  • Method and apparatus to correct indoor positioning by utilizing Wi-Fi handovers
    Patent number: 9332476
    Abstract: A system and method may dynamically correct the dead reckoning (DR) position of a mobile device. An indoor or outdoor venue may have Access Points (APs) dispersed around its interior. Each time that a mobile device experiences a handover from one AP to a new AP, the mobile device and/or the local network associated with the venue may determine whether or not the mobile device's DR position corresponds to the location of the new AP. If the mobile device's DR position does not correspond to the location of the new AP within a predetermined threshold, then the mobile device's DR position may be updated to a position associated with the new AP. As a result, the DR position of the mobile device may be continuously checked, and if need be, corrected at each AP handover associated with the venue. The APs may be Wi-Fi/WLAN APs, eNodeB's, or other APs.
