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 per-
cent. 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 transmit power setting
can also keep your network more secure because weaker wireless signals are less likely to propa-
gate 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 automatically
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.
For more information, see description of Mode further up in this table, on page 169.
