A-Study-on-Indoor-Positioning-System-Using-ID-Mod

  In recent years, stepping with the popularization of smart phone and the development of mobile communication infrastructure, the conditions for ubiquitous computing society become more and more complete. In the vision of ubiquitous computing society, LBS (Location Based Service) that provides an added value to an unprecedented user experience has been paid a great deal of attention by mobile operators all over the world. As the core technology for LBS, various positioning systems have been studied extensively. For the outdoor environment GPS is mature and common.
