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."
