What about all the neighborhoods without poles, where power and phone services are all underground ?
We can always tell when AT&T is working on their new system somewhere in our neighborhood because all our internet service goes down, reportedly from a cut cable. We have no poles anywhere and all cables go through an easement area on the back of the property.
I imagine they will be able to use rooftops, and install towers. Much like they do today for cellular signal delivery, many of which are camoflaged to look like trees.
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.
