Abstract
A system is described for the spatial allocation of at least one transponder to cells of a detection area. The cells of the detection area differ by changeable or permanently different properties of an electromagnetic field. By means of the transponder, the properties of the electromagnetic fields of the cells which are capable of reception individually, selectively, or resultantly, are evaluated. Allocation to the cells is effected automatically according to the properties of the individual electromagnetic fields received, or according to the ratio of the proportions of the electromagnetic fields received selectively or resultantly, or according to the proportion predominating in the field strength of the electromagnetic fields received selectively or resultantly.
