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.
