Abstract. The results of local positioning by means of received signal strength value detection in wireless nets of IEEE 802.15.4 type are presented. The main attention is devoted to the problem of positioning inaccuracy depend on multipath signal propagation. The comparison of real experiment measurements and numerical simulation data are in the center of discussion.
