System to locate at least one RFID tag in space, especially in an indoor environment, and its method.

摘要

The present invention relates to a system for locating at least one RFID tag in space, in particular in an indoor environment. In particular, said system and said method are conceived for locating the position of said object/subject, to which a RFID tag is applied, by the acquisition, on an azimuth plane and on an elevation plane, perpendicular to said azimuth plane, of power values of a signal received from one or more RFID tags present in a spatial region "read" by said reader, where said power values depend on the position of each RFID tag with respect to said reader, and by the acquisition of the distance between said reader and each RFID tag. The present invention relates to also a method for locating at least one RFID in space.
