Abstract

A ring-shaped network structure having a plurality of rings of range sections and a sector subdivision is provided, the number of which corresponds to the number of cells positioned along a ring. Positioned in the center is a base station with antennae arranged at a raised location for illuminating all cells or for the reception from the individual cells respectively. The antennae are designed as strongly focusing directional antennae which supply at least two cells lying in radial direction from the antenna location within the same sector with the same frequency in each case.
