For whom? Currently ADSL companies advertise Internet access in my area slightly more expensive than Ethenet providers for the same download speed (and much slower upload speed). In order to offer ethernet, you have to have cables capable of carrying it. There are a lot of buildings and neighbourhoods that have lots of phone cable but no cat5 or fibre. What's the problem with stretching such cables? Currently at least 3 providers have their separate ethernet networks in my building.
You are repeatedly missing a *very* important point - you are talking *about where YOU are*. Ethernet cabling in existing facilities is extremely rare. There is a *HUGE* cost in just labor and materials to deploying such a network. Obviously where you are _somehow_ those organizations are defraying that cost [subsidies, tax breaks, grants, etc...]. I have some experience with issues regarding transportation, and network infrastructure suffers from one of the same major issues: *RIGHT-OF-WAY* If you want to put a wire on a pole, under a road, under a rail line, etc... you have to have RIGHT-OF-WAY from whatever authority controls that impediment. That means you need *LAWYERS* to build your network. Which may end up costing more than the physical infrastructure.
The only way is via ADSL riding on the phone lines or by the cable TV networks. Why do you think cable TV coaxial(or anything) is better than UTP?
Nobody is saying it is. But it _is_ there, pretty universally. Cat-5 and fiber are nowhere near universal.
To have cable TV you also have to make wiring.
But the wire was installed 20 years ago. Cat-5 didn't exist.
In this country television is historically by radio shared between flats by coaxial. Even if there were (or are) some cables connecting the buildings to a district TV hub (there were sometime in 90s translations from a district TV studio), it is unevident by whom such cables may be owned and why they should be interested in Internet deal and even if they agree how all customers would share one cable?
They are interesting for providing Internet because they are already there. There are no RIGHT-OF-WAY issues. I just replace what is on both ends of the wire and BAM - I have a network.
Only imagine: plain UTP ethernet cable has bandwidth 10-100 times greater than any old wiring that could exist, even without optics and cat5 cables. If you want to provide modern cable TV with Internet, you still have to provide optics to any building, so no difference from ethernet.
No, you can provide a large amount of service on existing cable with a negligible installation cost; you just replace what is on both ends of the wire.
It cost a lot to rewire an area with a new cable type. Which area do you mean? One building? Or a wider area?
City blocks, neighborhoods, industrial parks, etc... where you have to cross roads, rail lines, rivers, and all manner of impediments you don't own.
So, the work around, in the mean time, is ADSL, cable, microwave or satellite.
