DESCRIPTION
Select this to enable A-MSDU aggregation.
Mac Service Data Unit (MSDU) aggregation collects Ethernet frames
without any of their 802.11n headers and wraps the header-less
payload in a single 802.11n MAC header. This method is useful for
increasing bandwidth throughput. It is also more efficient than A-
MPDU except in environments that are prone to high error rates.
Enter the maximum frame size to be aggregated.
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.
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.
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 80ms to 1000ms. A
high value helps save current consumption of the access point.
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 255.
Set the output power of the AP in this field. If there is a high density
of APs in an area, decrease the output power of the NWA5160N to
reduce interference with other APs. Select one of the following
100%(Full Power), 50%, 25%, or 12.5%. See the product
specifications for more information on your NXC's output power.
Note: Reducing the output power also reduces the NXC's
effective broadcast radius.
For each Rate, select a rate option from its list. The rates are:
• Fast Select - Select an 802.11 broadcast frequency to determine
the baseline rate configuration.
• Basic Rate (Mbps) - Set the basic rate configuration in Mbps.
• Support Rate (Mbps) - Set the support rate configuration in
Mbps.
• MCS Rate - Set the MCS rate configuration.
This section allows you to associate an SSID profile with the radio
profile.
