Explanation

Authentication in a WLAN serves to verify and validate that only authorized hosts/devices can connect to and utilize the wireless network. It prevents unauthorized access by checking credentials (passwords, certificates, etc.) before allowing network connectivity. Authentication does not encrypt data (that's encryption), indicate channels (that's channel selection), or allow channel choice (that's client-side behavior). Its primary purpose is access control and identity verification.
