Optimization of Cellular Networks Capacity and Densification An Analytical approach

摘要

We propose an analytical approach of cellular networks, which allows to optimize transmitting powers of base stations, and to maximize network capacity. In our framework, mobiles are considered as a continuum. Networks are often densified i.e. new base stations are added because of increasing traffic. Our approach enables to analyse the extra capacity offered by each new base station, according to its location. It can be performed without any simulation whatever the model used for the propagation. The continuous approach proposed in this paper can be applied to any frequency reuse 1 networks, such as OFDMA or CDMA ones. As an example, we calculate the maximum number of active mobiles per cell in a homogeneous network, considering different kinds of environments, and we show how to optimize the densification of a network.
