摘要：A method for densifying a transmitter and a receiver network for mobiletelephony. The network includes base stations that each have three cells that aremutually spaced at 120° intervals about the base station. At least four different basestations have mutually different frequency sets in the cells, and base stations of differentfrequency sets are placed in a repetitive pattern, a so-called 4/12- frequency pattern. Afirst densification is achieved by causing a center base station that has a first frequencyset, and that is located within a generally rhomboidal pattern of base stations, to changeits frequency set to the same frequency set as the base stations located at the corners ofthe rhomboidal pattern. Additional base stations are positioned within the rhomboidalpattern, and the frequency sets of the additional base stations are selected so that thefrequency or frequencies of their cells will differ from the frequency or frequencies ofthe cells of the nearest base station.
