Title: Digital Twining for RF Cloud Interference Forecasting and Intelligent Spectrum Management
The RF signal radiated from billions of wireless communications and positioning devices create an RF cloud causing co- and cross-channel interference to each other. Lack of a science and technology for empirical understanding and modeling of stochastic behavior of the RF cloud interference in near real-time results in inefficient utilization of the precious spectrum, a unique natural resource shared among all wireless devices of the universe in frequency, time, and space. Near real time forecasting of the RF cloud interference is essential to pursue the path to the optimal utilization of spectrum and intelligent spectrum management (Pahlavan 22). A digital twin is a digital replica of a real-world physical entity (El Saddik 2018). In this lecture we first present a vision for creation of a digital twin of the location of popular RF communication (cellular, Wi-Fi, Bluetooth) and positioning (GPS, radars) devices. Then, we discuss implementation of a near real-time RF Cloud forecasting system benefiting from digital twining of location of RF devices.

Bio: Kaveh Pahlavan, is a Professor of ECE, a Professor of CS, and Director of the Center for Wireless Information Network Studies, Worcester Polytechnic Institute, Worcester, MA. From 2004-2014 he was the chief technical advisor of the Skyhook Wireless, Boston, MA, the world’s pioneer in Wi-Fi positioning for smart devices. From 1995-2007 he had cooperation with the University of Oulu and Nokia in Finland. He has received an “overseas famous scholar award” from R.I. China to serve as a visiting professor at University of Science and Technology of Beijing (2019-2022). He is renowned for his pioneering research in Wi-Fi, indoor geolocation, positioning for body area networks, and human-computer integration with RF cloud. He has contributed to numerous seminal visionary keynotes, papers, and key patents related to these areas. His current area of research is empirical theoretical foundations for RF cloud interference for intelligent spectrum management. He is the lead authors of several pioneering reference and textbooks translated and taught around the world in several languages. He is the founding Editor-in-Chief of the International Journal Wireless Information Networks, Springer Nature, established in 1994 as the first journal in wireless networks. He has founded, chaired, and organized several popular international events in wireless technologies and applications. For his pioneering entrepreneurship activities in the growth of wireless networking industry, he has been selected as a member of the Committee on Evolution of Untethered Communication, US National Research Council (1997), and has leaded the US team for the review of the Finnish National R&D Programs in (2000 and 2003). For his contributions in research and scholarship he was the Westin Hadden Professor of Electrical and Computer Engineering at WPI (1993-1996), was elected as a fellow of the IEEE (1996), became the first non-Finn fellow of the Nokia (1999), received the first Fulbright-Nokia fellowship (2000), and received WPI board of trustee’s award for Outstanding Research and Creative Scholarship (2011).
