Abstract
The method is intended to make it possible to interchange data with any individual one of a large number of objects at a low technical cost. An antenna arrangement (5) which is provided at the fixed station receives signals which are radiated from all the objects located in a predetermined region. Information items on the instantaneous location of the individual objects (1) are derived from these received signals (x(t)). The location information items are used for the purpose of controlling a beam-forming network (6), which is connected to the antenna arrangement (5), such that the antenna arrangement (5) produces a polar diagram for each of the objects, which polar diagram is shaped such that a main receiving lobe is directed at the relevant object, and the reception attenuation is high in comparison with that of the main receiving lobe in the direction of the respectively other adjacent objects. <IMAGE>
