1. A method comprising:
determining a noise floor for a radio frequency (RF) system;
determining a passive intermodulation (PIM) value of a component of the RF system contributing as a source of PIM;
determining that a passive intermodulation (PIM) cancellation system should be enabled if the PIM value is above a predetermined threshold from the noise floor; and
determining that the PIM cancellation system should be disabled if the PIM value is at or below the predetermined threshold.
