Path loss analysis for terahertz band single-lane vehicular communication

The Terahertz (THz) band lies between the millimeter wave and the far infrared band (0.1-10 THz) and has an important potential for 5G and 6G communication systems. It is a band gap open to future research as it has not been sufficiently explored. The THz band promises an ultra-high data rate and capacity. Considering vehicular communications, the rapidly increasing data traffic is excessive for current vehicular communication technologies to handle. New technologies and approaches are thus needed to deliver higher capacity and data rates with lower latency. Therefore, it is acknowledged that THz technology is a promising technology that can meet these requirements. In this study, the propagation of the THz signal in single-lane vehicular communication was examined. Respective path loss analyses were performed using the High-Resolution Transmission Molecular Absorption Database (HITRAN). The obtained results were compared with the measurement results in the existing studies. The effect of reflections on the path loss results of the system was also investigated. © 2023 IEEE.
