If there’s fiber to every curb, then why bother with a separate 5G standard for stationary usage? My T-Mobile phone already incorporates WiFi for VoIP (although SMS is flakey), and has for years and transitions seamlessly (more or less) between the two. Leave the carriers to provide mobile Internet access via WiFi in public spaces and over private networks (as they do for voice, today), and via improved implementations of existing long-distance wireless technologies. If there’s fiber to the curb of my house, I’m sure that somehow, I’ll be able to pay someone a reasonable fee to hook up to it and use it.
