Hello Maryanne,

I would recommend you to look at the KB articles regarding GPS Sync and Frequency Re-use.

[http://community.cambiumnetworks.com/t5/ePMP-Synchronization/ePMP-GPS-Synchronization/m-p/37884#M1](https://community.cambiumnetworks.com/t/epmp-gps-synchronization/39470)

[http://community.cambiumnetworks.com/t5/ePMP-Synchronization/Mitigating-self-interference-in-an-ePMP-ABAB-frequency-reuse/m-p/38203#M2](https://community.cambiumnetworks.com/t/mitigating-self-interference-in-an-epmp-abab-frequency-reuse-deployment/39583)

Since you are planning to have overlapping sectors, we recommend a minimum frequency gap of 2 or 3 channel widths &nbsp;edge-to-edge for&nbsp;the operating frequencies of the overlapping sectors, in addition to the 5MHz frequency gap edge-to-edge for adjacent sectors.

Regards
