Neville Ray, T-Mobile CTO, thinks Verizon 5G is heading for disaster if they build mmWave to the planned 30 million homes. He wishes them "Lots of Luck" in the illustrations at left and below, illustrated with skulls. Top Wall Street analyst Craig Moffett has looked in detail at Verizon's mmWave and infers it is currently limited to under 200 metres.
Ray's blog (excerpt below) begins "5G is at the height of the hype curve right now and there’s also a lot of misinformation." On the blog, Neville has a striking very short video of how mmWave performance can be destroyed simply by closing a door.
On the other hand, Swisscom/Fastweb on May 2 committed three billion euro to bring 26 GHz mmWave to 8 million Italian homes. They are sure they will deliver a gigabit 500 metres. Ted Rappaport of NYU, the leading researcher, emails me, "5G small cell operating on mmWave spectrum should reach 100 to 200 metres in a dense urban environment, up to 900 metres in suburban areas."
Whether mmWave reaches 200 metres or 800 metres is the biggest unknown in planning for 5G.
