Part 1 explains who originated massive MIMO and how it works IEEE Fellow Thomas Marzetta is well known for originating the 5G massive MIMO (multiple-input multiple-output) technology in 2006, which telecom experts consider to be one of the cornerstones of 5G wireless communications. This technology uses many small, individually controlled, low-power antennas to directly beam…
