ANQP (Access Network Query Protocol)
E513256
ANQP (Access Network Query Protocol) is a network protocol that allows Wi‑Fi clients to query access points for detailed information about available networks and services before associating, enabling seamless and informed network selection in systems like Hotspot 2.0.
