摘要
随着智慧城市概念的提出,宽带无线通信技术WiFi等覆盖范围越来越广泛,智能手机的用户普及率越来越高,各行各业对定位业务的需求也越来越普遍。但是,对于室内定位因无线屏蔽效应很难借助GPS、北斗等卫星定位系统来实现。利用无处不在的WiFi信号和智能手机,设计了1套改进的基于位置指纹定位算法的室内定位系统。实验表明,该系统具有实现简单、使用灵活并具有较高的定位精度。
With the concept of smart city was raised,broadband wireless communication technology WiFi＇s coverage is more extensive and smart phone users are increased rapidly.It is also common for all walks of life to need location service.But,indoor positioning is difficult to implement by GPS and Beidou satellite as wireless shield.This paper use ubiquitous WiFi signal and smart phone,designed a indoor positioning system which based on location fingerprint algorithm.According to experiments,this system has the merit of implement simple,using flexibly and higher accuracy.
