基于无线局域网信号的城区室内外无缝定位技术
WLAN Based Ubiquitous Positioning for Urban Indoor and Outdoor Environment
摘要
Abstract
Ubiquitous positioning is important in mobile geolocation services.In this paper,the signal strength based WLAN positioning technology is discussed.Outdoor public WLAN in telephone booth and indoor WLAN signals are used for positioning.A simplified wireless signal path-loss model for urban indoor and outdoor environments is proposed.By Cell-ID ranking and triangulation approaches,the positioning accuracy of outdoor WLAN is up to 2.1-25 m,and positioning accuracy of 0.8-4.2 m is derived for indoor environment.This technology can be applied for ubiquitous positioning services in urban indoor and outdoor environment.关键词
