Abstract
A method and apparatus is provided for determining a mobile station's position by utilizing modified Wi-Fi signals and transmitting and receiving Wi-Fi signals by a plurality of base stations, receiving signals transmitted by these base stations (which have known coordinates) and located in some proximity to the mobile station, and calculating position coordinates of the mobile station (also referred to herein as a mobile object) based on the signals.
Claims20
A method for determining a position of a mobile station comprising:
- exchanging a plurality of Wi-Fi signals among the mobile station and a plurality of base stations, the Wi-Fi signals comprising a plurality of orthogonal frequency division multiplexed (OFDM) communication signals;
- and
- determining the position of the mobile station based on the OFDM communication signals.
A system comprising:
- a mobile station;
- and
- a plurality of base stations,
- wherein the system is configured to perform operations comprising:
- exchanging a plurality of Wi-Fi signals among the mobile station and the plurality of base stations, the Wi-Fi signals comprising a plurality of orthogonal frequency division multiplexed (OFDM) communication signals;
- and
- determining a position of the mobile station based on the OFDM communication signals.
A mobile station comprising:
- a processor;
- and
- a memory, storing computer program instructions, which when executed by the processor, cause the processor to perform operations comprising:
- receiving a plurality of Wi-Fi signals from a plurality of base stations, the Wi-Fi signals comprising a plurality of orthogonal frequency division multiplexed (OFDM) communication signals;
- and
- determining a position of the mobile station based on the OFDM communication signals.
