Abstract
Using ground truth events and sensors available on a first mobile device, an algorithm executed at the first mobile device determines the mobile device's position; the first mobile device also obtains wireless signal information; the wireless signal information is associated with the position determined via the sensor data and ground truth events; the associated data is stored and may be sent to or used by a second device; the second device may then, for example, detect then-current wireless signal information and may locate the second device by looking up the then-current wireless signal information in the associated data.
