Abstract
A positioning determination method using an improved RFID location tag is described the tag including an RFID controller; memory; a power management module; and an accelerometer. The position determination method including the steps of periodically polling the RFID tags for information; receiving information from a plurality of reference RFID tags at a known location; receiving information from the non reference RFID tags, the information including the tag id and sensor data; calculating for each non reference and referenced RFID tag a received signal strength indication; and calculating an initial position for each non reference RFID tag based on the received signal strength indications and the positions of the reference RFID tags.
