#2The future are super dense networks Lifi, 60GHz, then 5Ghz, then 2.4-1.8GHz because that will give the most bandwidth for the buck. You always want higher frequency first because it can carry more and then fall back to lower frequencies if you are out of coverage of the high freq.
Outside developed areas there will be internet by solar drones and lower orbit satellite internet.

#4In the mean time, I am stuck at slow 3G. Are there regulations for the frequencies at which they can transmit their services? Err?

LiFi is such a sketchy idea to me, due to how IrDA has been in the past.
Maybe somehow I'm the last generation who remembers really shitty remote controls for televisions. :\

The bandwidth doesn't depend on the frequency you're occupying, but on the amount of spectrum available: you "usually" get in the order of 1 bps for every Hz of spectrum available for mobile: a 20Mz chunk of spectrum will give you ~20Mbps, no matter if it is 700MHz or 5 GHz. (Please notice that YMMV, LTE gets several times that, illustrative, bla bla bla, etc.).
Higher frequencies have awful penetration and range, that's why today you define who wins in the mobile game by the amount of 700MHz and 800MHz spectrum they own. In other words, lower frequency spectrum is (within certain limits) always better.

#7Is 5G even an accepted standard yet?

That may be true at present, but higher frequency systems do ideally allow for higher data rates.
EDIT: No, I'm wrong.

#9Honest statement: people in big orgs string together stuff in mad lib format to get headlines. Speaking from personal experience, this is the way academics works. From what I can tell there is a disproportionate amount of this amongst the more stately corporations, IBM et al. too. I say this to advise consideration about how much impact will come of such "impressive" projects.

That's simply false. What is true is that per-band allocations tend to be larger at higher passband frequencies, but the width of the baseband in absolute terms is what determines information capacity. See: The Shannon limit
