ABSTRACT:
The fractional frequency reuse plan groups available frequencies into 16 frequency groups. These frequency groups are then allocated to a group of sectors such that a four by four matrix results. The top two rows of the matrix are alternating odd numbered frequency groups while the bottom two rows of the matrix are alternating even numbered 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 direction, 120.degree. apart. This frequency reuse plan generates an N=5.333 system.
