Abstract
In this chapter, we cover some of the key issues related to the use of heavily loaded reverberation chambers for OTA testing of wireless device performance. Specifically, we address cases where the communication signal is spread over a wide modulation bandwidth and must be demodulated and cases in which a particular power delay profile is to be replicated. Metrics used to characterize the chamber configuration, such as the reference power transfer function, spatial uniformity, isotropy and chamber decay time are not significantly different from those used in prior work of the EMC/EMI community. However, their application to the case where significant correlation exists between frequencies and spatial samples requires additional consideration. As such, we pay a great deal of attention to the assessment correlation and its impact on uncertainty in the estimate of power-based metrics such as TRP or TIS.Citation
