“…The RC offers a cost-effective and efficient OTA testing solution, and has been standardised for OTA tests of large-form-factor devices [9]. It was used to study the performance of orthogonal frequency division multiplexing (OFDM) in highly dispersive environments [10]. Recently, it has been used for testing carrier aggregation of a real base station [11].…”

Due to the explosive increase of wireless devices, efficient over‐the‐air testing of such devices is highly desirable. The reverberation chamber (RC) offers efficient and cost‐effective means to determine performance metrics of wireless devices, such as total radiated power (TRP). In this study, the distribution of the measured TRP in an RC is analytically derived, based on which the statistics (i.e. mean, variance) of the measured TRP are derived as well. RC measurements have been performed to verify the analytically derived statistics.

“…Deploying wireless networks in confined, reflective spaces such as found in metallic warehouses, aircraft cabins, and below-deck compartments in ships is gaining lots of interest, mainly for automatic alarm, monitoring, and safety applications. In particular, below-deck spaces in ships have been a primary focus of a number of studies, which explored both RF propagation and wireless communication performance [1]- [5]. Current shipboard monitoring systems use extensive lengths of cables to connect a massive number of sensors to control units.…”

“…In addition, ships represent a harsh environment in which wires are vulnerable to moisture, heat and toxic elements, making maintenance a very difficult task. On the other hand, wireless communication is a serious challenge in the particular environment of ships [5]. Such highly reflective environment is characterized by rich electromagnetic scattering, time and angular dispersion, and can exhibit features of a complex reverberant cavity.…”

The theory of room electromagnetics provides a simple characterization of indoor microwave propagation. By considering the indoor environment as a lossy cavity, the exponential decay rate of the power-delay profile is related to the total absorption inside the room. In this paper, we explore the possibility of estimating the number of people inside a below-deck ship compartment using only the decay time constant, also known as reverberation time. First, we verify the reverberating nature of the room. Then, we find the relation between reverberation time and the number of people inside the room. We show that it is possible to estimate the number of people with a good accuracy, depending on the number of antennas used. With a success rate of 88%, the estimation error is only 1 person when 16 spatially averaged antennas are used.

“…Next to their EMC applications, reverberation chambers (RC's) are often used for wireless communication, such as the testing of wireless communication (MIMO) devices under a realistic channel model [1]- [8]. Among other applications these methods often make use of loading the chamber, thereby changing the power-delay profile (PDP) of the room to simulate real-life scattering environments.…”
