A computer-implemented method for determining a tilt range for each
cell (300) of a plurality of cells of a
wireless cellular
telecommunications network, each
cell (300) having at least one antenna (20). The method comprises the steps of: for each
cell (300) of the plurality of cells, determining a value for each of a plurality of
metrics, the plurality of
metrics comprising: a metric indicative of retainability, a metric indicative of capacity, a metric indicative of uplink, UL, quality, a metric indicative of downlink, DL, quality, and a
cell parameter; determining respective thresholds for each metric; for each cell (300) of the plurality of cells, classifying the cell (300) into one of a plurality of categories based on a comparison of the determined values of the plurality of
metrics of the cell (300) to the corresponding thresholds, wherein each category of the plurality of categories has an associated range of tilt values; and determining, for each cell (300) of the plurality of cells, the tilt range for that cell (300) as the range of tilt values associated with the category into which the cell (300) is classified.
