Abstract:
1. A method of locating a user-device having a Wi-Fi radio, comprising: in response to a user application request to determine a location of a user-device having a Wi-Fi radio, triggering the Wi-Fi radio to transmit a request to Wi-Fi access points within range of the Wi-Fi device; receiving messages from the Wi-Fi access points within range of the Wi-Fi device, each message identifying the Wi-Fi access point sending the message; calculating signal strength of the messages received from the Wi-Fi access points; accessing a reference database of stored locations for Wi-Fi access points in a target area to obtain the stored locations for the identified Wi-Fi access points; based on the number of the identified Wi-Fi access points identified via received messages, choosing a corresponding location-determination algorithm from a plurality of location-determination algorithms; using the stored locations for the identified Wi-Fi access points, the signal strengths of the received messages and the chosen location-determination algorithm to determine the location of the user-device.
