We develop approximate asymptotic characterizations of the performance of large heterogeneous wireless networks. We consider the impact of location, traffic, and service heterogeneity. The common approach to deal with these heterogeneities consists of first finding the underlying “coarse structure'” of the network, capturing the essential parts of the heterogeneity. Once such a simple coarse structure is identified, rather complicated questions about the network can be elegantly analyzed by recasting them for the underlying coarse structure. Moreover, this coarse structure allows us to obtain insight into the role of interference or cooperation in large networks and can guide the design of communication schemes and algorithms.
