US 2025/0028916 A1 · OBJECT POSITIONING AND TRACKING BASED ON RFID AND MILLIMETER WAVE SCANNING

Abstract

A method and system are directed to identifying, locating, and track locations of assets and actors within a local environment. The system comprises a millimeter wave (mmWave) antenna circuit coupled to a beam steering antenna (BSA). The mmWave antenna circuit comprises an mmWave processing unit (MPU) coupled to an RFID integrated circuit. An RFID reader may be configured to scan and locate RFID tags attached to assets within particular zones/beams of the local environment by communicating with the RFID integrated circuit. The MPU is configured to scan for actors in the particular zones/beams, generate a point cloud to determine actor positions within the point cloud, and communicate point cloud position data to the RFID integrated circuit.

Dependent claims

An antenna unit comprising:

a coupler coupled to a reader computing entity at an input port of the coupler;
a radio frequency (RF) switch coupled to a first output port of the coupler;
a radio frequency identification (RFID) integrated circuit (IC) coupled to a second output port of the coupler, the RFID IC configured to select between a local beam steering antenna and a switch antenna for RFID scanning by switching RF switch based on read instruction signals from the reader computing entity;
a mmWave processing unit (MPU) coupled to the RFID IC, the MPU configured to:
(i) generate point cloud position data and (ii) transmit the point cloud position data to the RFID IC;
and
a mmWave antenna element coupled to the MPU.
