Magnetic-field (MF) IPS

  • Objectives: Create an IPS that is unaffected by moving humans, providing more time-invariant location information, unlike Wi-Fi, Bluetooth
  • Method: Use smart phone to create a radiomap of known MF patterns, then detect a new unknown RF pattern & derive the location
  • Results: Validate in a library, retail-like building, with multiple metal shelves & pillars, positioning error is 1.8 m. Scalability issues:  MF IPS pattern location accuracy drops as size of space increases
  • Conclusions: use of magnetic field (MF), unlike typical Wi-Fi or Bluetooth positioning measurements, are unaffected by moving humans, providing more time-invariant location information. We proposed a method to do detect the location quicker.
