“…It is straightforward to measure total radiated power (TRP) in the reverberation chamber, and it has been shown in several papers that BERs also can be measured if the chamber is appropriately loaded, so that the coherence bandwidth becomes similar to the real-life environment we want to emulate [25], [26]. Here, we briefly describe how these measurements are done, and in Section VIII, we will extend the latter BER measurements to data throughput measurements, and present a simple good theoretical model for the same.…”

Use of a reverberation chamber for testing wireless devices in rich isotropic multipath environments is discussed in this paper; a theory for accurately modeling measured throughput is presented.ABSTRACT | New over-the-air (OTA) measurement technology is wanted for quantitative testing of modern wireless devices for use in multipath. We show that the reverberation chamber emulates a rich isotropic multipath (RIMP), making it an extreme reference environment for testing of wireless devices. This thereby complements testing in anechoic chambersrepresenting the opposite extreme reference environment: pure line-of-sight (LOS). Antenna diversity gain was defined for RIMP environments based on improved fading performance. This paper finds this RIMP-diversity gain also valid as a metric of the cumulative improvement of the 1% worst users randomly distributed in the RIMP environment. The paper argues that LOS in modern wireless systems is random due to randomness of the orientations of the users and their devices. This leads to the definition of cumulative LOS-diversity gain of the 1% worst users in random LOS. This is generally not equal to the RIMPdiversity gain. The paper overviews the research on reverberation chambers for testing of wireless devices in RIMP environments. Finally, it presents a simple theory that can accurately model measured throughput for a long-term evolution (LTE) system with orthogonal frequency-division multiplexing (OFDM) and multiple-input-multiple-output (MIMO), the effects of which can clearly be seen and depend on the controllable time delay spread in the chamber.

“…The antenna spacing was greater than one-half wavelength (the wavelength is 0.125 m at 2.4 GHz). We tested a digitally modulated signal that utilized binary phase-shift keying (BPSK) by use of the method of [12]. In this method, no standardized transmission access scheme or error correction was used, in order to evaluate the most basic form of the received signal.…”

Abstract-We present a general method for over-the-air test of antenna setups and/or post-processing algorithms used in advanced transmission schemes. The method utilizes a reverberation chamber to simulate various levels of multipath in the propagation environment. Multipath is essential for correctly estimating the performance of multiple-antenna systems. Our test set-up enables measurement of data throughput with standard laboratory instruments. With this test set-up, antenna setups can be studied while isolated from any specific system hardware implementation.Index Terms-antenna array, antenna diversity, beam forming, bit error rate, multipath, multiple-input, multiple-output wireless system, reverberation chamber, wireless system.

We develop methods for assessing the component of measurement uncertainty arising from various combinations of mode-stirring techniques in reverberation-chamber measurements. We first develop a components-of-variance model that describes this component of uncertainty in terms of physical mechanisms related to the chamber. We illustrate the use of the model in conjunction with measurements to identify the optimal modestirring sequence for a measurement of received power.
