Path Loss Exponent Modeling for 6G Applications at 245 GHz

This research investigates the modeling of path loss exponent in an indoor environment at sub-Terahertz (THz) frequencies. The study examines directional and omnidirectional propagation characteristics within an indoor environment at 245 GHz, considering line-of-sight (LOS) and Non-LOS (NLOS) scenarios. Simulations were conducted using the Wireless InSite (WI) software, employing the shoot and bouncing rays (SBR) technique. The received signal strength (RSS) and path loss (PL) recorded during these simulations were comparatively validated against results from the WinProp software, utilizing the dominant path model (DPM). The findings demonstrate a strong agreement between the two techniques.
