It doesn't enable operators to install a large number of micro-cells, it requires it. And this is where I think 5G may end up being disappointing. I think telcos will encounter increased resistance to putting up millions of microcells, and the cost will end up being way higher than they anticipate. So coverage in the mm bands will end up being extremely spotty (way worse than 4G now), and may end up being a near-bust. That's my .02 anyway. But I live in a suburban-ish place where 4G coverage is mostly a cruel joke, despite being just across the Golden Gate Bridge from 4G-ground-zero SF.
