<p>A method for densifying a transmitter and a receiver network for mobile telephony, the network being comprised of base stations which each have three cells whose directions are mutually spaced by 120 degrees, where at least four different base stations have mutually different frequency-sets in the cells, and where base stations of different frequency-sets are being placed in a repetitive pattern, i.e. a so-called 4/12-frequency pattern. A first densification is achieved by causing a centre base station (10) that has a first frequency-set (G) and is located in a generally rhomboidal pattern to change its frequency-set to the same frequency-set (R) as the base stations (11-14) located in the corners of the rhomboidal pattern (7); by arranging further base stations (15-22) inwardly of the confines of the rhomboidal pattern (7); and selecting the frequency-sets of respective further base-stations (15-22) so that the frequency or frequencies of their cells will deviate from the frequency of frequencies of the cells of the nearest base stations.</p> |
