The problem is always between distances and speed. We need to find a technology where speed won't be affected by distances but this is hard to find since we are limited to the materials already installed. Wipe all these copper cables and turn it into optical fiber. We could pass everything through the fiber - radio, tv, internet, phone... without affecting the speed/distance
And currently fiber is the only medium we have that doesn't have a (major) speed over distance issue. With cable internet the number of connections between you and the hub changes speeds and with DSL pure distance changes the speeds.
But a fiber installation is extremely expensive. To install a fiber connection in my area to one building where the fiber is already at the street level costs almost $2000. To run fiber under one city street costs over $10,000. Upgrading and replacing all phone and cable lines with fiber for even one city costs millions of dollars. Now expand that to the entire infrastructure across a state, now the country, now the world.
Good luck.
It's a lofty goal, but not one likely to be achieved in our lifetimes. On top of simple costs you run into legal and political problems trying to do a project of that nature. Depending on the right of way clauses written into property titles, some specify exactly what may be done with the right of way easement. Others do not. It takes a team of lawyers to figure out the answers to just that one question but it must be answered for every property your line passes through. If the title specifies certain things but not fiber optic cabling then you're stuck, you need to take the people to court to get it added or permission to pass the cabling through their land. Now add to it cities and counties that have passed their own laws and restrictions on cabling, right of ways, infrastructure upgrades of any kind, etc, etc.
This is the exact problem the company I work for now is in. We want a direct fiber link from point a to point b. The city where point a is has a contract with another company to provide the fiber optic connections in and out of the city. On top of that the land we want to run the fiber through is county land and they will not provide a permit to add fiber optic cables in that area. So currently point a runs entirely on one fiber link and every time it gets cut the entire city loses all phone, internet, even cell service. But we can't get in there to provide our own backup fiber link, so everyone is stuck.
