| Abstract(in English) | In this paper, we propose and develop a novel location awareness system using Bluetooth function of the cell phone. Recently, various services for the portable terminal are expected owing to improvement of the transmission rate of the portable terminal. For the last several years, the number of cell phone with Global Positioning System (GPS) function has increased and we can determine the position by its GPS coordinate. It is difficult to determine the accurate location in the building because it is hard to monitor the GPS satellites at the cell phone. There are location awareness systems using Wireless Local Area Networks (WLAN) of laptop PC or PDA. Although these systems determine the position using the receiving signal strength of the radio waves from some access points of the WLAN, we need to set many access points. In this paper, we propose and develop the location awareness system using the Receiving Signal Strength Indicator (RSSI) of Bluetooth function of the cell phone in the building. In this system, we estimate the position based on the difference between RSSI's from several Bluetooth transmitters. We show availabilities of the proposed system by some experiments. |
