Re: And what is 5G?
Well the objective can't be speed, as that can already be achieved with LTE. LTE also allows for low processing power nodes for applications like IoT, or for new modulation schemes to be added, or beam forming, or macro-diversity and the like. That's why it's called Long Term Evolution.
5G is so far, mostly about redefining every protocol to be tunneled though HTTP without actually having any new desirable features.
