为了验证我们以前报告的自主室内定位系统在实际环境中的有效性，我们实现了它在一个基于ZigBee标准的无线传感器网络。系统通过测量适当数量的传感器节点处的RSSI（接收信号强度指示符）来自动估计传感器节点之间的距离。通过实验，我们阐明了我们的数据收集和位置估计技术的有效性。结果表明，当传感器节点部署密度为0.27个/时，位置估计误差减小到1.5 ~ 2 m。
To verify the validity of our previously reported autonomous indoor localization system in an actual environment, we implemented it in a wireless sensor network based on the ZigBee standard. The system automatically estimates the distance between sensor nodes by measuring the RSSI (received signal strength indicator) at an appropriate number of sensor nodes. Through experiments, we clarified the validity of our data collection and position estimation techniques. The results show that when the deployment density of sensor nodes was set to 0.27 nodes/ , the position estimation error was reduced to 1.5-2 m.
