In many suburban developments, the power/communication lines are all buried underground. It would probably be much easier to install a couple of microcells around the neighborhood than to dig up everyone's lawn.
I was lucky enough to live in a neighborhood where Verizon initially installed FiOS. It was a massive undertaking. They had to trench every street in my development. I was young at the time, but I remember thinking how massive the effort was considering not every house would even sign up for it.
They ran aerial fiber to the neighborhood, and then ran the fiber under each street, with the final run being placed in the backyard easement between house rows (with a Ditch Witch doing the heavy lifting).
Family member is going from AT&T DSL for $40/month with 3Mb down/1Mb up to $50/month for 200Mb down/75Mb up (with a two year price guarantee and no data caps). It’s quite the deal.
At no point does a fiber installation require digging up an entire road or even your lawn.
Disclaimer: I have contributed to a muni fiber project, and am familiar with trenching/arial mounting and premises termination costs.
