A novel cell-interference depth model and performance analysis for the future wireless networks

Facing with the challenges of explosive growth in mobile traffic demands, as well as the requirements of reliable connectivity for billions of diverse devices, the wireless network architecture with heterogeneous coverage and overlapping coverage will be an important key feature. Therefore, the precise analysis of the interference property of cellular coverage becomes extraordinary necessary. A novel quantified cell-interference depth model is proposed in this paper, to study the interference property and networking performance of the future wireless networks. The proposed model can be used to describe the relationship between the interference and the cell depth entered precisely. Also we derive the mathematical expressions of the cell spectral efficiency and the energy efficiency, and analyze the achievable performance of the cellular networks numerically. These results may used as an important reference for the architecture design of the future wireless networks.
