近年来,信息化、全球化已成为社会和经济发展的主旋律,人们在生活与工作中对信息的看法日益成熟,对信息的及时性、快捷性和安全性的要求也越来越严格。无线技术作为当前主要的信息传输方式,在全球信息化发展潮流的带动下必然会得到更高层次的发展,这位无线测距及定位技术的发展奠定了扎实的市场基础。本文主要介绍了几种基于现有无线蜂窝通信系统的定位技术原理,并针对其中存在的问题提出了有关应对策略。
In recent years, informationization and globalization have become the main theme of social and economic development. People’s perception of information in their daily life and work is becoming increasingly mature, and the requirements for the timeliness, speediness and security of information are becoming more and more stringent. As the current main information transmission mode, wireless technology is bound to get a higher level of development driven by the trend of global information development. This wireless market has laid a solid foundation for the development of wireless ranging and positioning technologies. This paper mainly introduces several positioning technology principles based on the existing wireless cellular communication system, and puts forward some countermeasures for the existing problems.
