Location Based Service Using 2.45GHz Active Tag

In this thesis, the future-oriented system using RFID technology was developed for figure out the number of people following by the guide promptly and effectively every time location changes. By having the tourists carry RFID tag, the group leader can check the number of the tourists by collecting the information on surrounding tags real-time through PDA with attached RFID reader. To make this feasible, the RFID based location check for the group members were made possible. To examine the safety of the proposed system, the directionality of antenna was tested. The result showed that the presence of the followers can be easily checked using the reader, processing the signals from the active tag, it could overcome the limitations of the location which the existing the prevention of lost children system in theme parks.
