ABSTRACT:
A system, for bidirectional transmission of electromagnetic data signals between a stationary unit and a vehicle unit, in which at least two antennas can be used, is proposed. The antennas are aligned at a predetermined distance and at a predetermined height from one another, in such a way that reflection from the roadway and from vehicles is minimized. In the uplink mode, the antenna having the best reception properties is selected, so that reliable data transmission to the stationary unit takes place.
