Title: INDOOR POSITIONING SYSTEM UTILIZING BEAMFORMING WITH ORIENTATION- AND POLARIZATION-INDEPENDENT ANTENNAS
Abstract:
Orientation-independent antennas and associated beamforming circuits, to provide polarization-independent determination of position. An Indoor Positioning System (IPS) may utilize beacon or tag devices equipped with orientation-independent antennas to determine the location of nearby objects. The system can exist in many different customizable configurations, sometimes utilizing orientation-independent antennas embedded in smartphones that serve as beacon or tag devices. The devices, systems and methods described herein may be used for an IPS in a residential setting, a commercial setting (like a department store), an event or workplace, or an industrial setting.
