Abstract

Terahertz (THz) communication has been suggested as a key enabling technology of sixth-generation wireless networks due to its high data rates and low latency. The investigation of THz channel performance under various atmospheric conditions, such as snow, haze, rain, fog, dust, sand, and various gases, is critical. In this paper, we considered the impact of atmospheric gases on THz channel performance. The THz channel path loss is estimated and compared using Close-In (CI), Close-In frequency (CIF), and Alpha-BetaGamma (ABG) path models for THz frequencies ranging from 300 GHz to 400 GHz and a propagation path of 1 km distance. The atmospheric effects considered in this paper are dry air and water vapor. The simulation results show that the CI and CIF models show higher path loss than the ABG model, because the CI and CIF models depend on the environment’s physical characteristics. The CI, ABG, and CIF models estimate the path loss for environmental effects and the absorption due to dry air and water vapor. Using the CI model, the path loss of 506 dB and 370 dB is observed without and with the atmospheric attenuation. Using the CIF and the ABG model, the path loss of 351 dB, 335 dB, 297 dB, and 220 dB is observed without and with the atmospheric attenuation, respectively. Hence, the simulation results indicate that atmosphe
