Abstract
Localizing a location of a mobile device may be performed by obtaining times of flights between the mobile device and an access point at a first and second location. A heading of the mobile device and a distance between the first and second location may be further obtained. The times of flight, heading, and distance may be used to localize the second location.
Claims15
A method, comprising:
- obtaining a first time of flight between a mobile device at a first location and an access point;
- obtaining a second time of flight between the mobile device at a second location and the access point;
- obtaining a heading of the mobile device;
- obtaining a distance between the first location and the second location;
- using the first time of flight, the second time of flight, the heading, and the distance to localize the second location.
2 more elements
A system, comprising:
- a distance calculator to:
- use a first time of flight to determine a first distance between an access point and a mobile device at a first location;
- use a second time of flight to determine a second distance between the access point and the mobile device at a second location;
- and
- obtain a third distance between the first location and the second location;
- and
- a localizer to use the first, second, and third distances to localize the second location.
4 more elements
A non-transitory computer readable medium storing instructions executable by a processor to:
- obtain a heading of a mobile device;
- obtain a first distance from the mobile device to an access point when the mobile device is at a first location;
- obtain a second distance from the mobile device to the access point when the mobile device is at the second location;
- track a step frequency of a user of the mobile device as the user travels from the first location to the second location;
- use a relationship between step frequency and step length to determine a third distance between the first location and the second location;
- and
- use the first distance, the second distance, the third distance, and the heading to localize the second location.
