AI Technical Summary
Technical Problem
Existing CSI-based Wi-Fi positioning systems require labor-intensive manual calibration for determining AP locations and antenna array directions, and are affected by down-sampling phase differences, hindering large-scale deployment.
Method used
A CSI-based location sensing method that automatically calibrates by obtaining angle differences of arrival (ADoA) using non-linearly arranged antennas, eliminating the need for manual calibration and phase offset correction.
Benefits of technology
Enables high-precision positioning without manual calibration of AP locations and antenna directions, reducing workload and enabling large-scale deployment.
