Abstract :
Results from ray-tracing modelling and measurements of RMS delay spread in indoor line-of-sight (LOS) environments at HIPERLAN/U-NII frequencies (5.2 GHz) with omni-directional antennas have shown that the maximum RMS delay spread in a room is dependent on the dimensions of the room and the reflectivity of the walls. Under these conditions the RMS delay spread increases with distance from the transmitter up to a maximum value that is thereafter constant with distance over the remainder of the room
