Using the 802.11h Wireless Mode
There are a number of key points about the IEEE 802.11h standard:
•
802.11h only works for the 802.11a band. It is not required for 802.11b or 802.11g.
•
If you are operating in an 802.11h enabled domain, the AP attempts to use the channel you
assign. If the channel has been blocked by a previous radar detection, or if the AP detects
a radar on the channel, then the AP automatically selects a different channel.
•
When 802.11h is enabled, the initial bootup time increases by a minimum of sixty
seconds. This is the minimum time required to scan the selected channel for radar
interference.
