毫米波（mmWave）频谱为未来的蜂窝系统带来希望。MmWave蜂窝部署可能是密集的，以实现良好的覆盖。本文提出了一种简化的方法来评估密集毫米波网络的覆盖概率。通过简化一个框架，包括阻塞，解析表达式推导出计算的覆盖概率。结果表明，在密集网络中，要保持相同的覆盖概率，小区的平均大小应与视距区域的平均大小成比例，最佳基站密度应足够密集，但不能太密集。
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.
