Vertical:
The polarization of the antenna is vertical, in the same direction as the
AirMax5. This settings is the default and most used.
Horizontal:
The polarization of the antenna is horizontal, 90 degree from the
direction of the case.
Diversity:
The AirMax5 will auto switch between vertical and horizontal
antennas based on the RSSI level detected. However, the performance can
suffer if the switching happens too frequently.
Please read more about Antenna information on
Chapter 7: Antenna Alignment
.
Noise Immunity:
Adaptive Noise Immunity is one of the new function in Atheros
driver to enhance the performance in interference environment.
AckTimeOut:
When a packet is sent out from one wireless station to the other, it will
waits 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.
The easiest way to enter AckTimeOut value is by entering the distance in “
Operation
Mode -> Setup -> Distance
”. The AirMax5 will then calculate and enter the correct
value for you.
Enable Radio eXtended Range
: XR is Atheros eXtended technology to increase
range. When XR is turned on, the radio can increase the receiver sensitivity greatly.
However, performance may be reduced significantly also. Use this mode only if you
can trade more distance for lower performance.
Enable privacy separator:
Select the check box to prohibit data transmission
between client stations. This function is also known as “Client Isolation”.
Enable 802.1d:
Enable the Spanning Tree Protocol to prevent forming a network loop.
This option is especially important for WDS Bridge mode.
Enable 802.11d:
Also known as “Global Roaming”. 802.11d is a standard for use in
countries where systems using other standards in the 802.11 family are not allowed to
operate.
