Coverage in Dense Millimeter Wave Cellular Networks

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.
