基于RFID标签的定位原理和技术

Positioning Principles and Localization Techniques Based on RFID Tags

识别和定位是用于室内服务的关键信息,常见方法是估计RFID标签的位置。而在室内环境下,信号遭受严重的损耗,标签的性能也会受到一定的限制。针对这些问题,文中对现存的RFID定位技术和定位原理加以总结,在对RFID定位技术进行阐释和分类分析的基础上,讨论了在此领域的未来发展趋势。

Both identity and location are generally key information for indoor services.RFID is an automatic identification technology that enables tracking of people and objects.An obvious and interesting method is to localize RFID tags.However,in indoor environments,signals are harshly impaired and tags have very limited capabilities which pose many challenges for positioning them.This paper reviews the state-of-art of RFID positioning principles and localization technology,explains and classifies RFID localization techniques,and finally discusses the future trends.
