A Statistical Investigation of Spatial Consistency and Human Blockage Consideration based mmWave Channel Modeling for 5G Back-Haul Networks

Due to its broad (10-300 GHz) spectrum and potential for widespread use in 5G applications, millimeter wave (mmWave) technology is proposed as an alternative to optical fiber for backhaul. However, human blockage as well as rapid channel fluctuation caused by user movement are two of the biggest obstacles to mmWave communication implementation in the network. Spatial consistency is one of the most crucial factors for achieving smooth channel fluctuations and contributing in the design of channel estimation and beam tracking. This paper investigates a clear understanding of how human blockage and spatial consistency affect the reliability of 5G mmWave backhauling in real-life scenarios for an urban macrocell (UMa) of busy airport areas. An extensive simulation on mmWave backhauling considering 28 GHz and 60 GHz mmWave has been carried out which will significantly affect the channel modeling of next-generation complex communication networks.
