We propose a new framework to study the performance of cellular networks using a fluid model and we derive from this model analytical formulas for interference outage probability and spatial outage probability. The key idea of the fluid model is to consider the discrete base station BS entities as a continuum of transmitters that are spatially distributed in the network. This model allows us to obtain simple analytical expressions to reveal main characteristics of the network. In this paper we focus on the downlink other-cell interference factor OCIF which is defined for a given user as the ratio of its outer cell received power to its inner cell received power. A closed-form formula of the OCIF is provided in this paper. From this formula we are able to obtain the global outage probability as well as the spatial outage probability which depends on the location of a mobile station MS initiating a new call. Our analytical results are compared to Monte Carlo simulations performed in a traditional hexagonal network. Furthermore we demonstrate an application of the outage probability related to cell breathing and densification of cellular networks.
