Question

Co-channel reuse ratio is define by _________

(a) Q=D*R

(b) Q=D/R

(c) Q=D^R

(d) Q=1/R

The question was asked by my college professor while I was bunking the class.

This intriguing question originated from Interference and System Capacity in section The Cellular Concept – System Design Fundamentals of Wireless/Mobile

Answer 1

Correct answer is (b) Q=D/R

To explain: Co-channel reuse ratio is defined by Q=D/R. By increasing the ratio of D/R, the spatial separation between co-channel cells relative to the coverage distance of a cell is increased. Thus, interference I reduced from improved isolation of RF energy from the co-channel cells.
