Abstract

Abstract Indoor/Outdoor (IO) detection (IOD) using Wi-Fi- and smartphone-based technologies is in high demand and interest in both the industrial and research fields. This paper proposes a novel and effective hybrid IOD (HIOD) approach for detecting a smartphone user's IO location. The HIOD approach uses signals received from both Wi-Fi and GPS as well as the latest positioning technologies such as multilateration, fingerprinting and machine learning. This paper proposes and implements two-level signal-to-noise ratio (SNR) threshold parameters for the first time, which are specifically derived from GPS signals through 42 empirical tests at seven test sites with adequate environmental factors considered. Using the newly derived IOD threshold parameters and a set of IO detection rules, the HIOD approach is then tested at 20 test points (TPs) in a city canyon area, where most of the TPs are under semi-indoor or semi-outdoor conditions. The final test results show that a 100% IOD rate is achieved.

一种用于智能手机无缝定位的室内/室外混合检测方法

摘要使用基于Wi-Fi和智能手机的技术的室内/室外（IO）检测在工业和研究领域都有很高的需求和兴趣。本文提出了一种新颖有效的混合IOD（HIOD）方法来检测智能手机用户的IO位置。HIOD方法使用从Wi-Fi和GPS接收的信号，以及最新的定位技术，如多点定位、指纹识别和机器学习。本文首次提出并实现了两级信噪比阈值参数，该参数是通过在7个测试点进行的42次经验测试，在充分考虑环境因素的情况下，从GPS信号中具体推导出来的。使用新导出的IOD阈值参数和一组IO检测规则，然后在城市峡谷地区的20个测试点（TP）测试HIOD方法，其中大多数测试点处于半室内或半室外条件下。最终测试结果表明，IOD率达到100%。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
