Abstract
Current and emerging indoor radio communications systems are designed to operate at microwave frequencies and above. As frequency is increased, fading effects caused by the movement of personnel become more significant over short-range channels. This paper examines pedestrian-induced fading characteristics at key ISM frequencies within the microwave band. Consideration is given to the effects of wave obstruction by the human body - reflection, diffraction and transmission. Fading profiles are reported for a point-to-point link in a 150-m2 open-plan environment with moderate pedestrian traffic conditions. Irrespective of simulation frequency, the calculated fading profiles were loosely correlated and fading depths ranged between 31-dB and 36-dB. The results were Rayleigh distributed despite the presence of a direct-ray for the majority of the simulated period.
