80211-based, or 802.11-based, describes devices, networks, and systems that implement the IEEE 802.11 family of wireless local area network (WLAN) standards. This designation emphasizes conformity with the standardized air-interface and protocol stack used for Wi-Fi, enabling interoperability across equipment from different vendors. In practice, an 802.11-based network supports wireless connectivity between access points and client devices using common Wi-Fi technologies.

Overview of the family: The original 802.11 standard released in 1997 defined modest data rates for 2.4 GHz. Since then, amendments such as 802.11a/b/g/n/ac/ax/be have introduced higher speeds, improved spectral efficiency, multiple bands, and new features like MIMO and OFDMA in later generations. Today, 802.11-based networks commonly operate in 2.4 GHz and 5 GHz bands, with 6 GHz used by newer 6 GHz‑enabled devices (Wi-Fi 6E/7).

Typical deployment: consumer routers, business access points, and public hotspots form an 802.11-based WLAN. Interoperability is supported through Wi‑Fi Alliance certification and adherence to security protocols such as WPA2 and WPA3, employing encryption with AES and robust authentication methods. Network management includes SSIDs, roaming, and security configurations.

Relation to Wi‑Fi: In common usage, "Wi‑Fi" is the brand name for consumer-grade 802.11‑based wireless networking. The term "80211-based" is a technical description that underlines standard compliance and device interoperability beyond branding.
