For the DWL-8500AP, use the Radio Settings page to configure both Radio One and Radio
Two. The settings on the page apply only to the radio that you select from the Radio list. After
you configure settings for one of the radios, click Update and then select and configure the
other radio. Be sure to click Update to apply the second set of configuration settings for the
other radio.
Description
Specify an RTS Threshold
The RTS threshold specifies the packet size of the minimum packet
for which a request to send (RTS) frame will be sent. This helps
control traffic flow through the access point, especially one with a
lot of clients.
If you specify a low threshold value, RTS packets will be sent more
frequently. This will consume more bandwidth and reduce the
throughput of the packet.
On the other hand, sending more RTS packets can help the network
recover from interference or collisions which might occur on a
busy network, or on a network experiencing electromagnetic
interference.
Specify the maximum number of stations allowed to associate to
this radio at any one time.
You can enter a value between 0 and 256.
Enter a percentage value for the transmit power level for this
access point.
The default value, which is 100%, can be more cost-efficient than a
lower percentage since it gives the access point a maximum
broadcast range and reduces the number of APs needed.
To increase capacity of the network, place APs closer together and
reduce the value of the transmit power. This helps reduce overlap
and interference among APs. A lower transmit power setting can
also keep your network more secure because weaker wireless
signals are less likely to propagate outside of the physical location
of your network.
Check the transmission rate sets you want the access point to
support and the basic rate sets you want the access point to
advertise:
• Rates are expressed in megabits per second.
• Supported Rate Sets indicate rates that the access point
supports. You can check multiple rates (click an option to
select or de-select a rate). The AP will automatically choose
the most efficient rate based on factors like error rates and
distance of client stations from the AP.
• Basic Rate Sets indicate rates that the access point will
advertise to the network for the purposes of setting up
communication with other APs and client stations on the
network. It is generally more efficient to have an AP broadcast
a subset of its supported rate sets.
