That is where their “Gigapower” project comes in... they are starting in areas where they have what’s called “fiddle fiber” which is a hybrid fiber/copper and is being done first because most of the infrastructure (equipment) is already in place to run fiber. Once those overbuilds are done, they’ll start on replacing the copper in the older neighborhoods.
How does that solve the problem of not having any poles to get an elevated position for wireless gigabit ?
The article is not about providing fiber into the homes, it is about putting wifi hotspots on top of existing power or telephone poles with no wired connection into the homes. That is where the savings in infrastructure rollout come from, by not having to dig up streets to run fiber into homes.
A mesh network of hotspots on poles a few hundred feet apart through a neighborhood could provide a gigabit wifi coverage at a relatively low cost compared to fiber installation. But what about the suburban and rural neighborhoods with no poles for anything ?
