Abstract

In this paper we present the results of a statistical analysis of the wireless radio channel in indoor home scenarios\nat 2.4 GHz frequency. This study focuses on developing an empirical path loss model for 802.11n network. The work is\nbased on an extensive set of received signal strength (RSS) measurements collected within different typical indoor spaces\nscenarios. A frequency domain based experiment is performed for line-of-sight (LOS) and obstruction propagation\nconditions. A measurement of signal level within indoor environment is done without presence of people movement. The\ncharacterization of the path loss exponent and the reference path loss are provided. The measurement aims was to find\nempirical parameters to wireless channel models. Results are compared with corresponding values from the log-distance\nmodel, which is most widely used in wireless networks. The analysis reveals interesting regularities within the measured data\nand expected we observe a highly non stationary behaviour of the RSS.
