Spatial Outage Probability for Cellular Networks

In this paper, the authors propose a new framework for the study of cellular networks called the fluid model and they derive from these model analytical formulas for interference, outage probability, and spatial outage probability. The key idea of the fluid model is to consider the discrete Base Stations (BSs) entities as a continuum of transmitters which are spatially distributed in the network. This allows people to obtain simple analytical expressions of the main characteristics of the network. In this paper, they focus on the downlink other-cell interference factor, f, which is defined here as the ratio of outer cell received power to the inner cell received power.
