High Frequency wireless (millimeter wave) can deliver speeds well into the gigabits. At millimeter wavelengths you can aggregate hundreds oMillimeter wave textboolf MHz of spectrum compared to the 20 MHz typical of today's wireless networks. High frequency antennas are very small, so it's practical to put 50 of them on a chip for massive MIMO.

Rappaport, Heath and colleagues are world leaders in research in millimeter wave high frequencies and MIMO. Rappaport's NYU Wireless Center has been sending teams out to get empirical data on frequencies like 28 GHz. They are testing in two of the toughest locations for a wireless network: Manhattan and Downtown Brooklyn. Heath at the University of Texas built one of the first MU MIMO testbeds.

With literally $billions going into 5G wireless research you need the latest information and best sources.

Many of the claims in traditional wireless textbooks are not proving out in empirical testing. This book is current & well-informed and likely to be the standard for years if the authors' issue regular updates. It's a technical book and not easy reading for non-engineers but the style is clear and the explanations well written.

For the record, I'm a technology writer who has interviewed two of the authors on several occasions. Rappaport was part of a webinar I did for the Marconi Society.

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.

 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.
