The following table describes the labels in this screen.
Table 14 The Profile Edit > Radio > Edit Screen
LABEL DESCRIPTION
Profile Name Enter a name identifying this profile.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant
WLAN devices to associate with the NWA.
Select 802.11g Only to allow only IEEE 802.11g compliant
WLAN devices to associate with the NWA.
Select 802.11b+g to allow both IEEE802.11b and IEEE802.11g
compliant WLAN devices to associate with the NWA. The
transmission rate of your NWA might be reduced.
Select 802.11a (NWA-3160 only) to allow only IEEE 802.11a
compliant WLAN devices to associate with the NWA.
Super Mode Select this to improve data throughput on the WLAN by enabling
fast frame and packet bursting.
Choose Channel ID 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.
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 (256) turns on the RTS/CTS handshake. Enter a
value between 256 and 2346.
Fragmentation
Threshold
The threshold (number of bytes) for the fragmentation boundary
for directed messages. It is the maximum data fragment size that
can be sent. Enter an even number between 256 and 2346.
Beacon Interva
When a wirelessly networked device sends a beacon, it includes
with it a beacon interval. This specifies the time period before the
device sends the beacon again. The interval tells receiving
devices on the network how long they can wait in low-power
mode before waking up to handle the beacon. This value can be
set from 30ms to 1000ms. A high value helps save current
consumption of the access point.
DTIM
Delivery Traffic Indication Message (DTIM) is the time period after
which broadcast and multicast packets are transmitted to mobile
clients in the Active Power Management mode. A high DTIM value
can cause clients to lose connectivity with the network. This value
can be set from 1 to 100.
Output Power Set the output power of the NWA in this field. If there is a high
density of APs in an area, decrease the output power of the NWA
to reduce interference with other APs. Select one of the following
100%(Full Power), 50%, 25%, 12.5% or Minimum. See the
product specifications for more information on your NWA’s output
power.
