Using the 2.4-GHz Radio for Backhaul
Until the 7.0 release, mesh used the 5-GHz radio for backhaul, and the 2.4-GHz radio was used only for client
access. The reasons for using only the 5-GHz radio for backhaul are as follows:
• More channels are available
• More EIRP is available
• Less interference occurs
• Most of the client access occurs over the 2.4-GHz band
However, under certain conditions, such as dense foliage areas, you might have needed to use the 2.4-GHz
band for a backhaul because it has better penetration.
With the 7.0.116.0 release, you can configure an entire mesh network to use a single backhaul that can be
either 5 GHz or 2.4 GHz.
Caution
This feature is available only for AP1522 (two radios). This feature should be used only after exploring
the 5-GHz backhaul option.
Caution
We recommend that you use 5 GHz as the first option and use 2.4 GHz only if the 5-GHz option does not
work.
Changing the Backhaul from 5 GHz to 2.4 GHz
When you specify only the RAP name as an argument to the command, the whole mesh sector changes to 2.4
GHz or 5 GHz backhaul. The warning messages indicate the change in backhaul, whether it is from 2.4 GHz
to 5 GHz or vice versa.
The 2.4-GHz backhaul cannot be configured using the controller user interface, but only through the CLI.
Note
To change the backhaul from 5 GHz to 2.4 GHz, follow these steps:
Step 1
To change the backhaul, enter the following command:
