question on patrolling feature

[Mafooo]

Does the deception unit that is causing disruption of T mode units have to be in deception range of the patrolling unit for that deception unit disruption effect to be nullified?

The reason I ask is that I am playing a game where a hidden deception unit is disrupting my T mode units, yet the disruption is continuing to take place ADJACENT to a inf unit that I have placed in patrol mode. The deception range for my side is 4, so im thinking my unit on patrol would nullify enemy deception units disruption ability within 4 hexes of my unit on patrol, no? Or...does my patrol unit only nullify the disruption effect if the enemy deception unit is within 4 hexes of my patrol unit? Someone clarify this for me..
