Abstract
A method for implementing a wireless data exchange between a fixed station and sending/receiving devices on board objects moving relative to the fixed station, preferably in lanes, and particularly vehicles. Using an antenna arrangement of the fixed station, the sending and/or receiving profile of which can be electronically aligned with an object, allows reliable determination of location using the antenna arrangement, in that in a first phase, a search territory is swept and checked for response signals from objects by means of a varying alignment of the sending and/or receiving profile. The time of reception of a response signal is correlated with the instantaneous adjustment values of the sending and/or receiving profile to determine the location. In a second phase, the sending and/or receiving profile is fixed on a sending/receiving device of an object whose location has been determined, and it is tracked, if necessary, while the data exchange is conducted.
