N2 - The room electromagnetics (RE) theory describes<br/>the radio propagation in a single room assuming diffuse scat-<br/>tering. A main characteristic is the exponential power-delay<br/>profile (PDP) decaying with the so-called reverberation time (RT)<br/>parameter, depending only on the wall area, the volume of the<br/>room and an absorption coefficient. The PDP is independent<br/>on the location in the room, except for the arrival time. Based<br/>on measurements in a room with a spherical array of 16 dual-<br/>polarized wideband horn antennas, the current work studies<br/>how the RE parameters depend on the receiver (Rx) antenna<br/>polarization and orientation. Also the frequency dependence<br/>is investigated, with measurements done at both 2.3 GHz and<br/>5.8 GHz center frequencies. The RE theory was found to fit well<br/>to the measurements with a RT in the range 22-25 ns. Only small<br/>differences were found due to the polarization and the channel<br/>gain was depending approximately as expected with frequency.<br/>
