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

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