Analysis of radio wave propagation from an indoor hall to a corridor

In this paper the radio wave propagation from an indoor hall to a corridor was studied by analyzing the results from a multi-link MIMO channel sounding measurement. The results showed that despite NLOS conditions, the dominant propagation mechanisms comprised direct path through the wall and specular reflections. These findings were verified by plotting the dominant pathways with a measurement-based ray tracer. In contrast to what was expected, the wave-guide propagation around the corner had almost negligible effects in this case. The results indicate that indoor localization and navigation applications using the direction or the delay of the first arriving path can be possible even in NLOS scenarios.
