System-Level Performance Properties Of Millimeter Wave Multicell Networks

With the launch of the 5th generation (5G) communication services next year, the enhanced mobile broadband services are expected to become further accelerated. However, even though millimeter wave (mmWave) spectrum provides huge bandwidths, the use of such a spectrum has received less attention, compared with a sub-6GHz spectrum, e.g., 3.5GHz., due to the concern about the inherent properties of mmWave such as harsh propagation loss. Therefore, this paper evaluates the potentials of mmWave multicell systems through designing and implementing a simple yet accurate mmWave multicell simulator. The results demonstrate that the mmWave gives attractive benefits when appropriately adjusting the design parameters including the BS density, maximum number of beams, and beamwidth depending on mmWave blockage environments.
