Maximum VHT MPDUsize
Maximum size of a VHT MPDU, in bytes.
Range: 3895, 7991, 11454
Min MPDU start spacing Minimum time between the start of adjacent MPDUs within an aggregate
MPDU, in microseconds. Allowed values: 0 (No restriction on MDPU start
spacing), .25 µsec, .5 µsec, 1 µsec, 2 µsec, 4 µsec.
Short guard interval in 20
MHz mode
Enable or disable use of short (400ns) guard interval in 20 MHz mode. This
parameter is enabled by default.
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. 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.
