Abstract (en)
[origin: EP0578060A2] The method should make it possible to exchange data with each individual or one of a multiplicity of objects with little technical expenditure. An antenna arrangement (5) present on the base station repeatedly receives signals radiated by all objects located within a predetermined region. From these received signals (x(t)) information on the instantaneous location of the individual objects (1) is derived. The location information is used for controlling a beam forming network (6) connected to the antenna arrangement (5), in such a manner that the antenna arrangement (5) generates for each of the objects a directional pattern which is formed in such a manner that a main receiving lobe is directed towards the relevant object and the reception attenuation is high in the direction of in each case the other adjacent objects in comparison with the main receiving lobe. <IMAGE>
