In 2013, NYU's Ted Rappaport wrote Millimeter Wave Mobile Communications for 5G Cellular: It Will Work! based on thousands of tests his team did in the skyscrapers of New York. (Abstract below) 

      Ted's results were much better than almost anyone else expected and inspired the Nokia and Ericsson to confirm with their own testing. On October 1st, 2018, Verizon is turning on a true gigabit 5G network. Yes, I realize my headline is an exaggeration. Someone else would have discovered the properties of mmWave, probably years later. We wouldn't have it today.

      He just won the Armstrong Medal from the Radio Club of America. He's particularly honored to win this because, "when I was a dirt poor college student, and newly married, this organization gave me a scholarship that helped me decide to stay for grad school instead of taking a job." 

      The world would be a poorer place if he had left Academia. The Awards banquet November 17 in New York will be, "An amazing night in general. It will have very deep personal meaning for me, as I share publicly my walk with wireless and the many amazing mentors who shaped my life, and things  you may not have known about my life and career." Ted has shared some of the details. I guarantee it will be inspiring. 

      The world's best engineers come to the Brooklyn 5G Summit at NYU in the spring out of respect for the work done there. At the event, I've learned from Paulraj, Goldsmith, Onoe, and the leaders of just about every major company in the Western world. The two days are the best single place to learn about 5G and now 6G. If you want to learn what's coming next in wireless, watch the IEEE recording.

       Samsung funded the 2013 work, part of the six years of investment that now have made them an international player in wireless.

Some appreciations from his peers:

Ted's pioneering mm-wave research has profoundly influenced our research also on the other side of the Atlantic - such a richly deserved recognition of his vision! Prof. Lajos Hanzo FREng, FIEEE, FIEE, Fellow of EURASIP, DSc Univ. of Southampton

ABSTRACT The global bandwidth shortage facing wireless carriers has motivated the exploration of the underutilized millimeter wave (mm-wave) frequency spectrum for future broadband cellular communication networks. There is, however, little knowledge about cellular mm-wave propagation in densely populated indoor and outdoor environments. Obtaining this information is vital for the design and operation of future fifth generation cellular networks that use the mm-wave spectrum. In this paper, we present the motivation for new mm-wave cellular systems, methodology, and hardware for measurements and offer a variety of measurement results that show 28 and 38 GHz frequencies can be used when employing steerable directional antennas at base stations and mobile devices.

Radio Club of America Awards Armstrong Medal to Wireless Communications Researcher and Educator Theodore Rappaport

Armstrong Medal Honors Founder of NYU WIRELESS Research Center for His Lasting Contributions
September 28, 2018

BROOKLYN, New York, Friday, September 27, 2018 – The Radio Club of America (RCA) announced that Professor Theodore “Ted” Rappaport, founding director of NYU WIRELESS and a professor of electrical and computer engineering at the NYU Tandon School of Engineering, will receive the Armstrong Medal for demonstrated excellence and lasting contributions to radio arts and sciences.

Ted RappaportRappaport conducted seminal research, most recently in the millimeter wave (mmWave) radio spectrum. He advanced commercialization of this 5G technology that will bring broadband speeds to wireless communication – thereby potentially revolutionizing medicine, enabling autonomous vehicles, inexpensively connecting rural communities to the digital world, and more.

The RCA, the oldest worldwide organization of wireless communications professionals, also cited Rappaport for his lifelong contributions as an educator. In addition to his position as the David Lee/Ernst Weber Professor of Electrical Engineering at NYU Tandon, he is also on the faculty of the NYU Courant Institute of Mathematical Sciences and the Radiology Department of the School of Medicine.

Rappaport joins a distinguished group of past recipients of the Armstrong Medal — all luminaries in the wireless industry — including Arthur CollinsWalter CronkiteHarold BeverageMorgan O’Brien, and Major Edward H. Armstrong himself, who laid the foundations for much of the modern radio, including circuitry and the FM radio system.

In 1991, Rappaport was named an RCA Fellow at the age of 30, making him one of the youngest in recent history.

In 2012, Rappaport launched NYU WIRELESS at NYU Tandon, the first U.S. academic center to merge wireless engineering research with computer science and medicine. Since its founding, NYU WIRELESS has remained at the frontier of next-generation mobile technology, with undergraduate, graduate, and faculty researchers transforming the wireless field through their research into mmWave technology, channel modeling, Massive MIMO, beyond-5G technologies, circuits, and nano devices. The center pioneered mmWave frequencies for mobile communications and acted as an accelerant for the technology by bringing together leading businesses, institutes, and academic researchers at the annual Brooklyn 5G Summit.

Before Rappaport’s seminal paper “Millimeter Wave Mobile Communications for 5G Cellular: It Will Work!” many researchers disregarded the potential of the mmWave spectrum. It was Rappaport’s research that demonstrated to the world the viability of mmWave radio frequency bands, central to implementing 5G wireless technology.

In addition to the Armstrong Medal, Rappaport has received many prestigious honors throughout his career, including the Marconi Young Scientist Award (1990) and the Institution of Engineering and Technology Sir Monty Finniston Medal (2011). In addition to authoring and co-authoring more than 200 papers and 20 books in wireless communications, Rappaport holds more than 100 U.S. and international patents, founded two of the world’s largest academic wireless research centers prior to NYU WIRELESS, and founded and advised multiple wireless companies.

“Ted Rappaport has shown the world the future of wireless communications, not only through his work on mmWave technology but as a leader, researcher, and educator in the wireless field,” said Jelena Kovačević, dean of the NYU Tandon School of Engineering. “The RCA’s recognition of Ted, particularly with the Armstrong Medal, demonstrates how instrumental his work is on a global scale. His immense contributions have placed NYU Tandon on the map as a leader in wireless technology.”

Huawei in 16 days sold 1,000,000 5G Mate 20s.  

China has over 50,000 upgraded base stations and may have more than 200,000 by yearend 2019. The growth is astonishing and about to accelerate. China will have more 5G than North America and Europe combined for several years.

5G phone prices are down to $580 in China from Oppo. Headed under $300 in 2020 and driving demand.

No one believed me when I wrote in May, 90% of Huawei U.S. purchases can be rapidly replaced and that Huawei would survive and thrive. Financial results are in, with 23% growth and increased phone sales. It is spending $17B on research in 2019, up > 10%.

Welcome  1,800,000 Koreans bought 5G in the first four months. The demand is there, and most of the technology works. Meanwhile, the hype is unreal. Time for reporting closer to the truth.

The estimates you hear about 5G costs are wildly exaggerated. Verizon is building the most advanced wireless network while reducing capex. Deutsche Telekom and Orange/France Telecom also confirm they won't raise capex.

Massive MIMO in either 4G or "5G" can increase capacity 3X to 7X, including putting 2.3 GHz to 4.2 GHz to use. Carrier Aggregation, 256 QAM, and other tools double and triple that. Verizon sees cost/bit dropping 40% per year.

Cisco & others see traffic growth slowing to 30%/year or less.  I infer overcapacity almost everywhere.  

Believe it or not, 80+% of 5G (mid-band) for several years will be slower than good 4G, which is more developed.
