Effective solutions are needed to provide contact-free, easy deployment, low-cost, and long-term vital sign monitoring. In this article, we present PhaseBeat to exploit channel state information, in particular, phase difference data to monitor breathing and heart rates with commodity WiFi devices. We provide a rigorous analysis of channel state information phase difference with respect to its stability and periodicity. Based on the analysis, we design and implement the PhaseBeat system with off-the-shelf WiFi devices and conduct an extensive experimental study to validate its performance. Our experimental results demonstrate the superior performance of PhaseBeat over existing approaches in various indoor environments.<\/jats:p>","DOI":"10.1145\/3377165","type":"journal-article","created":{"date-parts":[[2020,5,30]],"date-time":"2020-05-30T12:23:30Z","timestamp":1590841410000},"page":"1-27","update-policy":"https:\/\/doi.org\/10.1145\/crossmark-policy","source":"Crossref","is-referenced-by-count":99,"title":["On CSI-Based Vital Sign Monitoring Using Commodity WiFi"],"prefix":"10.1145","volume":"1","author":[{"given":"Xuyu","family":"Wang","sequence":"first","affiliation":[{"name":"California State University, Sacramento, CA"}]},{"given":"Chao","family":"Yang","sequence":"additional","affiliation":[{"name":"Auburn University, Auburn, AL"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7052-0007","authenticated-orcid":false,"given":"Shiwen","family":"Mao","sequence":"additional","affiliation":[{"name":"Auburn University, Auburn, AL"}]}],"member":"320","published-online":{"date-parts":[[2020,5,30]]},"reference":[{"key":"e_1_2_1_1_1","volume-title":"Proceedings of IEEE MobiHoc","author":"Abdelnasser H.","year":"2015","unstructured":"H.
