Geometric Criteria to Improve the Interference Performances of Cellular Network

Networks based on cellular concept suffer of bad performance when calls are done during handoff, i.e. during the transfers from one cell to another one. A part of these bad performances are due to the lack of management of overlapping area between cells. These imperfections find expression in cells discontinuity and distortion, in irregularity on inter-antenna distances, and in cells size variation. In this paper, we present several new criteria for cellular networks optimization based on geometrical computation on handoff and interference zones. The relevance of the model is studied on the basis of numerical and visual appreciation accorded to different networks. The huge impact of cell geometry improvement on radio quality of the network will be also discussed.
