The Effects Of Different Weather Conditions On 5G Millimeter Waves Propagations at 38 GHz and 73 GHz For Kut-City in Iraq

Abstract

It is critical to utilize a good model for predicting acceptable and optimum frequencies while designing and planning for the future generation wireless communications system's channel. This paper explains how the weather conditions affect the strength of the transmitted signal in various environments and circumstances, as well as how the mmWave behaves as it passes through free space and the atmosphere. An NYUSIM simulator package is used for predicting the performance of the channel for two months (January and July). Two frequencies were used, 38 GHz and 73 GHz to test the channel performance and which frequency is the best suited for the Kut city environment. The simulation results shown that an agreement with the 38 GHz for its lower path loss and acceptable received power. The weather database was real and actual obtained from the Iraqi meteorological organization and seismology reports consist of (rain, fog and temperature). The result for both directional and omnidirectional power delay profile showed a great agreement at 38 GHz for the two months (January and July), where the path loss and received power at 38 GHz for January is 127 dB and -47.2 dBm respectively, where for 73 GHz the path loss is 135.4 dB and with a received power of -55.7 dBm. At July the path loss and received power for 38 GHz and 73 GHz is (123 dB, -43.2 dBm) and (130 dB, -43.2 dBm) respectively.
