Zhu Huimin indicates Huawei is moving to high volume production. I once suggested, "Don't believe any equipment claims until 10,000 are deployed." Most problems, including those from heavy use, will appear by then. By that test, Massive MIMO - at least the TDD variety - is now solid. The first announcements of Massive MIMO commercial use were just after a year ago. Softbank Japan was the pioneer; I broke the news that China Telecom was also buying thousands. Although Huawei does have a 32x32 antenna FDD Massive MIMO, her recommendation is to stick with 8x8 in FDD spectrum.
CEO Gavin Patterson of British Telecom, CTO Bruno Jacobfeurborn of Deutsche Telekom, and SVP Arnaud Vamparys of FT Orange all committed to deploying Massive MIMO. (I've added them to the map.) There is no doubt that TDD MM works and will rapidly deploy around the world. Two Huawei executive confirmed to me Massive MIMO is ready for Africa. The need is great; there are very few landlines so almost all the Internet connections are mobile.
African wireless sucks, with caps so low video watching is severely restricted. The orders haven't been announced, but Vodacom South Africa and Safaricom Kenya are both very interested. Ten African countries have per capita income similar to India, where all three carriers likely to survive now moving rapidly.
All are TDD; FDD is only in trials, with major problems likely to limit deployment. Zhu is very uncertain about FDD. A senior colleague agrees, not expecting many orders for FDD systems.
In 1999, DSL reached a similar threshold of 10,000 deployed. By two years later, growth reached hockey stick levels and today is ~400M lines.
Massive MIMO is ready for hockey stick growth.
