Abstract
In order to improve a cable, comprising an inner cable body, in which electrical conductor strands run in the longitudinal direction of the cable, a cable sheath, enclosing the inner cable body and lying between an outer surface of the cable and the inner cable body, and at least one information carrier unit, disposed within the outer surface of the cable, to increase the range of communication between the information carrier unit and the read/write device, it is proposed to provide the information carrier unit having an antenna unit, which can be coupled with a read/write device by parasitic electromagnetic fields between the antenna unit and at least two of the electrical conductor strands of the inner cable body.
