Abstract
As the popularization and proliferation of smart phone and location based services, the necessity and importance of the location based service based on the smart phone becomes significant. But existing technologies could not be applied in real situation due to the lack of accuracy, economy, and convenience, the method using the signal strength of WLAN is not accurate. In this paper, the technical back ground, implementation issue, and measurement result are described for the proposed relative positioning technology using acoustic signal and Bluetooth with smart phone. It is possible to measure the position of the smart phone with accuracy and simple device, and it is very proper especially for the indoor location based intelligent services.
