Description
Summary:This paper introduces the significance of indoor positioning and analyzes the related problems. The latest research on indoor positioning is introduced. Further, the positioning accuracy and the cost of typical local and wide area indoor positioning systems are compared. The results of the comparison show that Time ＆ Code Division-Orthogonal Frequency Division Multiplexing （TC-OFDM） is a system that can achieve real-time me- ter-accuracy of indoor positioning in a wide area. Finally, in this paper, we indicate that the seamless high-accuracy indoor positioning in a wide area is the development trend of indoor positioning. The seamless Location Based Services （LBS） architecture based on a het- erogeneous network, key technologies in indoor positioning for decimeter-accuracy and seamless outdoor and indoor Geographic Information System （GIS） are elaborated as the most important research fields of future indoor positioning.
