Configuring Radio Data Rates
You use the data rate settings to choose the data rates the wireless device uses for data transmission. The
rates are expressed in megabits per second. The wireless device always attempts to transmit at the highest
data rate set to Basic, also called Require on the browser-based interface. If there are obstacles or
interference, the wireless device steps down to the highest rate that allows data transmission. You can
set each data rate to one of three states:
At least one data rate must be set to basic.
Note
You can use the Data Rate settings to set an access point to serve client devices operating at specific data
rates. For example, to set the 2.4-GHz radio for 11 megabits per second (Mbps) service only, set the
11-Mbps rate to Basic and set the other data rates to Disabled. To set the wireless device to serve only
client devices operating at 1 and 2 Mbps, set 1 and 2 to Basic and set the rest of the data rates to
Disabled. To set the 2.4-GHz, 802.11g radio to serve only 802.11g client devices, set any Orthogonal
Frequency Division Multiplexing (OFDM) data rate (6, 9, 12, 18, 24, 36, 48, 54) to Basic. To set the
5-GHz radio for 54 Mbps service only, set the 54-Mbps rate to Basic and set the other data rates to
Disabled.
You can configure the wireless device to set the data rates automatically to optimize either the range or
the throughput. When you enter range for the data rate setting, the wireless device sets the 1 Mbps rate
to basic and the other rates to enabled. When you enter throughput for the data rate setting, the wireless
device sets all four data rates to basic.
Beginning in privileged EXEC mode, follow these steps to configure the radio data rates:

Basic (the GUI labels Basic rates as Required)—Allows transmission at this rate for all packets, both
unicast and multicast. At least one of the wireless device's data rates must be set to Basic.
Enabled—The wireless device transmits only unicast packets at this rate; multicast packets are sent
at one of the data rates set to Basic.
Disabled—The wireless device does not transmit data at this rate.
Purpose
Enter global configuration mode.
Enter interface configuration mode for the radio interface. The
2.4-GHz radio is radio 0, and the 5-GHz radio is radio 1.
