Indoor positioning systems (IPS) aim at obtaining an estimate of the localization of a target inside buildings. Their use and applications have increasing scopes, ranging from context data forwarding in museums, object tracking, marketing, manufacturing, being a key technology for several IoT applications, and Industry 4.0. Power line communication (PLC) systems are a field with an increasingly scientific and industrial interest. PLC provides broadband connection using the existing mains, easing the connection of different devices. Consequently, one proposes to research how and to which extent PLC systems could be used for indoor positioning and what is the attainable accuracy of using PLC-based IPS. The PLC standards use multi-carrier schemes by means of OFDM (orthogonal frequency division multiplexing), which has also been used by the IEEE 802.11 (Wi-Fi) and visible light communication (VLC) systems. Therefore, one proposes to investigate PLC physical layer and medium access frame structures and the correspondent transceivers that could be seamlessly employed for IPS. The expected result is proposing strategies, sensors, devices, algorithms, and methods to employ PLC originated signals emitted from the power outlet or the light socket for indoor positioning. This would add “localization services” capacity to PLC systems. It is believed that these could foster the Internet of Things (IoT) and Industry 4.0 scenarios and improve energy usage efficiency and monitoring.

Lisandro Lovisolo has a background in the area of signal processing and his main interests are in the areas of signal processing, communication, and positioning – the underlying technologies and applications. He has researched signal compression, detection, and recognition of phenomena employing adaptive decomposition of signals and sparse representations – using them for different applications as modeling, compression, source separation, and other signal processing tasks, in special of power system signals. Another of his interests lies in the positioning and localization of devices using signals. In addition, he has dedicated time to the research, implementation, and development of wireless communication systems using different technologies (mobile networks, cell phones, etc.) and audio and video systems (Digital TV and Streaming). He has been an associate professor at the Department of Electronics and Telecommunications Engineering (DETEL) at the State University of Rio de Janeiro (UERJ). At UERJ he taught undergraduate and graduate courses and founded PROSAICO (Laboratory for Signal Processing, Intelligent Applications, and Communications – www.prosaico.uerj.br) in 2007. He obtained his doctorate in Electrical Engineering at Universidade Federal do Rio de Janeiro (UFRJ) in 2006. He was awarded the Young Scientist of Our State (JCNE) award at FAPERJ between 2012 and 2014 and between 2015 and 2017 and is a CNPq researcher since 2015. He was the General Coordinator of SBrT2019 (Brazilian Symposium on Telecommunications – www.sbrt.org.br/sbrt2019). He has coordinated and participated in research projects funded by different development agencies and companies. He was elevated to the rank of Senior Member of IEEE in 2018.
