Background technique

At present, mainstream access points (access points, APs) all support dual-band wireless Internet access (Wi-Fi), that is, 2.4GHz and 5GHz frequency bands, and more and more wireless terminals such as mobile phones (also called workstations (station, STA)) ) also supports the 2.4GHz and 5GHz frequency bands. For APs, different frequency bands correspond to different service set identifiers (SSIDs), belong to different networks, and have their own authentication access passwords.
