Cellular communications system

摘要

The invention relates particularly to fixed wireless access networks and provides a cellular communication network which serves directional subscribers while reducing co-frequency interference substantially uniformly across the network. The network comprises a plurality of base stations arranged to form sectored cells using a plurality of carrier frequencies, where sectors carrying common frequencies are directionally mis-aligned and arranged such that the polarization of said frequencies are varied with respect to each other across the network in order to reduce co-frequency interference.
