The factor N is called the cluster size and is givenN=i2+ij+j2
To find the nearest co-channel neighbor of a particular cell, one must do the following: • move i cells along any chain of hexagons and then • turn 60 degrees counter-clockwise and move j cells.
Interference R - the radius of the cell D - the distance between centers of the nearest co-channel cells Q - the co-channel reuse ratio
Decreasing the co channel interference - sectorisation Table 2. Co-channel reuse ratio, S/I for values of N=7 using sectorial structure
