Almost everybody thinks 5G mmWave will be very expensive, require vast numbers of small cells, and may not pay off.  That's all nonsense, according to Verizon CEO Hans Vestberg. He's done more testing of mmWave than anyone else except maybe Ted Rappaport and is probably correct. Here's what he said on CNBC:

5G is the same cost as 4G was. 

We designed 5G to make everything cordless.

Verizon is the first in the world. It's going to take some time to cover everyone but not a decade.

Spectrum is just one piece of the work. 

Stephane Richard at Orange/FT says the same, "I just want to remind everyone that our view is that 5G will not mean significant additional CapEx for us in the coming years. This is what we have constantly said and explained to the market, and this is still our view."

Samsung has delivered 5G chip samples to BBK's Oppo and Vivo, the #2 or #3 phones manufacturer. Samsung is facing off against Qualcomm in the 5G market. Qualcomm is unfazed and reportedly moving the production of their next chip from TSMC to Samsung. 

Sprint's 2.5 GHz 5G is delivering 100-500 megabit downloads consistently. That bodes well for China Mobile, using the same frequencies.

Vodafone, BT, and soon 3UK are delivering modestly sized 5G mid-band networks. Vodafone is also live in Spain and Italy. 

Sunrise in Switzerland is using 5G mid-band for fixed wireless in rural areas.

Welcome  1,000,000 Koreans bought 5G in the first ten weeks. 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.
