With the wide spread of smart phones equipped with GPS, WiFi, and Bluetooth sensors, Location Based Service (LBS) has become one of critical services for smart phone vendors, service providers, and users to date. Real time localization using GPS, WiFi, Bluetooth signals is an essential pre-step for location based services. Zigbee, RFID, or UWB can be commonly used for localization as well if they are attached to or integrated with smart phones. Among them, due to cost and coverage, we have been extensively studying and developing techniques for WiFi-based Real Time Locating System (RTLS) for the last several years. As a result, we developed a WiFi based indoor localization system, KAILOS, utilizing collective intelligence. It supports developing various indoor location based applications by providing location APIs. We also developed a WiFi-based indoor navigation system. The system was released to the public integrated with myCoex. It is known as the first commercial WiFi-based indoor navigation system applied to such a large area in real fields.
