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

We study RF propagation in a medium-size conference room using the WiSE tool, which is a ray tracing model that has been developed for designing indoor wireless communication systems. 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, which form a useful 802.11b database in such environments, are analyzed in terms of impulse response, rms delay spread, frequency response, coherence bandwidth, spatial correlation, and condition number. This analysis provides validation, insight for explaining features of the data, and guidelines for implementation requirements. A key finding is that inside a single room, the propagation is Rician-like, with the direct path stronger than the reverberation by 0 to 16 dB, depending on the frequency realization and receiver location.
