What is frequency reuse ratio?

15. What is frequency reuse ratio?

If the cell size and the power transmitted at the base stations are same then co-channel Interference will become independent of the transmitted power and will depend on radius of the cell (R) and the distance between the interfering co-channel cells (D). If D/R ratio is increased, then the effective distance between the co-channel cells will increase and interference will decrease. The parameter Q is called the frequency reuse ratio and is related to the cluster size. For hexagonal geometry
Q = Distance b/w Centers of the nearest co – channel cells/Radius of the cell
From the above equation, small of `Q' means small value of cluster size `N' and increase in cellular capacity.
