In the last decade, the interest in Indoor Location Based Services (ILBS) has increased stimulating the development of Indoor Positioning Systems (IPS). In particular, ILBS look for positioning systems that can be applied anywhere in the world for millions of users, that is, there is a need for developing IPS for mass market applications. Those systems must provide accurate position estimations with minimum infrastructure cost and easy scalability to different environments. This survey overviews the current state of the art of IPSs and classifies them in terms of the infrastructure and methodology employed. Finally, each group is reviewed analysing its advantages and disadvantages and its applicability to mass market applications.
在过去十年中，对室内定位服务（ILBS）的兴趣不断增加，这刺激了室内定位系统（IPS）的发展。特别是，ILBS寻求能够在全球任何地方应用于数百万用户的定位系统，也就是说，需要开发用于大众市场应用的IPS。这些系统必须以最低的基础设施成本提供准确的位置估计，并易于扩展到不同环境。本综述概述了IPS的当前技术水平，并根据所采用的基础设施和方法对其进行分类。最后，对每个类别进行了评估，分析了其优缺点及其在大众市场应用中的适用性。
