This is part of the big drive to deploy "5G" network technologies in 2020. Better spectrum efficiency means you can support more customers doing data-intensive tasks with fewer cells, that was a big drive behind LTE as well. With the bandwidth available to LTE connections already I think for the time being we're pretty much topped out on the bandwidth an individual terminal needs, just need to service more of them with less hardware.
