Efficient experimental path loss exponent measurement for uniformly attenuated indoor radio channels

Abstract

An efficient scheme is proposed for experimental measurement of path loss exponent in uniformly attenuated indoor radio channels (lognormal channels with fairly constant log-normal standard deviation). Basically, the scheme suggests proper transmitter (TX) regions to efficiently characterize the radio channel through measurement. The selection of TX locations is based on the statistical analysis of the received signal strength (RSS) derived from a rough pre-model. In this work Seidel-Rappaport site-specific models considered as the pre-model. In this work Seidel- Rappaport site-specific models considered as the pre-model. Experimental results show that the generated statistics of the RSS help select representative TX locations and reduce the number of required measurements accordingly.
