5G Brooklyn Summit

If you can't come to New York, watch the IEEE live stream. April 25-27

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. 

Paulraj, Fettweis, Dina Katabi, are among the world's top researchers.In 2014, AT&T's #2 John Stankey and the CTO of NTT DOCOMO Seizo Onoe convinced me 5G was going to be real.  Both are coming back. 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 askAugust 2018 Verizon's $20B 5G build is starting to add customers in 2018. Gigabit LTE & Massive MIMO became real in 2017 and enow expanding worldwide. Almost all the other "5G" is mid-band, 70%-90% slower + hype. Europe is mostly pr. The term 5G has been bastardized, unfortunately.

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.

Send questions and news to Dave Burstein, Editor. I always want to hear from you, especially if you catch a mistake.


 5G Why Verizon thinks differently and what to do about it is a new report I wrote for STL Partners and their clients.

STL Partners, a British consulting outfit I respect, commissioned me to ask why. That report is now out. If you're a client, download it here. If not, and corporate priced research is interesting to you, ask me to introduce you to one of the principals.

It was fascinating work because the answers aren't obvious. Lowell McAdam's company is spending $20B to cover 30M+ homes in the first stage. The progress in low & mid-band, both "4G" and "5G," has been remarkable. In most territories, millimeter wave will not be necessary to meet expected demand.

McAdam sees a little further. mmWave has 3-4X the capacity of low and mid-band. He sees an enormous marketing advantage: unlimited services, even less congestion, reputation as the best network. Verizon testing found mmWave rate/reach was twice what had been estimated. All prior cost estimates need revision.

My take: even if mmWave doesn't fit in your current budget, telcos should expand trials and training to be ready as things change. The new cost estimates may be low enough to change your mind.
