Korea building 230Ted Rappaport pointed me to Jerry Pi's paper from 2011, one of the very earliest contributions to 5G mmWave. Pi wrote An introduction to millimeter-wave mobile broadband systems when was at Samsung. He writes, "The first publication is a patent application in 2010. As you know, Samsung was the first to show a 28 GHz 5G demo to the world in 2013, while most other companies just started to look into this idea. In my view this certainly helped Samsung establish its technology and product leadership in 5G and grow its 5G business."

Samsung's leadership in wireless research is paying off big time, with Samsung now supplying Verizon. Samsung's showcase customer is Reliance Jio in India, now with 225 million 4G subscribers after only two years. Jio and China's 344M fiber home lines connected (not passed) are the two most spectacular achievements in my 20 years reporting broadband.

In 2012, Samsung became true believers in mmWave and put hundreds of engineers to work. (Ted visited and presented to them.) The complexity of chips and networks today is astonishing. An effort like Samsung, Qualcomm, or Ericsson involves thousands of engineers and billions of dollars. 

It wasn't until Ted's paper Millimeter Wave Mobile Communications for 5G Cellular: It Will Work! in 2013 that most of the industry took notice and went to work. Ted's just won an Armstrong Award.

Pi went on to be CTO of Straight Path, which was sold to Verizon for US$3 billion. He did very well and his Linkedin profile now lists him as "retired."

 

 

Mobile communication has been one of the most successful technology innovations in modern history. The combination of technology breakthroughs and attractive value proposition has made mobile communication an indispensable part of life for 5 billion people. Due to the increasing popularity of smart phones and other mobile data devices such as netbooks and ebook readers, mobile data traffic is experiencing unprecedented growth. Some predictions indicate that mobile data will grow at 108 percent compound annual growth rate (CAGR) [1] with over a thousandfold increase over the next 10 years. In order to meet this exponential growth, improvements in air interface capacity and allocation of new spectrum are of paramount importance.

Rethinking Jan 27: Coronavirus could invalidate all projections. I reported on AIDS for 2 years. This could be worse because it spreads in air. Let us hope and pray.

Welcome  Asia is installing hundreds of thousands of 5G radios and adding 5G subs by the tens of millions. The west is far behind. 200,000,000 in 2020

The demand is there, and most of the technology works. Meanwhile, the hype is unreal. Time for reporting closer to the truth.
