Massive MIMO is the next great step in mobile networks. Huang Yuhong of China Mobile and Hidebumi Kitahara of SoftBank are deploying hundreds of nodes and reporting performance improvements of 2X to 10X. Sprint in the U.S. and 3 in Austria are firmly committed. Gig LTE - 4x4 MIMO, 3/4 band aggregation, and 256 QAM is spreading rapidly in 2017; the next step will be the 64+ antennas and beamforming of Massive MIMO, some at millimeter wave. I had a chance to ask some experts a few questions so put together these. Others welcome.
in 2018-2019, what's a smart Massive MIMO deployment strategy for a network with growing traffic?
