Network Planning and Performance Analysis for 5G mmWave in Urban Areas

Abstract

The millimeter wave (mmWave) 5G technology has a frequency with a wavelength between 1–10 millimeters and large bandwidth of 1 GHz., which can cope with the demand for capacity due to increasing cellular users. Therefore., to assist in implementing the 5G mmWave network., this paper conducts network planning for the 5G mmWave in urban areas using two Base Transceiver Stations (BTS) for macrocells. In the planning., we consider five scenarios based on 8,16, 32, 64, 128, and 256 antennas and a hybrid beamforming technique consisting of analog and digital beamforming. Furthermore., the link budget is analyzed to determine the received power and bit rate at the micro base station (BTS) from macro-to-micro BTS transmission and the user equipment (UE) from micro BTS-to-UEs transmission to evaluate the performance of the planned network. The simulation of the planned network has been conducted., and the results show that the large number of antennas used on both the transmitter and receiver sides., the greater the receiving power and bit rate. Besides that., the signal-to-interference-plus-noise ratio (SINR) strength for two cases (64 and 256 element antennas) also achieves the highest SINR, which reaches 22 dB.
