Abstract

A method for optimizing spectral re-use between an interferer cellular system and a desirable cellular system is disclosed wherein an acceptable baseband signal to interference ratio (SIR) is determined, and an interference reduction factor (IRF) is determined. The ratio of the SIR to the IRF is determined, and the fourth root of the determined ratio is determined, which fourth root represents the optimal minimum ratio of the distance of a mobile unit from an interferer cellular system to the distance of the mobile unit from a desirable cellular system.
