Abstract

See full text

A hybrid positioning system can be implemented to improve location estimation of a wireless network device when reference network devices can have different distance calibration constants. For each of a plurality of positions at which the wireless network device is placed and for each reference network device, a distance between the wireless network device and the reference network device is determined. A first positioning algorithm is executed to determine an intermediate location (corresponding to each position) of the wireless network device and a distance calibration constant for each reference network device based, in part, on a corresponding initial location of the wireless network device. A second positioning algorithm is executed to estimate a subset of the positions of the wireless network device based on the intermediate location (corresponding to the position) of the wireless network device and the distance calibration constant of each of reference network devices.
