High capacity cell planning based on fractional frequency reuse with optimum trunking efficiency

The fractional frequency reuse plan organizes available frequencies into 16 frequency groups. This group of frequencies is then reused in such a way that three adjacent reuses of a frequency group forms an apex of a triangle. Each reuse on the triangle appears as back-to-back, radiating in different directions, 120° apart. This frequency reuse plan generates an N=5.333 tri-cellular plan, providing 30% more capacity than the conventional N=7 sectorized system
