The GPS sync source is the same on all APs or is a combination of
“onboard GPS” and CMM4
In this configuration the GPS synchronization source in the whole network
is one of the following:
1- “onboard GPS” or
2- CMM4 or
3- CMM3 or
4- Mix of “onboard GPS” and CMM4 (but NOT CMM3)
For instructions on how to configure Frequency Reuse Mode to ensure that
interference is reduced throughout the deployment, see Figure 36 .

The rules in selecting the APs to enabling the Frequency Reuse Mode in
this deployment are:
1- Only ONE of the APs on the same tower configured with the same
frequency must be configured with the Frequency Reuse Mode
parameter set to Frequency-Reuse-Back; the other AP must be
configured with Frequency Reuse Mode set to Frequency-Reuse-
Front.
Also, APs on different towers facing each other with overlapped
coverage must be configured with Frequency Reuse Mode set to
Frequency-Reuse-Back.
