DESCRIPTION
This field displays only when you select 802.11a or 802.11n/a
in the 802.11 Radio Mode field. Select this if you do not want to
use DFS (Dynamic Frequency Selection).
DFS (dynamic frequency selection) allows an AP to detect other
devices in the same channel. If there is another device using the
same channel, the AP changes to a different channel, so that it
can avoid interference with radar systems or other wireless
networks.
(For NWA-3160 and NWA-3163)
Select this to improve data throughput on the WLAN by enabling
fast frame and packet bursting.
Set the operating frequency/channel depending on your
particular region.
To manually set the NWA to use a channel, select a channel from
the drop-down list box. Click MAINTENANCE and then the
Channel Usage tab to open the Channel Usage screen to make
sure the channel is not already used by another AP or
independent peer-to-peer wireless network.
To have the NWA automatically select a channel, click Auto
Selection instead.
Click this to disable DCS and select a channel ID manually.
DCS is Disabled by default
If the NWA is configured in Controller AP mode, it is
recommended that you enable Dynamic Channel Selection
(DCS). This allows the NWA to select channels with less
intereference for Managed APs.
This field is available only when 802.11n/g or 802.11n/a is
selected as the 802.11 Radio 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.
This field is available only when 802.11n/g or 802.11n/a is
selected as the 802.11 Radio 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.
