2-2Cell Site Configurations

Figure 2-1 shows the layout of an Omni (N=7) frequency reuse plan;. The RF channels used in Cell 1 of a cluster are reused in Cell 1 of other clusters, channels in Cell 2 are reused in Cell 2 of other clusters and so on.

CELL 1

120° sectorized configuration

In a 120° (N=7) sectorized configuration, the 416 RF channels are divided among a cluster of seven cells. Each cell contains a maximum of 59 or 60 RF channels, with three Control channels for each cell. Since each cell is further divided into three sectors, each sector will contain a maximum of 19 or 20 RF channels, with one Control channel for each sector. The available RF channels are reused by other groups of cells within the system.
