Parameter Description
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
Displays 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 W-AP105, W-AP130 Series,
and W-AP175 only. The configured value will be adjusted
based on AP capabilities.)
NOTE: If transmit beamforming is enabled, STBC will be
disabled for beamformed frames.
Maximum number of spatial streams
usable for STBC transmission
Displays 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-AP105, W-AP130 Series, and W-AP175
only. The configured value will be adjusted based on AP
capabilities.)
NOTE: If transmit beamforming is enabled, STBC will be
disabled for beamformed frames.
MPDU Aggregation
Displays if the profile enables or disables MAC Protocol Data
Unit (MPDU) aggregation.
Default: Enabled.
Max received A-MPDU size
Displays the configured maximum size of a received
aggregate MPDU, in bytes.
Max transmitted A-MPDU size
Displays the configured maximum size of a transmitted
aggregate MPDU, in bytes.
Min MPDU start spacing
Displays the configured minimum time between the start of
adjacent MPDUs within an aggregate MPDU, in
microseconds.
Short guard interval in 20 MHz mode
Displays if the profile enables or disables use of short (400
ns) guard interval in 20 MHz mode.
Default: Enabled.
Short guard interval in 40 MHz mode
Displays if the profile enables or disables use of short (400
ns) guard interval in 40 MHz mode.
Default: Enabled.
Short guard interval in 80 MHz mode
Displays if the profile enables or disables use of short (400
ns) guard interval in 80 MHz mode.
