  1. Cellular System Cellular concept Propagation models

  2. Introduction to Mobile SystemsCellular System Concept

  3. The factor N is called the cluster size and is givenN=i2+ij+j2

  4. 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.

  5. i=1, j=2 , N=1+2+4=7

  6. Interference R - the radius of the cell D - the distance between centers of the nearest co-channel cells Q - the co-channel reuse ratio

  7. Table 1. Co-channel reuse ratio, S/I for some values of N

  8. Decreasing the co channel interference - sectorisation

  9. Decreasing the co channel interference - sectorisation Table 2. Co-channel reuse ratio, S/I for values of N=7 using sectorial structure
