“…The power delay profile (PDP) in a RC is exponentially decreasing, generally [6,12,18,46,47]. As a figure of merit to describe the PDP, the RMS delay spread τ RMS is commonly used, which can be obtained according to [10,14,39] by calculating…”

Communication reliability is a challenging requirement, which implies the need for over-the-air (OTA) testing. Reverberation chambers (RCs) are widely used for OTA tests in various fields. Due to their properties, such as inherent radio channel emulation or the arbitrary orientation of the equipment under test (EUT) in the test volume, they can be used as advantageous test environments for wireless products in the field of industrial manufacturing automation, such as for the IO-Link Wireless (IOLW) standard. In this paper, the different OTA sensitivity test procedures total isotropic sensitivity (TIS), average fading sensitivity (AFS) and mean channel packet error (MCPE) method, which is based on the fundamental channel model of the wireless standard, are described and evaluated in various variants. A core aspect of the proposal is the impact of the possible use of frequency hopping of the wireless equipment under test. The respective advantages and disadvantages are shown. Overall, TIS proves to be a suitable alternative for IOLW OTA sensitivity testing.

“…In this article, we first show that the nonregular 3-D polarization states may occur in the loaded RC and they can only be represented by means of the CP decomposition. Hence, they can be used to make more accurate field isotropy testing in the RC that, as suggested in [38], should be performed using 3-D polarimetric approaches instead of using the conventional integrated 3-D linear measurements [1]. In fact, the conventional IEC 61000-4-21 standard [1] procedure is considered to be not enough when dealing with loaded RC configurations [38].…”

Reverberating chambers (RCs) are electrically large microwave enclosures in which a random electromagnetic 3-D, i.e., nonplanar, field is generated. To characterize such 3-D fields, a proper polarimetric decomposition is requested. In this article, a new set of parameters, namely the components of purity (CP), first proposed to the electromagnetic compatibility community, is presented. The CP parameters, which stem for the so-called trivial decomposition, are able to classify any 3-D polarimetric field into two states: regular and nonregular. Such characterization is of practical relevance, e.g., for RC isotropy testing.
