This technology relates to a location tracking system and method. Specifically, it is an AP signal and pedestrian-based location tracking technology that switches between indoor and outdoor modes.
Existing technologies were specialized for either indoor or outdoor environments, which meant conventional location tracking methods had limitations in that they could not track locations without distinguishing between indoor and outdoor. To overcome this, the present technology proposes a configuration that includes a location tracking system. This system comprises a server that receives signals from a user's nearby APs and measures AP signal strength, and a mobile terminal that transmits information about the measured signal strength and receives AP signal strength information.
Accordingly, this technology can improve the accuracy of location tracking by seamlessly transitioning between indoor and outdoor location tracking modes based on the user's location. It has practical value in the fields of IT, internet, smartphones, and software.
