Abstract
This paper reports the results of extensive measurements and analysis of the temporal variations of indoor radio propagation channel as a result of human traffic. The broadband measurements presented were taken at 5.2 GHz and were carried out in a large laboratory environment. Four antenna configurations were considered: for three sets of measurement the receiver used an omni directional antenna while at the transmitter omni, 60" and 90" antennas were employed. The fourth arrangement used a pair of 90" antennas at the transmitter and receiver. The measurements also considered the performance of a multi-rate QPSK modem in terms of bit errors measured in the presence of human shadowing. The statistics of the received signal power, RMS delay spread and Rician K- factor are compared for the shadowing and static channel conditions.Keywords
