Description
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.
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.
To support both "b" and "g" clients, change the radio Mode to IEEE 802.11g. The Web UI will automat-
ically select the default Rate Sets that allow both "b" and "g" clients to connect.
To support only "g" clients, change the radio Mode to IEEE 802.11g. The Web UI will automatically
select the default Rate Sets. Now add 24, 12, and 6 as Basic Rates. This will prevent "b" clients from
connecting since they do not support these rates, but will allow "g" clients to connect since they are
required by the standard to support these rates.
