The Intermodulation Interference (IM) occurs when the two transmitters are in close proximity and their signals mix in one or both of their final amplifiers. This generates unwanted signals at the sum and difference of the original frequency transmissions.

Passive Intermodulation (PIM) is an intermodulation distortion that occurs in linear devices (e.g. cables, connectors and antennas) as unwanted signals created by the mixing of two or more strong RF signals due to a loose or corroded connector, or nearby rust.
