Nuclear engineering This research is aimed to overcome the poor coverage of the Global Positioning System (GPS) in indoor environment. The indoor positioning system developed is based on the wireless local area network (WLAN) using the IEEE 802.11n standard.

An Arduino Wi-Fi Shield CC3000 is connected to an Arduino Mega is used to collect received signal strength (RSS) from individual wireless routers in predefined space to determine the location of the user/object. The data then will go through the predefined lookup table to locate the location of the user/object and the location will send to the MATLAB. The location of the user/object will then show in the graphic user interface in MATLAB. A set of experiment is conducted to identify the behavior of the RSS value toward the router. From the experiment, the potential factors that affect the performance of the positioning system is examined and identified.

The positioning system is developed with a fine performance and with a best accuracy of 100% at radius of less than 2m around the predefined point, accuracy of 70% - 60% at radius of 2 - 3 m radius, accuracy of 50% - 40% at 3 - 4 m radius and 30% - 20% at 4 - 5 m radius.
