Comment What's the max bandwidth of coax cable? (Score 2) 341
And in most areas, how "full" is the coax line between my house and the fiber node? Ie, how much of the usable coax bandwidth has been allocated to cable channels, on-demand viewing, phone service, alarm monitoring, and Internet access?
Has switching from NTSC analog to all those HD channels (even though they are compressed, etc) been a net gain in usable bandwidth on the coax or just a wash?
I always just wonder if Comcast isn't just trying to keep that coax cable capable of handing TV and Internet by various means of suppressing bandwidth consumption on Internet usage.
The suck for Comcast is when that coax cable "runs out" of bandwidth and there's no room to cram yet another HD sports channel on. A project to migrate from coax to fiber would be a total nightmare for them.
I'm not trying to defend or justify anything they do, I'm sure it's at least half oriented towards nickle and diming and profiting off of manufactured scarcity but coax cable shared by many dwellings seems like a major bottleneck that will eventually have to be addressed and it will not be cheap.
