Tuning The Transmit Data Rate - Nortel 2300 Series Configuration Manual

294 Configuring RF Auto-Tuning
A radio also can change its channel before the channel tuning interval expires to respond to RF anomalies. An RF
anomaly is a sudden major change in the RF environment, such as sudden major interference on the channel.
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
As described in "Power Tuning" on page
