ATT has fiber they are working on 5G they have been around forever and are pretty much nationwide. The cons are that they are losing video customers most likely landline customers and they are unionized oh yeah and they have horrible billing practices and suffer from corporate red tape. If they could buy Time Warner and maybe gobble up some cable companies they would be supremely positioned. My first experience with solar was from a Bell Labs kit. I have a limit order to buy some more!
