Abstract
In indoor environments, global positioning systems can report inaccurate coordinates due to multipath, fading, lack of satellite visibility, etc., leading to a suboptimal user experience. This disclosure describes techniques that use positions of nearby mobile devices detected via short-range wireless communication to correct the location coordinates of a device. In such cases, each device obtains respective location coordinates via GPS, and the location coordinates are very similar. The short-range connectivity of such devices, referred to as tagged devices, serves as a strong prior that the engaged devices are proximal. The proximity is leveraged to reduce the error in their location estimates.
