In the US, the last mile of internet infrastructure is an enormous problem. There are two reasons for this: technical restraints holding back the bandwidth needed to support modern-day internet traffic, and a lack of compe ion between the major carriers selling internet service to the end user.
Most of America's telecommunications infrastructure
relies on outdated technology, and it runs over the same copper cables invented by Alexander Graham Bell over 100 years ago. This copper infrastructure—made up of "twisted pair" and coaxial cables—was originally designed to carry telephone and video services. The internet
wasn't built to handle streaming video or audio.
When your streaming video reaches that troubled last mile of copper, those packets will slam on their brakes as they transition from fiber optic cables to copper coaxial cables. Copper can only carry so much bandwidth, far less than what the modern internet demands. Only fiber optic cables, thick twists of ultra-thin glass or plastic filaments that allow data to travel at the speed of light, can handle that bandwidth. They're also both easier to maintain and more secure than copper.
As consumers demand more bandwidth for things like streaming HD movies, carriers must augment their networks—upgrade hardware, lay more fiber, hire more engineers, etc.—to keep traffic moving freely between them. But that costs big money—like,
billions of dollars in some cases. Imagine the cost of swapping out the coaxial cables in every American home with fiber optic cables. It's thousands of dollars per mile
according to some government records.
And here's the kicker. The last mile infrastructure is controlled by an oligarchy—three big cable companies: Comcast, Time Warner Cable, and Verizon. You know this well. One in three Americans
only have one choice for broadband service; most of the others only have two internet providers to choose from.
Without compe ion, there's no incentive for internet providers to improve improve infrastructure. These massive telecom companies create a bottleneck in the last mile of service
by refusing to upgrade critical infrastructure. And they can charge exorbitant prices for the sub-par service while they're at it.
So your internet is ty and slow
and expensive.
