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 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.

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.

To support both “b” and “g” clients, change the radio Mode to I

EEE 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 I

EEE 802.11g

. The Web UI will automatically select the

default Rate Sets. Now add

, and

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.
