Data Rates
You use the data rate settings to choose the data rates the access point uses for data
transmission. The rates are expressed in megabits per second.
The access point always attempts to transmit at the highest data rate set to Basic.
If there are obstacles or interference, the access point steps down to the highest
rate that allows data transmission. For each of four rates (1, 2, 5.5, and 11
megabits per second), a drop-down menu lists three options:
• Basic (default)—Allows transmission at this rate for all packets, both unicast
and multicast. At least one of the access point’s data rates must be set to
Basic.
• Yes—The access point transmits only unicast packets at this rate; multicast
packets are sent at one of the data rates set to Basic.
• No—The access point does not transmit data at this rate.
You can use the Data Rate settings to set up an access point to serve client devices
operating at specific data rates. For example, to set up the access point for 11
megabits per second (Mbps) service only, select Basic for 11 and select Ye s for
the other data rates. Figure 3-12 shows the Data Rates set up for 11-Mbps service
only.

To set up the access point to serve only client devices operating at 1 and 2 Mbps,
select Basic for 1 and 2 and set the rest of the data rates to Yes. Figure 3-13 shows
the Data Rates set up for 1- and 2-Mbps service only.
