Configuring the Rate Sets
Why do the different radios have different rate sets???
Rate sets specify 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.
ˆ 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 access point will automatically choose the most efficient rate
based on factors like error rates and distance of client stations from
the access point.
ˆ Basic Rate Sets indicate rates that the access point will advertise to
the network for the purposes of setting up communication with other
access points and client stations on the network. It is generally more
efficient to have an access point broadcast a subset of its supported
rate sets.
Figure 46 shows the rate sets for radio one.
