= Ethernet Encapsulation and De-encapsulation =

Ethernet encapsulation describes the process by which an 802.11 MPDU wraps a full Ethernet frame for transmission while Ethernet de-encapsulation describes the reverse. The 802.11-2012 standard describes this process in Annex P, "the Integration Function." The process is slightly different depending whether the device performing the action is an access point or station.

The above figure shows how an AP encapsulates and de-encapsulates different types of Ethernet frames.
