In cabling parlance installers talk about the last mile being the last mile of cable that needs to be installed for the end-user to receive whatever service they are providing.
Recently Comcast entered into my neighborhood. They've been tunneling dredging cabling and tearing up our local neighborhood. I can't wait for Comcast to enter into service because they are clearly a more superior product to the current supplier.
As they are doing this installation I find myself wondering why they aren't applying a Wi-Fi product or some sort of mesh whereby they would not have to enter or dig as much as they are. There are clearly challenges associated with a Wi-Fi scenario in that there is a single point of failure that effect multiple customers.
