A Semi-Reverberation Chamber Configuration to Emulate Second-Order Descriptors of Real-Life Indoor Wireless Propagation Channels

A Fast Procedure for Total Isotropic Sensitivity Measurements of Cellular IoT Devices in Reverberation Chambers

“…The method presented in this paper takes advantage of faster continuous-mode measurements (in comparison to stepped-mode ones) and the use of devicereported received power levels to expedite the determination of the TIS. In addition, continuous stirring maximizes the number of field configurations the DUT is exposed to during the tests [16,17], not restricting the experiment to a pre-defined finite set of stirring mechanisms' configurations. Another key feature is that the measurement samples are collected at high receivedpower levels, resulting in a high SNR for much of the data.…”

A mm-Wave Hybrid Stirring Technique for Over-the-Air Testing in Reverberation Chambers

“…To address this issue, attempts are done to develop a hybrid chamber that exhibits characteristics of both AC and RC. A reverberation chamber is chosen as the starting point in these studies, and is selectively loaded with RF absorbers to emulate a directional channel within [13]- [15]. Nevertheless, the full control of temporal and angular characteristics of the channel is not accomplished yet.…”

“…To gain more control over the directionality of the emulated channel, the spatial uniformity of the conventional reverberation chamber should be broken down in a controlled manner. In contrast to the previously proposed hybrid chambers that which large blocks of RF absorbers are used to load the chamber [13]- [15], two novel loading configurations are investigated for this aim. In the first configuration, the RF absorbers are placed on the stirrers to achieve a tuneable, half-absorbing structure instead of the commonly used fully-reflective ones.…”
