Millimeter wave technology has seen an innovative journey in the past 100 years, starting with the ground breaking work by Indian scientist J.C. Bose who first performed pioneering research on radio waves between 1894 and 1900. Using creative techniques, Bose developed equipment for generating, transmitting, and receiving radio waves, often as short as 5 millimeters. Over the next 100 years, mmWave technology has progressed significantly, covering the spectrum from 30GHz to 300GHz. Today, it is the key enabling technology for applications such as the fifth generation of cellular technology (5G), automotive radar and connected cars, and wide bandwidth wireless connectivity. Understanding how the channel conditions impact these millimeter waves is the key in designing the right types of waveforms, signal processing techniques, and hardware for these applications. Various mmWave propagation channel models for various frequencies and environmental conditions are currently available from different research groups, but it lacks consistency and use case. The need for defining a common methodology and system to do such measurements efficiently and create/validate the channel models will be presented. Requirements for channel sounding systems, such as path loss, time of arrival, and maximum excess delay, will be discussed in detail. Finally, some initial mmWave channel sounding results for 5G and automotive radar applications will be presented.

Biography of Abhay Samant:
Dr. Samant was formerly Section Manager of RF Product Marketing at National Instruments. He is a senior member of IEEE and has over 20 years of experience in the areas of RF, wireless communications, and signal processing. Abhay has multiple patents in the areas of GPS, WLAN, and signal intelligence. He is co-author of the book, LabVIEW for Signal Processing and has published numerous conference and journal papers. In previous roles, Abhay has served as the Regional Marketing Manager for NI (India, Russia, Arabia), R&D Head for NI-India and has played multiple engineering and management leadership roles at NI R&D in Austin. Abhay received his PhD in Electrical Engineering from the Indian Institute of Technology in 2016, MS in Computer Science from the University of Illinois at Urbana-Champaign in 1996 and his MS in Electrical Engineering from the University of Kentucky at Lexington in 1994. Abhay’s research interests include hybrid, reconfigurable architectures for MAC-PHY technologies for wireless communications, design of mmWave systems for 5g, WGig, and automotive radar applications, and developing creative technologies for making learning fun. Abhay’s research areas also include application of communication signal processing techniques onto real-time high performance computing architectures and development of scalable and flexible test-bed architectures for spectrum monitoring, signal intelligence, connected car, and radar applications.
