Measurement and Analysis of Radio Signal Propagation in and from Corridor at 300 GHz

To realize the potential of the Terahertz band (0.1 - 10 THz) in providing high data rate, low latency, and improved reliability extensive measurement campaigns are the need of the hour. In this context, the current study presents the results from a first-of-its-kind measurement campaign conducted in a corridor and from corridor to room at 300 GHz. The investigated positions consist of both line-of-sight and non-line-of-sight cases. The measurement data is processed to generate the power delay profile and environment-embedded azimuth delay power spectra for the positions under study. A careful analysis of the generated results helps in identifying the dominant specular components for each position using ray tracing. We further confirm the poor penetration property of signals at 300 GHz through regular building materials like concrete and plasterboard. The current results lay the foundation for more extensive analysis to develop a channel model for one of the common yet unexplored indoor scenarios.
