Parameter Description
Temporal Diversity
Enable
When a client is not responding to 802.11 packets, the AP will launch two
hardware retries. If you enable this option and hardware retries are not
successful, then the AP will launch and the software retries.
BA AMSDU Enable Enable/Disable Receive AMSDU in BA negotiation.
Legacy stations Allow or disallow associations from legacy (non-HT) stations. By default, this
parameter is enabled (legacy stations are allowed).
Low-density Parity Check If enabled, the AP advertises Low-density Parity Check (LDPC) support LDPC
improves data transmission over radio channels with high levels of
background noise. (For W-AP130 Series only)
Maximum number of
spatial streams usable for
STBC reception
Controls the maximum number of spatial streams usable for STBC
reception. 0 disables STBC reception, 1 uses STBC for MCS 0-7. Higher MCS
values are not supported. (Supported on the W-AP90 Series, W-AP130
Series, W-AP68, W-AP175 and W-AP105 only. The configured value adjusts
based on AP capabilities.)
If transmit beamforming is enabled, STBC is disabled for disabled for
beamformed frames.
Maximum number of
spatial streams usable for
STBC transmission.
Controls the maximum number of spatial streams usable for STBC
transmission. 0 disables STBC transmission, 1 uses STBC for MCS 0-7.
Higher MCS values are not supported. (Supported on W-AP90 Series, W-
AP175, W-AP130 Series and W-AP105 only. The configured value adjusts
based on AP capabilities.)
If you enable transmit beamforming, STBC is disabled for disabled for
beamformed frames.
MPDU Aggregation Enable or disable MAC protocol data unit (MPDU) aggregation.
High-throughput APs are able to send aggregated MAC protocol data units
(MDPUs), which allow an AP to receive a single block acknowledgment
instead of multiple ACK signals. This option, which is enabled by default,
reduces network traffic overhead by effectively eliminating the need to
initiate a new transfer for every MPDU.
Max received A-MPDU
size
Maximum size of a received aggregate MPDU, in bytes. Allowed values:
8191, 16383, 32767, 65535.
Max transmitted A-MPDU
size
Maximum size of a transmitted aggregate MPDU, in bytes.
Range: 1576–65535
Maximum number of
MSDUs in an A-MSDU on
best-effort AC
Maximum number of MSDUs in a TX A-MSDU on best-effort AC. TX-AMSDU
disabled if 0.
Range: 0-15
Default: 2
Maximum number of
MSDUs in an A-MSDU on
Maximum number of MSDUs in a TX A-MSDU on background. TX-AMSDU
disabled if 0.
