近十年来，室内定位一直是一个活跃的研究领域，但到目前为止，商用室内定位系统（IPSs）还很少。广泛使用IPSs的主要障碍是缺乏适当的低成本技术，使室内定位成为可能。虽然Wi-Fi基础设施无处不在，但面向消费者的支持Wi-Fi功能的移动电话却一直缺失。相反，虽然蓝牙技术出现在绝大多数消费者移动电话中，但蓝牙基础设施却一直缺失。蓝牙基础设施通常作为完整的硬件/软件ips的一部分安装，这通常会产生大量的硬件成本。此外，与Wi-Fi设备相比，蓝牙功耗低，可以延长手机电池的使用寿命。在本文中，我们提出了一个完全基于商品级产品的蓝牙IPS。利用Wi-Fi定位文献中众所周知的位置指纹技术来评估定位精度。结果表明，2米的中值精度是可以实现的，这一结果与基于Wi-Fi的系统的结果相比是有利的。
Indoor Positioning has been an active research area in the last decade, but so far, commercial Indoor Positioning Systems (IPSs) have been sparse. The main obstacle towards widely available IPSs has been the lack of appropriate, low cost technologies, that enable indoor positioning. While Wi-Fi infrastructures are ubiquitous, consumer-oriented Wi- Fi enabled mobile phones have been missing. Conversely, while Bluetooth technology is present in the vastmajority of consumermobile phones,Bluetooth infrastructures have been missing. Bluetooth infrastructures have typically been installed as part of complete hardware-/software IPSs that often incur a substantial hardware cost. Furthermore, Bluetooth has low power consumption compared to Wi-Fi devices, which promotes longer battery life-time on mobile phones. In this paper, we present a Bluetooth IPS based entirely on commodity-grade products. The positioning accuracy is evaluated by using the so-called location fingerprinting technique which is well-known from Wi-Fi positioning literature. The results show that 2 meters median accuracy is achievable - a result that compares favourably to results for Wi-Fi based systems.
