"We are planning commercial deployment of Massive MIMO sometime in 2017 (we cannot communicate definite dates yet)." Tom Tesch, Hutchison Drei Austria. Three years ago, Stanford Professor Paulraj told me Massive MIMO was going to produce an enormous capacity boost. It's now coming out of the labs. Every network architect in the world is watching the Massive MIMO at Softbank in Japan and China Mobile. They are getting between 3X and 10X more capacity in the same amount of spectrum and are ordering thousands of systems. I've received so many reports of "tests" I ignore them. I'm now getting committed builds, including Sprint in the U.S.
The press release said "tests" but company spokesman Tesch confirmed to me the decision is made to deploy.
