libraries, and airports, it provides wireless Internet access via hotspots. Wi‑Fi’s purpose is to allow compatible devices to network with each other and with wired networks (including the Internet) using common Wi‑Fi standards. Different Wi‑Fi versions (IEEE 802.11 standards) determine key technical characteristics such as radio bands, channelization, maximum range, and achievable speeds. Wi‑Fi is a trademark of the Wi‑Fi Alliance, which restricts the “Wi‑Fi Certified” label to products that pass interoperability certification testing; non-certified devices may still work but are referred to as WLAN rather than “Wi‑Fi Certified.”
Wi‑Fi is based on IEEE 802.11 and is used for local networking and Internet access via wireless routers/access points.
It allows nearby devices to exchange data over radio waves and to connect to wired networks and the Internet.
Wi‑Fi versions define radio bands, channels, range, and speed; Wi‑Fi commonly uses 2.4 GHz and 5 GHz (and newer generations add 6 GHz).
The Wi‑Fi Alliance controls the “Wi‑Fi Certified” branding through interoperability and security-related certification testing.
A widely used family of wireless networking protocols based on IEEE 802.11 that supports local networking and Internet access over radio waves.
The set of standards on which Wi‑Fi is based, defining how wireless devices communicate and how different versions operate.
A device that connects multiple wireless clients to an adjacent wired LAN, relaying data between wireless devices and the wired network.
A Wi‑Fi coverage area provided by an access point, ranging from a small room to larger outdoor areas using multiple access points.
An organization that manages the Wi‑Fi trademark and certification process to ensure interoperability and backward compatibility among certified products.
A term for wireless local area networking that may include non-certified Wi‑Fi hardware, which may or may not interoperate with “Wi‑Fi Certified” devices.
A 32-byte identifier that names a Wi‑Fi network and is configured on the devices that belong to that network.
