Preamble Type
Select
Dynamic
to have the NWA automatically use short preamble when the wireless
network your NWA is connected to supports it, otherwise the NWA uses long preamble.
Select
Long
preamble if you are unsure what preamble mode the wireless device your
NWA is connected to supports, and to provide more reliable communications in busy
wireless networks.
RTS/CTS
Threshold
(Request To Send) The threshold (number of bytes) for enabling RTS/CTS handshake.
Data with its frame size larger than this value will perform the RTS/CTS handshake.
Setting this attribute to be larger than the maximum MSDU (MAC service data unit) size
turns off the RTS/CTS handshake. Setting this attribute to its smallest value (1) turns on
the RTS/CTS handshake.
Extension
channel
protection mode
You can use
CTS to self
or
RTS-CTS
protection mechanism to reduce conflicts with other
wireless networks or hidden wireless clients. The throughput of
RTS-CTS
is much lower
than
CTS to self
. Using this mode may decrease your wireless performance.
A-MPDU
aggregation
This field is available only when
802.11 b/g/n
is selected as the
Wireless Mode
. Select
Enable
to allow the grouping of several A-MSDUs (Aggregate MAC Service Data Units)
into one large A-MPDU (Aggregate MAC Protocol Data Unit). This function allows faster
data transfer rates.
Short GI
This field is available only when
802.11 b/g/n
is selected as the
Wireless Mode
. Select
Enable
to use
Short GI
(Guard Interval). The guard interval is the gap introduced
between data transmission from users in order to reduce interference. Reducing the GI
increases data transfer rates but also increases interference. Increasing the GI reduces
data transfer rates but also reduces interference.
