Simulation and Analysis of 2.4 GHz Propagation in a Medium-Size Conference Room

Although much work has been done on characterizing indoor RF propagation, some applications require a better understanding of such behavior within the confines of a single room. In this paper, we study a medium-size conference room using a ray-tracing model. A single specific room geometry is simulated but multiple narrowband realizations are obtained over a range of frequencies centered at 2.4 GHz. The resulting responses, are analyzed in terms of impulse response, rms delay spread, frequency response, coherence bandwidth, spatial correlation, and condition number. This analysis provides insight for explaining features of the data and guidelines for implementation requirements. The results quantify the often stated notion that inside a single room, the propagation is Rician-like, with the direct path stronger than the reverberation by a factor depending on the frequency realization and receiver location.
