Abstract
A mobile device positioning system includes a receiver to receive data on a plurality of signals received by a mobile device, each of the signals being from a transmitter in an area, the positioning system including a processor configured to execute computer program code for determining, in dependence on the data, a relative distance of the mobile device with respect to each transmitter associated with the respective signals and for determining a position of the mobile device in between the transmitters of the received signals in dependence on the determined relative distance.
Claims19
A mobile device comprising:
- a receiver configured to receive signals, each of the signals being from a transmitter in an area, and each of the signals including location coordinates of the respective transmitter relative to a predetermined origin;
- a processor coupled to the receiver, the processor configured to:
- determine a zone in the shape of a polygon, the polygon defined by four or more vertices, each vertex being a location of a transmitter, and the determination based on the location coordinates of the respective transmitter;
- calculate a signal strength of the transmitter at each vertex;
- determine a relative distance of the mobile device from within the zone to each vertex, each relative distance based on the signal strength of the transmitter at each vertex;
- and
- determine a position, relative to the predetermined origin, of the mobile device in the polygon based on each relative distance.
A method of determining a position of a mobile device, comprising:
- receiving signals by the mobile device from four or more transmitters, each signal including location coordinates of a respective transmitter relative to a predetermined origin;
- calculating, by the mobile device, signal strength of each signal;
- determining, by the mobile device, a zone in the shape of a polygon, the zone having four or more vertices, each vertex being a location of a transmitter, and the determining based on the location coordinates;
- and
- determining, by the mobile device, the position of the mobile device within the zone based on the signal strength of each signal.
