In 802.11 frame, you will see that the 802.11 data frame defines four address fields, named Address 1, Address 2, Address 3, Address 4.
The first step to understanding the addressing scheme of an 802.11 frame is to identify the logical addresses that used.
Source Address: This is the address where the frame is sent from.
Destination Address: This is the address where the frame is being sent to.
Transmitter Address: This is the address of the station that is transmitting the RF frame.
Receiver Address: This is the address of the station that is receiving the RF frame.
Basic Service Set Identifier: This is the basic server set ID of the AP.

As you could see the following picture,
- STA1 must send the frame to AP1.
- AP1 must forward that frame to AP2.
- AP2 must forward that frame to STA2
