A-MSDU: The concept of A-MSDU is to allow multiple MSDUs to be sent to the same receiver concatenated in a single MPDU. This supporting function for A-MSDU within 802.11n is mandatory at the receiver. Due to Destination Address (DA) and sender Address (SA) in the subframe header must match to same receiver address (RA) and the transmitter Key Takeaway: A-MSDU is transmitted as a single 802.11 frame with multiple 802.3 frames inside it, only having to be sent, and therefore contend, once. Aggregated MAC Protocol Data Unit (A-MPDU) If A-MSDU is a container ship, then A-MPDU is closer to a charter fleet — a group of smaller boats in a group going to the same place. to the MPDU. The pad bits are appended for making the length of A-MPDU subframe a multi-ple of 4 bytes. The pad bits are not appended to the last A-MPDU subframe in IEEE 802.11n while those are appended in IEEE 802.11ac. To form an MPDU, a MAC header is prepended to an MSDU and a Frame Check Sequence (FCS) is appended to the MSDU.
