  • Patent number: 6061567
    Abstract: A telecommunications system and method for cell planning is disclosed which reduces the co-channel interference between cell clusters by alternating the antenna-pointing azimuth angle between "rows" of cell clusters within a cellular system. Thus, for a mobile terminal within a serving cell of a serving cluster, the antenna pointing azimuth angles for the clusters directly above and below the serving cluster, i.e., in adjacent rows, are opposite that of the antenna pointing azimuth angle of the serving cluster. Furthermore, the cells contained in the serving cluster have the same antenna pointing azimuth angle as those cells within adjacent clusters to the right and left of the serving cluster, i.e., in the same row.
