Experimental evaluation of downlink transmission and beam tracking performance for 5G mmW radio access in indoor shielded environment

This paper presents experimental results on downlink transmission and beam tracking performance in an indoor shielded room environment using a Proof-of-Concept (PoC) system targeting 5G millimeter wave (mmW) radio access. Experiments in mmW targeting under mobility and beam tracking with narrow beams in reflective environment have not yet been conducted. The mmW transceiver is implemented with analog beamforming using a switched feeder array and a dielectric antenna. The experimental results show that a throughput of greater than 2 Gbps is achieved while employing beam tracking and a lens antenna. Furthermore, the performance in an anechoic camber was also evaluated. We conclude that the indoor shielded room has low reflections comparable to an anechoic chamber when using the mmW transceiver.
