40MHz Protection Channel Offset Select a 20MHz channel offset if the deployment is using channels
that are 20MHz apart (for example, using channels 1, 5, 9, and 13)
or a 25MHz channel offset (default) if the deployment is using
channels that are 25MHz apart (for example, using channels 1, 6,
and 11).
40MHz Channel Busy Threshold Enter the extension channel threshold percentage, which if
exceeded, will disable transmissions on the extension channel
(40MHz).The default threshold is 50%.
Enable Aggregate MSDUs Select to aggregate short packets. Enabling increase the
maximum frame transmission size but increases latency. This
value is disabled by default.
Aggregate MSDU Max Length Enter the maximum length of the aggregate MSDU. The value
range is 2290-4096 bytes.The default is 4096 bytes.
Enable Aggregate MPDUs Select to enable/deselect to disable aggregate MPDUs. Enabling
Aggregate MPDU reduces overhead and increases throughput of
usable data by compiling all of the data into clumps. The size of
each clump is determined by: Aggregate MPDU Max Packets x
Aggregate MPDU Max Length. Enable Aggregate MPDUs is
disabled by default.
Aggregate MPDU Max Length If Enable Aggregate MPDUs is enabled, enter the maximum
bytes of each MPDU packet. The value range is 1024-65535
bytes. The default is 65535 bytes.
Aggregate MPDU Max Packets If Enable Aggregate MPDUs is enabled, enter the maximum
number of packets in each MPDU clump. The value range is 2-64.
the default is 64.
Enable ADDBA Support Select to enable/deselect to disable ADDBA support. ADDBA, or
block acknowledgement, provides acknowledgement of a group of
frames instead of a single frame. ADDBA support is disabled by
default.
