Although the backhaul uplink is always provided by the highest numbered radio on the AP, the
channel usage on that radio can vary between two (or more) backhaul nodes, as shown in
Figure
9.
There are no restrictions on the frequency band, channel, or channel-width for the radio being
used for backhaul. For nodes that require wireless backhaul, channel parameters are inherited
from the parent AP and are not configured independently on the child AP.
A radio that is participating in the mesh service will not change channels and only performs
rogue detection/mitigation on the home channel.
When using a Per-Hop Distinctive Backhaul channel (shown in
Figure
9), the second radio of
the parent AP is used to exchange mesh information with the downlink radio (which itself might
be the first or second radio of the child AP).
