Nortel Networks 411-2021-111 manual 120 N=7 sectorized frequency reuse plan

Cell Site Configurations 2-3

Figure 2-2 shows the layout of a 120° (N=7) sectorized 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. This arrangement will have the RF channels using the same carrier frequency in different areas to be separated from one another by the greatest possible distance to minimize co-channel interference.

However, sectorization (by virtue of the modified coverage areas and directional antenna usage) permits greater reuse of frequencies for a given C/I ratio.
