Abstract: A method of determining a location of an RFID tag may be provided. The method may comprise obtaining first received signal strength data associated with a first tag volume and relating to signals received from the tag at a first plurality of locations relative to the tag, and second received signal strength data associated with a second tag volume different from the first tag volume and relating to signals received from the tag at a second plurality of locations relative to the tag. The method may comprise determining, depending on the first and second received signal strength data, point of peak data indicative of a location with respect to the first and second tag volumes of peak received signal strength from the tag. The method may comprise determining value(s) of one or more further received signal parameters depending on the first and second received signal strength data. The method may comprise determining which of the first and second tag volumes the RFID tag is more likely to be located in depending on the point of peak data and on the determined values of the one or more further received signal parameters.
