ABSTRACT:
A cell pattern for use with a frequency reuse plan is disclosed. Seven clusters each comprising N cells per cluster are grouped together as a modified cluster. Each cell is further divided into three sectors. The total number of available frequency channels are divided into a F times seven (F*7) number of groups. Frequency channels associated with a group are then assigned to each of the cells within the modified cluster. In order to increase call capacity within a particular sector, a frequency channel previously assigned to a corresponding sector within the same cell group is reused. Within a continuing increase in channel re-usage within a particular modified cluster, the (N*7)/(F*7) reuse plan is gradually lowered to the original N/F reuse plan without re-configuring the frequency allocation throughout the network.
