Experimental power transfer and signal assessment of wireless communications in reverberating cavities

This paper focuses on experimental measurement of power and signal transfer of wireless communication in reverberating cavities. The experiment is based on the evaluation of a transfer function between two antennas placed inside and outside a confined reverberating environment made of several metallic cavities. Inside these cavities, a WIFI communication is used in order to control the measurement setup in order to take advantage of its simple connection with the measurement devices. Therefore the first exploitation of this experiment is directly to measure S-parameters as main parameters for characterizing this transfer functions. The second type of exploitation consists in the assessment of the integrity of the WIFI communication in such a closed and confined reverberating environment.
