Research & Development of WLAN-based Location Techniques
基于无线局域网的位置定位技术研究和发展

In recent years, with the rapid development of WLAN techniques and the wide deployment of WLAN networks in the world, the WLAN-based loeation technique has become a hot topic in the research of indoor location services. This technique is simple with respect to the equipment which uses current infrastructures of WLAN to realize indoor/outdoor location services. Compared with other existing indoor location techniques, it can reach higher location accuracy,cover larger indoor/outdoor area and is much easier to be integrated into other information services. This paper gives an introduction to WLAN-based location techniques, and also analyzes their features and development by investigating several typical WLAN based location systems.
