Abstract: At least some embodiments of the present invention are directed to RFID reader systems configured to estimate a directional bearing of an RFID tag. In an embodiment, the present invention is an RFID system configured in a way that upon a detection of a variance in the direction of a maximum RSSI value for a given RFID tag in response to a plurality of interrogation signals transmitted by an RFID reader over a respective plurality of different directions, the RFID reader retransmits the plurality of interrogation signals over the respective plurality of different directions with successively lower power levels until the only response(s) being received no longer exhibit the previously detected variance.

Abstract: Systems and methods for determining a position of at least one element are disclosed herein. The system receives, by a device having a first sensor, angle of arrival data from at least one element having a second sensor. The system receives position information of the device within a room and determines a difference in height between the device and the at least one element based on a first pressure measurement of the first sensor and a second pressure measurement of the second sensor. The system generates a vector between the device and the at least one element based on the angle of arrival data and determines a plane indicative of a height of the at least one element based on the determined difference in height. The system determines a position of the at least one element based on an intersection of the vector and the plane.
