AB  - Location Based Services (LBS) are an important permissive technology and it have wide range of
application. The main component of LBS is location detection. It can be divided into proximity, triangulation
and fingerprint. Fingerprint Wi-Fi has been preferred technology due to its accurate positioning results and
minimal infrastructure cost. It is conducted in offline and online phase. In the first phase, a site survey is
conducted to collect the vectors of Received Signal Strength Indicator (RSSI) at many reference points of
known locations. Then users measures RSSI vector at their position in the online phase. System compares the
received target vector with the stored fingerprints. People Presence Effect (PPE) has a dominant influence to
RSSI in a dynamic environment. It is necessary to further research related to PPE so that it can be generated
a more accurate indoor positioning system in dynamic environments such as airports, hospital and shopping
area.
