Sets the communication speed of multicast packets.
Enable to use 802.11n protection. 802.11n protection gives priority to 802.11n devices in
mixed mode (11b/g or 11 A) networks.
Set the beacon responding interval (1 -255) for which the AirStation responds to a
wireless device. This setting is effective only when power management is enabled for
the wireless device.
If enabled, Wireless Client Isolation blocks communication between wireless devices
connected to the AirStation. Wireless devices will be able to connect to the Internet
but not with each other. Devices that are connected to the AirStation with wired
connections will still be able to connect to wireless devices normally.
This sets the power of the wireless signal. Because the wireless transmission output and
signal distance range are nearly proportional, when the wireless transmission output is
reduced, the signal distance range also becomes shorter.
Check Display to set priorities.
You don't usually need to change these settings. Using the default settings is
recommended.
Priority
The following priorities may be applied to individual transmission packets: (Highest) 8,
(High) 4, (Normal) 2, and (Low) 1. From the queue, these packets are processed in order
of priority.
CWmin, CWmax
The maximum and minimum value of the contention window. The contention window is
used in the frame collision avoidance structure performed in IEEE802.11, and generally,
the smaller the value in the window, the higher the probability that the queue obtains
the right to send.
AIFSN
The interval to send frames. The unit of the AIFSN is a slot, just as the window defined
by CWmin and CWmax is. The smaller the interval of sending frames, the faster the
algorithm can restart. As a result, the priority of the queue is higher.
TXOP Limit
The period of time that the queue can use after obtaining the right to send. The unit is
32 ms. The longer this time, the more frames can be sent per right to send. However, the
queue may interfere with other packet transmissions. If TXOP Limit is set to 0 (zero), only
one frame can be sent per right to send.
Admission Control
Restricts new frames from interfering with a previous queue. New packets are prioritized
lower until a queue of them is collected. As the new queue accumulates more packets,
its priority increases.
