Abstract :
Wideband radiowave propagation measurements were performed within a building at 2, 5 and 17 GHz using a vector network analyser. The exponent of the path-loss law n and the statistics of the rms delay spread were evaluated for line-of-sight (LOS) and obstructed (OBS) paths. Values of n for LOS paths were similar for all three frequencies whilst increasing attenuation with frequency was observed for OBS paths. Mean rms delay spread values were found to decrease with frequency
