Professor Song Joon Hwa develops new Location Tracking Application Professor Song Joon Hwa developed a location tracking application that alerts the teacher when students on field trips stray too far from the group via a smartphone and a headset. Conventional Location Tracking Applications utilize GPS systems and as a consequence does not function indoors where the satellite signal is nonexistent. However Professor Song’s method is unique in the fact that it utilizes radio waves which allows signal transfer both indoors and outdoors. In addition different alerts are given off in difference locations and therefore the technology can be applied in finding the effectiveness of the field trip and the social behaviors of students.
