RTS/CTS Threshold Use RTS/CTS to reduce data collisions on the wireless network if
you have wireless clients that are associated with the same AP
but out of range of one another. When enabled, a wireless client
sends an RTS (Request To Send) and then waits for a CTS (Clear
To Send) before it transmits. This stops wireless clients from
transmitting packets at the same time (and causing data
collisions).
A wireless client sends an RTS for all packets larger than the
number (of bytes) that you enter here. Set the RTS/CTS equal to
or higher than the fragmentation threshold to turn RTS/CTS off.
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 Interval 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.
Note: Reducing the output power also reduces the NWA’s
effective broadcast radius.
Rates Configuration This section controls the data rates permitted for clients.
For each Rate , select an option from the Configuration list. The
options are:
• Basic (1~11 Mbps only): Clients can always connect to the
access point at this speed.
• Optional : Clients can connect to the access point at this
speed, when permitted to do so by the AP.
• Disabled : Clients cannot connect to the access point at this
speed.
Select SSID Profile Use this section to choose the SSID profile or profiles you want
access points using this radio profile to use. Each AP can use
multiple SSID profiles simultaneously.
Configure SSID profiles in the Profile Edit > SSID screens.
Enable Antenna
Diversity Select this to use antenna diversity. Antenna diversity uses
multiple antennas to reduce signal interference.
