    <description descriptionType="Abstract">&lt;p&gt;The fifth generation (5G) network needs to evolve in order to increase the capacity 1000 times higher than the fourth generation of networks by 2025. Small cells (Dense Nets), millimeter wave (mmW) and massive multiple-input multiple output(MIMO) deployment have emerged as key technologies for mobile systems in fifth generation (5G).However, less study have been done on combining the three technologies into the existing systems. In this paper, we provide an in-depth capacity analysis for the integrated Dense Nets mmW systems. First, small cells are deployed on the top of single macro cell scenario for enhance the capacity. Instead, by extending the blockage models; a simpler mmW channel is implemented. It turns out that mmW signals are responsive to blockage, leading the LOS and NLOS conditions to have very different PL rules. In addition, they divide the power research into low signal-to-noise (SNR) and high SNR regimes based on dominant signal-to-interference factors plus the noise ratio. In noise-dominated (high-SNR regime), the capacity analysis is derived by simplest assumptions of Shannon Hartley theorems. Our results show that, under NLOS and LOS scenario, mmW frequency and distance between UE and BS decreases logarithmically for system capacity. In addition, the results show that densification is also essential to allow channel capacity through MIMO and increase the SNR in the term of through the antennas. Finally, the results of the computer simulation validate the theoretical analysis and show that the integrated Dense Nets mmW systems can achieve significant capacity improvement.&lt;br&gt;
