Abstract
An arrangement of an area covering, cellular radio communication network having cell regions which can be. contiguously replicated without interference. A central transceiver station is coupled to a base station controller and has a plurality of decentral transceiver stations surrounding and coupled to the central transceiver station. Groups of adjacent decentral transceiver stations are grouped in respective cell areas. All of the decentral transceiver stations in each cell area are allocated the same transmission frequencies, but the frequencies of each cell area are different from the other cell areas in the cell region.
