DESCRIPTION
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. 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
device's output power.
Note: Reducing the output power also reduces the device's effective broadcast
radius.
This section controls the data rates permitted for clients.
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.
