The method involves dividing the communication space into a number of three-dimensional cells. A group of predetermined transmission frequencies is allocated to each cell, such that two adjacent cells have distinct groups of frequencies. Messages are transmitted using at least one of the allowed frequencies using either mobile or fixed radio telephones. The division of the communication space can be made according to tiled patterns, cubes, hexagonal cylinders, double crosses and other multi-facetted shapes. <IMAGE> |
