A distance-to-radius (D/R) ratio is a parameter used to describe the reuse factor for a wireless system. The D/R ratio for any wireless system determines the reuse factor as welt as the distance between the reusing cell sites and of course the radii of the serv¬ing cell sires. Figure 4.2 and the Table below illustrate standard D/R ratios for different frequency reuse patterns, N.
D/I N (reuse pattern)
3.46R 4
4.6R 7
6R 12
7.55R 19

Its nothing but the geographical distance that is required between the calls using identical frequency to avoid interference between the radio transmissions of the cells.
