5G Brooklyn Summit

If you can't come to New York, watch the IEEE live stream. 

Ted Rappaport's Brooklyn 5G may be the best event in the industry. Top people come to NYU Wireless, the leading academic 5G center. Speaking to an audience of peers, they bring the latest and most important research. 

In 2014, AT&T's #2 John Stankey and the CTO of NTT DOCOMO Seizo Onoe convinced me 5G was going to be real.  Folks at that level wouldn't have flown from around the world unless 5G was closer than I thought.

Listening at the shows, I realized that the massive number of cells for 5G mmWave was likely a competition killer. The general opinion was that only one or two companies could afford to build such large networks. (Encouraging note: The reach of mmWave is proving better than most people expected.)

In 2016, Onoe and others thought volume deployments were unlikely before 2022-2023. By 2017, Onoe had changed his mind and said 2020. At the 2017 event, I gathered datapoints that led me to write Verizon Full Speed Ahead on $20B mmWave Buildout.  8 months later, Verizon hasn't officially announced but I'm confident about the story.

At the first Brooklyn Summit I asked about competition problems for 5G networks based on high frequencies. They generally require fiber backhaul to an enormous number of small cells because of the limited range. The incumbent has an enormous advantage because of all the fiber they own. Stanford's Andrea Goldsmith, one of the best, answered by pointing to the alternative of Bottoms-up networks, supplied through existing DSL and cable backhaul. She was so on target I apologized to her for asking a simplistic question.

The 5G Summit is primarily a technical event but it's time for the policy people to begin listening. 



dave askDec 2017 Verizon just confirmed the $20B 5G build is on, as I reported in May. Gigabit LTE is real in 2017. So is 5G Massive MIMO. 5G mmWave to fixed antennas is likely 2018, with mobile to follow. China, Japan, Korea, and Verizon U.S. are firm, with heavy investment expected 2019-2021. 

Being a reporter is a great job for a geek. I'm not an engineer but I've learned from some of the best, including the primary inventors of DSL, cable modems, MIMO, Massive MIMO, and now 5G mmWave. Since 1999, I've done my best to get closer to the truth about broadband.
