WLC evacuates the Ethernet header when a parcel originates from the wired side, supplanting it with a 802.11 header and embodying it with LWAPP. At last it is decapsulated and sent to the remote customer. 7. In WLAN, what messages are traded among AP and STA and what are the elements of both?

APs are gadgets that help give a wired system remote usefulness. These are a couple of WLAN MAC messages alongside their essential capacity: Affiliation reaction. The AP sends this message in light of accepting an affiliation demand. Affiliation demand. STA sends this message to AP after confirmation so as to get affiliation. Confirmation.
