 === Encapsulation ===
 When an AP encapsulates a packet, it treats the destination address in that Ethernet frame as the receiver address (addr1) in the outgoing wireless MPDU. The source address of the Ethernet frame, however, is not the transmitter address (addr2) of the outgoing wireless MPDU -- the TA address must be the wireless MAC address (or BSSID) of the AP. Instead, the source address of the Ethernet frame is put into the third address location of the outgoing 802.11 header.

 === De-encapsulation ===
+De-encapsulation at the AP recognizes that a station must include the BSSID of the AP as the first argument of the 802.11 header. This receiver address (addr1) is not the destination address of the Ethernet frame. Instead, the destination address is included in the third address location (addr3) of the incoming 802.11 header. The transmitter address (addr2) is the source address of the Ethernet frame that should be generated.
