Dr. Harish Viswanathan

Title: Communications in the 6G Era


Dr. Harish Viswanathan is Head of Radio Systems Research Group in Nokia Bell Labs. He received the B. Tech. degree from the Department of Electrical Engineering, Indian Institute of Technology, Chennai, India and the M.S. and Ph.D. degrees from the School of Electrical Engineering, Cornell University, Ithaca, NY. Since joining Bell Labs in October 1997, he has worked extensively on wireless research ranging from physical layer to network architecture and protocols including multiple antenna technology for cellular wireless networks, multi-hop relays, network optimization, network architecture, and IoT communications. He has published extensively with over 100 publications. From 2007 to 2015, Harish was in the Corp CTO organization, where as a CTO Partner he advised the Corporate CTO on Technology Strategy through in-depth analysis of emerging technology and market needs. He is a Fellow of the IEEE and a Bell Labs Fellow.


The future of connectivity is in the creation of digital twin worlds that are a true representation of the physical and human worlds at every spatial and time instant, unifying our experience across these physical, human and digital worlds. New themes are likely to emerge that will shape 6G system requirements and technologies such as: (i) new man–machine interfaces created by a collection of multiple local devices acting in unison; (ii) ubiquitous universal computing distributed among multiple local devices and the cloud; (iii) multi-sensory data fusion to create multi-verse maps and new mixed-reality experiences; and (iv) precision sensing and actuation to control the physical world. We then discuss new connectivity technologies for 6G such as native AI/ML air-interface, joint communication and sensing, sub-Thz system design, and new architectures.
