No, because 5g is a shared medium. It can deliver... 3 gigabit/s? or something like that? Let's say it's 10Gb. That's 10gb shared with everyone in the vicinity, which is not great especially in high density areas like apartment buildings.
Furthermore, you still need to run fiber to the actual base stations anyway.
Personally I am yes, but I know that's not the case everywhere. I get that you mean in terms of ROI, but that's ROI for the business, not for you the customer. So I guess what I'm getting at is, why would you suggest the thing that's better for the business but worse for you?
Because it’s not worse for me, it’s the same cost and value. To the other point, companies outside monopolies and prestige add a margin, if they do it cheaper it flows to the consumer, a company isn’t going to have low fiber margin if they can have better 5g margin, but I suppose the proof is in the pudding (and government incentives)
