a method for generating a plot of cell towers and associated sectors on a map includes the steps of determining a position of at least one cell tower on a map responsive to data indicating a position of the cell tower and determining boundaries associated with a plurality of sectors associated with the at least one cell tower responsive to an azimuth associated with each of the plurality of sectors . a location of call events are also determined responsive to call data . a plot of the map is generated including the at least one cell tower , the boundaries associated with the plurality of sectors associated with the at least one cell tower and the location of the call events marked on the map .
