394 Configuring Auto-RF
NN47250-500 (Version 03.01)
By default, a radio cannot change its channel more often than every 900 seconds, regardless of the RF environment. This
channel holddown avoids unnecessary changes due to very transient RF changes, such as activation of a microwave
oven.

Tuning the transmit data rate

A radio sends beacons, probe requests, and probe responses at the minimum transmit data rate allowed for clients. This
gives them the maximum distance. All other packets are transmitted at a rate determined by their destination. All packets
are transmitted at the same power level.
By default, the following minimum data rates are allowed:
5.5 Mbps for 802.11b/g clients
24 Mbps for 802.11a clients
You can statically change the transmit data rates for radios, on a radio profile basis. (For information, see “Changing
transmit rates” on page 308.) However, Auto-RF does not change transmit rates automatically.
