| Summary: | Research on positioning systems and context-aware applications are being performed in the Alipes project at CDT, Luleå University of Technology, Sweden. An evaluation of Bluetooth as a possible technology for positioning was performed during autumn of 2001 in this project. Proceeding the evaluation a Bluetooth based positioning system was implemented in order to complement the theoretical evaluation with empirical tests. Three different ways of positioning with Bluetooth have been developed for the Alipes project. With a registered positioning service a Bluetooth device has an active role in the positioning task as it sends a position on request. A Bluetooth device can also take a more passive role in a positioning task, which is when the unique address of the device is used by a connected device to look up a position in a database. It is also possible to forward a position gained from a positioning platform like Alipes over Bluetooth. This paper presents a Bluetooth positioning system where the three ways of positioning are implemented. The evaluation and conclusions of Bluetooth as a positioning source and how well Bluetooth performs in such a task are being discussed. To give support to the statements the implementation and tests are also presented. Godkänd; 2002; 20060918 (ysko)
