In cellular network models, the base stations are usually assumed to form a lattice or a Poisson Point Process (PPP). In reality, however, they are deployed neither fully regularly nor completely randomly. Accordingly, in this paper, the authors consider the very general class of motion-invariant models and analyze the behavior of the outage probability (the probability that the Signal-to-Interference-plus-Noise-Ratio (SINR) is smaller than a threshold) as the threshold goes to zero. They show that, remarkably, the slope of the outage probability (in dB) as a function of the threshold (also in dB) is the same for essentially all motion-invariant point processes.
