Heterogeneous Cellular Network Analysis

This chapter generalizes the downlink results to the case of a heterogeneous cellular network (HetNet), where different classes of base-stations are present in the network. Deploying small cells overlaid on an existing wide area macrocell network is a key direction in ongoing and future cellular network deployments, so this is an important but nontrivial generalization, and one that has gained considerable popularity for the stochastic geometric approach. Overall, the outlook for densification with small cells is quite bright in light of the results of Chap. 4.
