Before revision: Consider a countably infinite collection of coupled queuesrepresenting a large wireless network with a queue  at each point of the d-dimensional integer grid . These queues have independent Poisson arrivals, but are coupled through their service rateswhich is the signal to interference ratio of wireless network theory.
