Parameter Description Range Default
The 802.11n standard specifies two guard
intervals: 400ns (short) and 800ns (long).
Enabling a short guard interval can
decrease network overhead by reducing
unnecessary idle time on each AP. Some
outdoor deployments, may, however require
a longer guard interval. If the short guard
interval does not allow enough time for
reflections to settle in your mesh
deployment, inter-symbol interference
values may increase and degrade
throughput.
This parameter is enabled by default.
short-guard-intvl-80Mhz
Enable or disable use of short (400ns) guard
interval in 80 MHz mode.
A guard interval is a period of time between
transmissions that allows reflections from
the previous data transmission to settle
before an AP transmits data again. An AP
identifies any signal content received inside
this interval as unwanted inter-symbol
interference, and rejects that data.

stbc-rx-streams
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-AP130
Series, W-AP175 and W-AP105 only. The
configured value will be adjusted based on
AP capabilities.)

stbc-tx-streams
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-AP175, W-
AP130 Series and W-AP105 only. The
configured value will be adjusted based on
AP capabilities.)
