Configuring the Radio Carriers

XPIC Overview
Cross Polarization Interference Canceller (XPIC) is a feature that enables two
radio carriers to use the same frequency with a polarity separation between
them. Since they will never be completely orthogonal, some signal cancelation
is required.
In addition, XPIC includes an automatic recovery mechanism that ensures that
if one carrier fails, or a false signal is received, the mate carrier will not be
affected. This mechanism also ensures that both carriers will be operational,
after the failure is cleared.
To configure and enable XPIC, first configure the antennas and then configure
the carriers, as described below.
