802.11n/ac

Properties of 802.11n/ac
With the IEEE 802.11n/ac standard, it is possible to bundle together individual frames to form
larger frames, A-MPDU and A-MSDU frames.
On this page, you specify the settings for the A-MPDU and A-MSDU frames. Some of the
settings depend on the set transmission standard and the selected channel width.

Configuration Manual, 11/2019, C79000-G8976-C485-03
Multiple MPDU frames with the same destination address are bundled and sent as one
large A-MPDU. This allows the total throughput to be increased.
A-MPDU frames are received but not sent.
Multiple MSDU frames with the same destination address are bundled into one A-MSDU
and sent together. This reduces the network load. Due to their shorter maximum length
A-MSDUs are more suitable for the bundling of several shorter frames.
A-MSDU frames are received but not sent.
