CAPTURE: A Mobile Based Indoor Positioning System using Wireless Indoor Positioning System
International Journal of Interactive Mobile Technologies (iJIM), 2018 The existence of mobile devices as a location pointing device using Global Positioning System (GPS) is a very common thing nowadays. The use of GPS as a tool to determine the location of course has a shortage when used indoors. Therefore, the used of indoor location-based services in a room that leverages the use of Access Point (AP) is very important.
