### Introduction to Mobile SystemsCellular System Concept

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.

i=1, j=2 , N=1+2+4=7 cell, one must do the following:

Interference cell, one must do the following:

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 cell, one must do the following:
