The millimeter wave (mmWave) band offers the potential for high bandwidth communication channels in cellular networks. It is not clear, however, whether both high data rates and coverage in signal-to-noise-and-interference ratio can be achieved in interference limited millimeter wave cellular networks due to difference in propagation conditions and antenna topologies. This article shows that dense mmWave networks can achieve comparable coverage and significantly higher data rates compared with conventional microwave networks. Sum rate gains can be achieved using more advanced beam- forming techniques that allow multiuser transmission. The insights are derived using a new theoretical network model that incorporates key characteristics of mmWave networks.
