Here is a short article on the technical characteristics of G.fast, the "solution" that is supposedly going to allow the telephone companies to compete with the cable companies.
Don't want to click through and read it? Here is the short summary:
The article talks a lot about how great its working in Europe, but Europe is not the U.S. Cities are much denser generally in Europe, so more residences are going to be closer to the DSL switches. G.fast sounds good, but it does absolutely nothing for rural broadband, where distances from the DSL cabinet are measured in miles, not feet, and where the ancient copper cable plant can barely handle existing "little broadband" DSL, much less the very demanding G.fast. To get speeds of hundreds of megabits out of G.fast, you not only have to be close to the switch, the copper cable between your home and the switch has to be perfect, meaning brand new.
Hilariously, the article touts a test in Britain where they got 700 meg speed.....woohoo....wait for it....with a wopping 57 feet between the switch and the user. Fifty-seven feet.
That's all you have to remember about G.fast: 57 feet.
