Receive Quality
Debug To aid in link performance monitoring, the AP and SM now report the
number of fragments received per modulation (i.e. QPSK, 16-QAM, 64-QAM)
and per channel (polarization).
Note
Due to CPU load, this will slightly degrade packet per second
processing.

OFF
By default, frame start is
aligned with devices with

If the synchronization
source changes (due to
Autosync or otherwise)
the radio will dynamically
adjust its frame start to
maintain alignment with
