Multipath propagation environment effects, such as frequency-selective fading, have a strong impact on the quality of the wireless channel. For example, multipath can impact bit error rate (BER) differently than Gaussian noise. For testing wireless devices/systems in these multipath environments it is imperative to have a reliable, controllable, and statistically repeatable measurement facility. The purpose of this paper is to illustrate how the reverberation chamber can be used to simulate different multipath propagation environments. Channel characteristics, such as power delay profile, RMS delay spread, and the Rician K-factor are examined. Results for different chamber configurations (e.g., loading of the chamber, antenna positions, etc.) are compared and their effects are discussed. Results achieved inside a chamber are compared with those obtained in an actual industrial environment.
