![]() ![]() This has many implications on how the protocol (including security) works. All stations only have a channel to the switch, and nothing else. This means the AP essentially acts as a wireless switch. The AP will then retransmit (or not) the packet to the destination station, changing only the transceiver and receiver address. This is implemented as follows: if a station wants to communicate with another station, it must send a packet to the AP with the transceiver and source address set to its MAC address, the receiver address set to the AP's MAC address (known as the BSSID) and the destination address set to the intended station's MAC.
