Abstract

This paper presents a method of directional frequency reuse for high density, high capacity cellular networks. Unlike the classical method of cluster reuse, the proposed directional frequency reuse is based on group reuse, having multiple reuse distances. Consequently, the carrier to interference ratio (C/I) appears as a function of multiple reuse distances with fewer cochannel interferers. Moreover, antenna downtilt and beamwidth becomes more effective thus enhancing C/I and capacity. These novel features are presented in this paper
