In a communications system for communication between a vehicle guided along a predefined movement path and a stationary station using a slotted waveguide which extends parallel to the movement path of the vehicle and into which at least one antenna connected to a transceiver unit of the stationary station and at least one antenna of the vehicle project, wherein the antenna of the vehicle is moved in the longitudinal direction of the slotted waveguide with a movement of the vehicle, a switching device is arranged between the antenna of the vehicle and a transceiver unit of the vehicle, by means of which the antenna can be selectively connected to the transceiver unit of the vehicle either directly or via at least one interconnected attenuation element. The switching device can be actuated by the control device of the vehicle according to the power of a received signal.
A communication system for communication between a vehicle guided along a predetermined movement path and a fixed station using a slotted waveguide that extends parallel to the movement path of the vehicle and into which project at least one antenna connected to a transmitting and receiving device of the fixed station and at least one antenna of the vehicle, wherein the at least one antenna of the vehicle is moved in the longitudinal direction of the slotted waveguide during movement of the vehicle, wherein an attenuation unit with adjustable attenuation is connected between the at least one antenna of the vehicle and a transmitting and receiving device of the vehicle.
