          Using Wireless Signals by Opportunity for Cyber-physical Applications


          Speaker: Bo Tan (Assistant Professor), Tampere University, Finland 

          Time and Date: 10:00-11:00 am, May 10, 2019

          Place: Room 423 of Scientific Building, Handan Campus,Fudan University


          The pervasive deployment of the wireless sensor networks (WSN) in smart homes and cities has significantly changed the nature of the radio frequency spectrum, especially within the ISM band. The unplanned manner in which WSN nodes and anchors are deployed have led to a pell-mell of wireless bursts which limit the capacity and robustness of WSN's, while also increasing inter-system interference. The talk provides an alternative angle to disentangle the chaotic radio transmissions in congested wireless signal environments to offer a cyber-physical, especially human-related, sensing capability. The work focuses on extracting and interpreting the radio frequency properties of the wireless bursts in WSN, rather than the coded and modulated information. Examples of human activity sensing with 2.4 GHz 802.11 signals are shown to demonstrate the concept. The talk will also discuss the cognitive model, data fusion, identification problems derived from the opportunistic wireless sensing.



          Bo Tan is an Assistant Professor in Intelligent Machine, Faculty of Information Technology and Communication Sciences, Tampere University, Finland, also a visiting scholar in Department of Electronics and Electrical Engineering, University College London (UCL). He was an Assistant Professor in the Institute of Future Transportation and Cities, Coventry University, UK. He received his PhD in Digital Communications from the University of Edinburgh in 2013 and joined UCL and the University of Bristol as a postdoc researcher.  

          He participated in UK EPSRC flagship SPHERE IRC, EU ERC CHOASNETS projects, currently is Co-I of EPSRC OPERA project and Innovate UK PARI-IT project. He also worked for diverse firms like startups (electronics product design), Telecom operator (mobile service design), u-blox (early stage technology investigation) etc. His research on passive wireless sensing has been patented and cited by Qualcomm and Intel. His research outcomes have been promoted in autonomous system, security, healthcare, human-computer interactions (HCI), indoor positioning and smart home.
