Field Experimental Evaluation of Low SHF 5G Radio Access System Employing Higher Rank MIMO

This paper presents field experiments on the downlink throughput performance of a 5G centimeter wave radio access system employing higher rank MIMO in a shopping mall environment and a long corridor environment. The shopping mall has complex reflection paths within its non-line-of-sight areas. The long corridor environment exhibits line-of-sight propagation with many reflection paths. The results show that the maximum throughput of more than 4.8 Gbps in downlink is achieved with 400 MHz spectrum bandwidth in 20% of the course in the shopping mall environment. Moreover, the maximum Rank-8 transmission of more than 9.6 Gbps in downlink can be achieved in the long corridor environment.
