- Abstract
- Most indoor propagation studies have primarily focused on office environments. In this study, however, we investigate indoor propagation characteristics for conference and lecture room environments, which are relevant for applications such as hybrid meetings, digital classrooms, etc. Using 159-GHz rotational scanning measurements, we derive both the best directional and the synthesized omnidirectional path loss and delay spread characteristics. These results are compared with other environments, such as office and corridor ones. Our measurement data show that the path losses in the lecture room are higher than in the conference room, particularly for NLoS links. In terms of delay spread, the conference room shows similarities to office measurements, likely due to comparable dimensions. Unlike in the corridor environment, the path loss exponents for LoS and NLoS in the conference and lecture rooms are not significantly different, indicating that NLoS obstructions from pillars do not cause significant attenuation compared to corner turns.
