我们提供了一个简单的系统来帮助人们在建筑物内或甚至在建筑物附近的外部区域导航。它基于已建立的蓝牙链路的“RSSI”和“传输功率”数据。该系统原则上足以满足预期应用(行人、室内)，但它肯定不是一个高分辨率的室内定位系统。可实现的精度取决于设置(接入点及其星座和可用的蓝牙设备的数量)，但不会比几米量级的精度更好。该类指纹系统的主要特征是以概率密度函数的形式表示估计位置
We present a simple system to help people navigate inside of buildings or even in outside areas close to buildings. It is based on the "RSSI" and "transmit power" data of an established Bluetooth link. The system is in principle sufficient for the intended application (pedestrian, indoor), but it is certainly not a high resolution indoor location system. The achievable accuracy is dependent on the setup (number of access points and their constellation and available Bluetooth devices) but will not be better than in the order of several meters. A main feature of this fingerprinting-like system is the representation of the estimated position in the form of probability density functions
