High-speed networks through 5G may represent the next generation of cord cutting. Rural connectivity is a persistent problem; many rural users (and some urban users) are still limited to dial-up speeds. There are impressive estimates for latency for 5G, but reality has a tendency to be harsh on such predictions. I don’t, do you?
