1. A device for wireless transmission and evaluation of signals and switching statuses from at least one mobile device (10) to a second device (11), where at least one of the devices is capable of moving over a predefined travel path, with a transmission link (12) between devices (10) and (11), with a transmission for feeding the energy supply for mobile device (10), with at least one sensor device (9), connected to mobile device (10), which brings about modulation on transmission link (12) between the two devices in accordance with a random signal string of the sensor, with a receiving device for modulation in device (11), wherein a transmission device for transmission across transmission line (12) comprises at least two coupled coil devices (13, 14), which are mechanically and topologically independent of each other, and wherein at least one coil device (13, 14) is constructed by plugging together individual, modular coil elements (2), in order to realize links of any length.
