Abstract: A system and method for locating objects using radio frequency identifiers is provided. Each object to be located by the user has an object unit attached thereto with a RFID transponder. The user carries a proximity unit with a RFID transponder and warning devices. The method comprises: -a controller receives the instruction to locate a specific object; the controller obtains RFID readings, from the main intermediate units associated with location areas, with information about the object units detected; -determining the location area of the object to be located; -sending information to the user about the location area; -detecting the presence of the proximity unit carried by the user when it is within the location area; -repeatedly obtaining, using readings of the RFID signal strength, information about the distance between the proximity unit and the object unit, reporting it to the user using warning devices.

Abstract: System and method for locating objects using radio frequency identifiers. Each object to be located by the user (5) has an object unit (4) attached thereto with a RFID transponder (61). The user (5) carries a proximity unit (3) with a RFID transponder (51) and warning means (52, 54, 55). The method comprises: —a controller (1) receives the instruction to locate a specific object; —said controller (1) obtains RFID readings, from the main intermediate units (2) associated with location areas, with information about the object units (4) detected; —determining the location area of the object to be located; —sending information to the user (5) about said location area; —detecting the presence of the proximity unit (3) carried by the user (5) when it is within said location area; —repeatedly obtaining, using readings of the RFID signal strength, information about the distance between the proximity unit (3) and the object unit (4), reporting it to the user (5) using warning means (52, 54, 55).
