[Batman: Arkham City] Why did the thugs use frequency jammers?

How did they know that their jammers could be used to disrupt Batman's cowl technology? They would have had access to Batman's tech or at least know Batman has that technology but isn't it some big secret? If they were just jamming all cell signals the. wouldn't the times he's underground have jammed his signals as well?

I don't remember the timeline exactly, but if they got that tech around the same time they got all their guns, then it was Strange supplying them. Maybe Batman's cowl tech isn't a secret; maybe the thugs are just taking the jammers on faith.
