Configuring Radio Settings
RTS Threshold Specify an RTS Threshold value between 0 and 2347 .
The RTS threshold specifies the packet size of a request to send (
RTS ) transmission. This helps con-
trol 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 colli-
sions which might occur on a busy network, or on a network experiencing electromagnetic interference.
Maximum
Stations
Specify the maximum number of stations allowed to access this AP at any one time.
You can enter a value between
0 and 2007 .
Transmit Power Provide a percentage value to set the transmit power for this access point.
The default is to have the access point transmit using
100 percent of its power.
Recommendations:
• For most cases, we recommend keeping the default and having the transmit power set to
100 percent. This is more cost-efficient as 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 will help reduce overlap and interference among APs. A lower trans-
mit 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.
Rate Sets 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 a checkbox 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.
