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