The millimeter wave (mmWave) spectrum holds promise for future cellular systems. MmWave cellular deployments are likely to be dense to achieve good coverage. This paper proposes a simplified approach to evaluate the coverage probability in dense mmWave networks. By simplifying a framework that incorporates blockages, analytical expressions are derived to compute the coverage probability. The results show that the average cell size should scale with the average size of the line-of-sight region to maintain the same coverage probability in a dense network, and that the optimum base station density should be dense enough but not too dense.
