US 5G deployment will leverage spectrum above 24 GHz where it is feasible: https://arstechnica.com/information-technology/2015/10/5g-mo.... The FCC is working on auctions of 100+ MHz channels in these bands: http://www.telecompetitor.com/fcc-proposes-schedule-for-28-g.... AT&T already spent more than a billion dollars buying up that spectrum. It’s starting 5G trials at 15 GHz: http://www.lightreading.com/mobile/5g/atandt-5g-trials-to-st...

In the US, almost all LTE deployment is below 2 GHz.

24GHz will require line of sight. I can't see how this is going to work for anything more than cell backhaul or fixed wireless access in very rural areas (without trees)?

At relatively short distances (hundreds of meters), enough radio waves bounce around in the environment to still make it to the receiever. https://spectrum.ieee.org/telecom/wireless/smart-antennas-co.... You need beam forming antennas to take advantage of this fact.
