Feasibility of Mobility for Millimeter-Wave Systems Based on Channel Measurements.

Fifth generation mobile networks will be designed to utilize the benefits of the large available bandwidth in the mmWave spectrum. Commercialization of 5G mmWave technology will be launched soon, due to progress in RF hardware and large efforts on integration of mmWave beamforming technologies in standardization bodies such as 3GPP. The main challenges of mmWave mobility in 5G result from the impact of fast-varying channels on beamforming systems. However, the corresponding feasibility has not yet been fully investigated. In this article we first identify and review the technical challenges that remain in 5G mmWave mobile networks. We then present sample measurements of outdoor mmWave channels, and emulate the mobile system operation in them. We discuss insights, based on these results, on under what circumstances supporting mmWave mobility is feasible. [ABSTRACT FROM AUTHOR]
