无线局域网定位技术研究

The Research of WLAN-based Localization Techniques

介绍了基于无线局域网的室内定位系统,并结合三种不同的定位系统,分析了各种不同的定位技术,以及它们在提高系统定位精度方面的作用。结果表明,概率模型等技术能显著提高系统的定位精度。最后对无线局域网定位技术今后的研究方向进行了展望。

This paper gives an introduction to Indoor localization Systems based on Wireless LAN. Different techniques, used by three different localization systems, are described and compared with respect to their contribution to the accuracy of the resulting position. The results show that probabilistic approach and other techniques promote the accuracy of localization systems evidently. Finally, the paper indicates future research directions of WLAN-based localization technique.
