This 2-day online course, previously recorded by IEEE Com Soc, covers the fundamental communications, circuits, antennas and propagation issues surrounding emerging 60 GHz wireless LAN and mmWave cellular/backhaul applications. The course was developed and delivered by Professor Theodore (Ted) Rappaport, a pioneering researcher and educator in mmWave wireless communications, wireless systems and radio propagation and founder of NYU WIRELESS. It closely follows his textbook, "Millimeter Wave Wireless Communications," by T. Rappaport, R.W. Heath, R. Daniels and J. Murdock which is bundled with this course as an eBook download. In addition, class notes are provided as a pdf download with more than 300 pages of information. The course can be played at your own pace and stopped/repeated at any point since it is in video format with one file for each day.
It's true that average download speeds have increased in obedience with Cooper's law from a few megabits per second in 2010 to about 50 Mbps in 2020. However, peak throughput data rates over the same time frame have scaled by more than a factor of 1000, from megabits per second to gigabits per second. In fact, the wireless industry trade association CTIA has shown that the total capacity carried over the US cellular network increased a staggering 96 times from 2010 to 2019, with the average smartphone user consuming 9.2 gigabytes of data per month in 2019.
The Federal Communications Commission (FCC) saw the clear need for legislation that would enable wireless carriers to rapidly densify the network throughout the United States. The agency's 2018 Small Cells Order made small cells one of the three key technical pillars that will eventually support future terabit per second wireless communications.
The wireless industry groupthink has traditionally considered omnidirectional antennas to be the norm in wireless communications. But beginning with 5G, wireless systems are using directional antennas that have high antenna gains and narrow beamwidths on both the mobile and the base station ends of each link. This offers more, not less, signal strength to each user as we move to millimeter wave, sub-terahertz, and ultimately terahertz frequencies.
Theodore (Ted) S. Rappaport is the David Lee/Ernst Weber Professor of Electrical Engineering at the NYU Tandon School of Engineering (NYU-Tandon), and founding director of NYU WIRELESS, a multidisciplinary research center focused on the future of wireless communications and applications. He is a professor of computer science at New York University's Courant Institute of Mathematical Sciences and of radiology at the NYU School of Medicine. Earlier in his career, he founded the Wireless Networking and Communications Group (WNCG) at the University of Texas at Austin in 2002 and the mobile communications research center now called Wireless@ at Virginia Tech in 1990. 2b1af7f3a8
