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.

CFO John Stephens says AT&T is going to cut capex soon.

Bharti in India has lost 45M customers who did not want to pay the minimum USS2/month. It's shutting down 3G to free some spectrum for 4G. It is cutting capex, dangerous when the 12 gigabytes/month of use continues to rise.

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.
