Should I Enable Mpdu Aggregation?

You should generally turn Optimized AMPDU aggregation function disabled when you are running time critical applications such as online gaming or VoIP. The reason is that the AMPDU is less efficient and slower by itself. You want faster and immediate transmission of data rather than aggregation through the router.

Which is better MSDU or Mpdu?

Compared to the A-MSDU, the A-MPDU has more overhead since every frame has its own MAC header. However, it is also much more resilient because in case of frame loss, only the frames not being Ack'd in the Block Ack have to be retransmitted.

What is Mpdu aggregation state?

An MPDU consists of a frame header, body and trailer with the MSDU payload encapsulated in the frame body. 802.11n defined two methods of frame aggregation. The first method of frame aggregation known as Aggregate MAC Service Data Unit (A-MSDU) aggregates multiple MSDUs into a single frame transmission.
