In recent years, WiFi localization systems have become increasingly popular owing to the ubiquity of WiFi-enabled devices. However, traditional WiFi networks were not originally designed for localization purposes, and changes to the Access Point (AP) locations can result in a significant drop in localization performance. Moreover, these systems suffer from the inability to generalize models trained in one building to other buildings, owing to dependencies on building characteristics and their WiFi configurations. To address this challenge, we propose MetaLoc: the first global indoor positioning system that can function in any environment in a plug-and-play manner without requiring recalibration. Towards this end, we introduce a novel concept called the ”Meta Environment,” in which users are tracked in a virtual environment rather than the physical environment. This enables the localization model trained on one environment to function in another, regardless of changes occurring in the network environment, as they share the same meta environment. Our experiments demonstrate that MetaLoc outperforms existing state-of-the-art systems by at least 35%. This superior accuracy is due to its robustness to changes in the WiFi environment and its adaptability to different building configurations. |
