What's the problem with stretching such cables? Currently at least 3 providers have their separate ethernet networks in my building.
Cost. In an existing building you have to run cables in conduits that barely have room for phone cables or run new conduits on the outside of the buildings. Laying new cables around town is also expensive.
Why do you think cable TV coaxial(or anything) is better than UTP? To have cable TV you also have to make wiring. UTP has a maximum usable distance of 100M. This means you'll need lots of repeaters for lots of cables to deliver ethernet. Cable TV plant has been around for many years and the technology used works better over the greater distances.
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.
I think you have that reversed. Cable TV plant handles much greater bandwidth than UTP and does it over much greater distances. On my shelf beside me there's a cable modem that is capable of up to 30 MB/s. Many of my neighbours have similar. These are all supplied by the same cable that's also carrying hundreds of digital TV channels, including several HD. It still carries analog TV too. All this on one single cable serving over 300 homes. A UTP cable couldn't even reach the street from my condo and still provide usable ethernet.
Which area do you mean? One building? Or a wider area?
Both. Either a building or a neighbourhood. Retrofitting cable into a multi-unit building is a big, expensive job. Laying new cable down the street is also expensive. Cables like that are amortized over decades. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
