FREQ.
BANDS
Bandwidth at which the Dash wireless card communicates with wireless
network.
Dash provides below frequency bands to communicate:
• All Bands (2.4GHz and 5.1GHz)
• 2.4GHz Band Only
• 5.1GHz Band Only
• 5.1GHz Band priority over 2.4GHz Band
• 2.4GHz Band priority over 5.1GHz Band
Default value of the frequency band is “All Bands” (2.4GHz and
5.1GHz).
RTS
THRESHOLD
Request to Send (RTS) and Clear to Send (CTS) is the communication
exchange used to reduce collisions introduced by the hidden node
problem. RTS/CTS exchanges will occur for unicast data frames that
are of a larger size than the RTS threshold value. Using a small
threshold value causes RTS frames to be sent more often, consuming
more of the available bandwidth, therefore reducing the apparent
throughput of the network packet. However, the more RTS packets that
are sent, the quicker the system can recover from interference or
collisions -- as would be the case in a heavily loaded network, or a
wireless network with much electromagnetic interference. If however, it
is found that enabling RTS/CTS results in decreased throughput, it is
recommended to disable the feature, even if the number of collisions
are reduced. A valid range for RTS Threshold is 0 - 2347 bytes.
Use the default RTS Threshold value
2347
, unless otherwise specified
in the wireless network design.”
FRAG.
THRESHOLD
Fragmentation Threshold specifies the maximum frame size a wireless
device can transmit without fragmenting the frame. A valid
Fragmentation Threshold is a numeric value within the range of 256 to
2346.
Use the default Fragmentation Threshold value 2346, unless otherwise
specified in the wireless network design.
QOS CONFIG
Quality of service (QoS) is the ability to prioritize traffic from the Dash
above other, less critical, data on the wireless network.
Dash supports configuring the QoS settings according to WMM
standard guidelines. Options
WMM
and
NONE
are available to
configure the QoS Settings.
Default QoS configuration is
WMM
.
Dash also supports the upstream Quality of Service with the default
values for QoS parameters (CWmin, CWmax, AIFS, TXOP and DSCP
markings), which are available in
BOOT MENU
for configuration.
