Before the AP identifies STAs:
1)   The AP does not respond to proberequests from the 2.4 GHz band
2)   but responds to probe requestsfrom the 5 GHz band.
After the AP identifies STAs:
(1) Single-band 2.4 GHz STAs: TheAP sends a response after receiving multiple probe requests and only ensuresthat STAs can access it.
(2) Single-band 5 GHz STAs: TheAP sends a response after receiving a probe request and ensures that STAs canaccess it.
(3) Dual-band STAs: The APresponds to probe requests from the 5 GHz band but does not respond to proberequests from the 2.4 GHz band. The AP leads STAs to access the 5 GHz WLAN. TheAP sends one response after receiving multiple authentication requests from the2.4 GHz band and only ensures that 2.4 GHz STAs can access it.
