Wireless Traps are Traps that can operate wirelessly, not connected to the foot pedal.
History[]
In 2004, on the run from the Ghost Legion in Ecto-1, Winston Zeddemore got an idea. He used duct tape to bind several Wireless Traps together into a ball then tossed them out the rear hatch and activated them simultaneously. The ad hoc strategy worked and several of the ghosts were trapped.
