> World-class accuracy of 1.96 meters Good for WiFi/IMU-based indoor (phone-based) position tracking, I believe. For more accuracy, especially for robotics, etc., Pozyx [1] claims resolution of "a few centimeters" (indoor rooms/outdoor) by using some custom trilateration circuitry, and then there are attempts to use VR (esp. Vive) methods [2], which are even better (albeit more limited range).
