That must mean something different than I was thinking.  Like 64 time slices 
for different traffic, or dividing the 360 degrees into 64 antenna beams.

Sprint\T-Mo has done 64x64.

I still can’t wrap my head around how they get ∞x∞ MIMO and 1.21 gigawattsbits 
from 5 MHz of spectrum.  I understand MU-MIMO and beamsteering and all that, 
but when they start tossing around stuff like 8x8 MIMO I don’t see how you get 
that many orthogonal signals on the same frequency.

 

But for maximum spectral efficiency, I assume they use more than 1 
polarization, whether V&H or +45 & -45.

I have a passive antenna experiment in the works.  Rather than guess at the 
right slant, I think I will try V pol initially.

When GSM began they started using vertical polarization. But as the need for 
capacity arose antennas changed to slant 45 X polarization.
