Parameter Description
Legacy stations Control whether or not legacy (non-HT) stations are allowed
to associate with this SSID. By default, legacy stations are
allowed to associate. This setting has no effect on a BSS in
which HT support is not available.
Default: Enabled.
Low-density Parity Check If enabled, the AP will advertise Low-density Parity Check
(LDPC) support. LDPC improves data transmission over radio
channels with high levels of background noise.
Default: Enabled.
Maximum number of spatial streams usable for
STBC reception
Control the maximum number of spatial streams usable for
Space-Time Block Code (STBC) reception. 0 disables STBC
reception, 1 uses STBC for MCS 0-7. Higher MCS values are
not supported. (Supported on the OAW-AP105, OAW-AP130
Series, and OAW-AP170 Series only. The configured value
will be adjusted based on AP capabilities.)
Default: 1.
NOTE: If transmit beamforming is enabled, STBC will be
disabled for beamformed frames.
Maximum number of spatial streams usable for
STBC transmission.
Control 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 OAW-AP105, OAW-AP130 Series, and OAW-
AP170 Series only. The configured value will be adjusted
based on AP capabilities.)
Default: 1.
NOTE: If transmit beamforming is enabled, STBC will be
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.
Default: Enabled.
Max received A-MPDU size Control the maximum size, in bytes, of an Aggregated-MAC
Packet Data Unit (A-MPDU) that can be received on this high-
throughput SSID.
Default: 65535 bytes.
Max transmitted A-MPDU size Control the maximum size, in bytes, of an A-MPDU that can
be sent on this high-throughput SSID.
Range: 1576–65535 bytes.
Min MPDU start spacing Minimum time between the start of adjacent MPDUs within
an aggregate MPDU, in microseconds.
Range: 0 (No restriction on MDPU start spacing), .25 µsec, .5
µsec, 1 µsec, 2 µsec, 4 µsec.
Default: 0.
