DTIM Interval:
The A.DUO buffers packets for stations that operate in the
power-saving mode. The Delivery Traffic Indication Message (DTIM) informs such
power-conserving stations that there are packets waiting to be received by them. The
DTIM interval specifies how often the beacon frame should contain DTIMs. It should
have a value between 1 to 255, with a default value of 3.
User Limitation:
This limitation applies to number of wireless clients the device can
associate. If you need to serve wireless connection to large number of users in one
location. You can deploy many APs and limit the number of wireless clients, so any
additional wireless connection attempt will be rejected (therefore, redirect to other AP).
The range of user limitation is from 1 to 100.
Age Out Timer:
Set the age out timer for the wireless client. If there is no traffic from
client for more than the timer, the wireless client will be dropped. The default is 300 sec.
This function is available only for the Access Point and AP router mode.
Transmit Power:
You can adjust the transmit output power of the A.DUO’s radio from
10dBm to 24dBm. The higher the output power, the more distance A.DUO can deliver.
However, it is advised that you use just enough output power so it will not create
excessive interference for the environment. Also, using too much power at close
distance can create serious performance drop due to signal distortion. At less than
200meter distance, the best output power is about 14dBm. At 2km distance; the best
output power setting is 18dBm for “11a” and “Super-A without Turbo”, 24dBm for
“Super-A with Static/Dynamic Turbo”.
Rate Control:
Select here to change the Data Rate for the radio. Lower data rate
sometimes provide longer distance. In most cases, however, we recommend to keep
the setting at “Best”.
AckTimeOut:
When a packet is sent out from one wireless station to the other, it will
wait for an Acknowledgement frame from the remote station. The station will only wait
for a certain amount of time; this time is called the ACK timeout. If the ACK is NOT
received within that timeout period then the packet will be re-transmitted resulting in
reduced throughput. If the ACK setting is too high, then throughput will be lost due to
waiting for the ACK Window to timeout on lost packets. If the ACK setting is too low
then the ACK window will have expired and the returning packet will be dropped,
greatly lowering throughput. By having the ability to adjust the ACK setting we can
effectively optimize the throughput over long distance links.
