SYSTEMS AND METHODS FOR REAL-TIME LOCATION

Torna indietro

Abstract

An embodiment concerns the field of real-time location systems (RTLS) based on RSSI (Received Signal Strength Indication) measurements. An embodiment is based on determining the distances between wireless device of a network based on a model that describes the relation of the RSSI value relative to the packet exchanged between nodes as a function of the distance, wherein said model depends on at least one characteristic parameter of the transmission channel and wherein at least said characteristic parameter of the transmission channel is determined periodically and automatically, exploiting the known distances among fixed nodes. In this way, the errors relative to possible time-variability of the transmission channel are reduced and the accuracy and stability of the location measurements are increased.
