A recent study has conducted a large-scale analysis of 18 GHz electromagnetic wave propagation in indoor environments, specifically within a corridor. The research focused on characterizing line-of-sight (LoS) and non-line-of-sight (NLoS) conditions, which are fundamental for the development of next-generation wireless communication systems. This work provides crucial empirical data for the accurate modeling of channels in millimeter and sub-millimeter frequency bands, key for technologies like 5G and future 6G.

The study employed a systematic approach, performing detailed measurements of received signal power and other channel parameters at multiple locations within the corridor. Directional antennas were used to simulate realistic transmission and reception scenarios, capturing the complexity of propagation in an environment with obstacles and reflections. The results obtained allow for a deeper understanding of how 18 GHz waves interact with architectural structures, clearly differentiating behavior in LoS and NLoS conditions.

The findings of this research are highly relevant for communications engineering. By quantifying signal attenuation, dispersion, and channel variability under different conditions, the study offers a solid foundation for designing more robust and efficient signal processing algorithms, as well as for optimizing antenna placement and network planning. This data is essential for overcoming the challenges associated with high frequencies, such as increased sensitivity to obstacles and the need for advanced beamforming techniques.
