Comparative study of 900 MHz and 450 MHz radio signals propagationin an indoor environment

摘要

The results from propagation measurements, conducted in an indoorbuilding environment at 900 and 450 MHz are presented. The distancedependance of the received signal power in an LOS condition along thecorridor of the second floor of an institute building was obtained. Theindoor channel characteristics for the two frequencies are compared byan evaluation of the experimental and simulated received signal power.The computer simulated data were obtained for the RMS delay spread andcoherence bandwidth
