2.2 - will never happen. The same things restricting rural broadband speeds also prevent 5G coverage from replacing wired connections - namely, the revenue per mile of cable is garbage. For many places you’ll have to backhaul quite a lot of remote towers to actually cover a rural area properly, and in terms of cost it is either higher or indistinguishable from the cost of local broadband. Rural broadband is garbage because the ROI is garbage - the big players are largely coasting on investments made by the smaller players that went bankrupt because it was financially impossible. It only exists because the big guys bought it on the cheap.
