Method and apparatus for indoor positioning based on wireless landmarks

A method to calibrate sensors of a mobile device for indoor positioning:

• receiving a wireless signal from a transmitter;
• decoding the received wireless signal to generate a decoded signal;
• determining, based on the decoded signal, that the received wireless signal has a predetermined power and a predetermined frequency;
• identifying a position of the mobile device, based on the determining;
• and
• calibrating, based on the position, a physical sensor of the mobile device within thresholds used for indoor positioning.

A device to perform wireless indoor positioning of a mobile device, comprising:

• an indoor positioning signal generator configured to:
• generate a signal to transmit to the mobile device, the signal to be received and decoded at the mobile device;
• wherein the signal has a predetermined transmission rate and a predetermined power that is known to be decodable by the mobile device only when the mobile device is within a predetermined distance from a transmitter;
• and
• wherein the signal includes data identifying a location of an access point (AP);
• and
• a wireless signal transmitter configured to transmit the signal to the mobile device.

A device to perform calibration of sensors of a mobile device for indoor positioning, comprising:

• a wireless signal receiver configured to receive a wireless signal from a transmitter;
• a decoder configured to decode the received wireless signal to generate a decoded signal;
• and
• a positioning processor configured to:
• determine, based on the decoded signal, that the received wireless signal has a predetermined power and a predetermined frequency;
• identify a position of the mobile device, based on the determining;
• and
• calibrate, based on the position, a physical sensor of the mobile device within thresholds used for indoor positioning.
