For future readers, I think the frame utilization question was resolved [over here](https://community.cambiumnetworks.com/t/450-lineup-with-firmware-22/90926/10):

> LTE colocation feature now automatically adjusts the allowed range of Downlink Data percentage on the APs **Configuration → Radio** page to ensure no overlap with LTE occurs. In previous releases, PMP 450 APs automatically adjusted the PMP frame start to ensure it aligned with that of LTE. But the selection of a proper downlink data percentage to prevent PMP downlink transmission from overlapping with the LTE uplink transmission from a nearby LTE sector was left up to the operator to use the Cambium tools to calculate and adjust it. In System Release 22.0, this computation is done in software. Also, for any existing PMP sectors already running LTE colocation, when upgrading to System Release 22.0 if the current configuration introduces overlap with LTE, the **Downlink Data** percentage in the **Configuration → Radio** page, is automatically adjusted for the operator to the nearest proper value.
