Re: [OOL] What speed tier increases would you like to see?

said by kickass69:

Eventually Cablevision will have to go FTTH to keep up with new applications that require more bandwidth now and in the future.

Cable companies still have a long while till that is needed. Docsis 3.1 will allow 10gigabit/10gigabit. Add in things like switching to all ip and you will see that cable companies have a long way till they have to go to ftth.

10 gig a node (if a node is 250 houses) all 40/40 connections . if you split that node that would allow 75/75 connections to every home .

Verizon stopped there ftth because of fewer subscribers then they that. google fiber is only 1 area of the country.

You can't do the upload without a major rebuild since the return is currently way to small... Every single amp and splitter in the plant and customer homes would need to be replaced... Before doing that you may as well look at FTTH - for arial the investment level won't be much different...

Replacing amps and splitters is still WAY cheaper then rewiring every pole and every house and adding onts to every house.

also docsis 3.1 is adding things like ofdm and doing away with those 6 and 8mhz channels.

I do not see why splitters and amps have to be replaced if they are not using anything aabove 850mhz

Verizon stated it costs them 3k to wire each house for fios. Times that by 3 million customers and that's a HUGE price tag. Not including replacing the miles of fiber. Cable can replace amps and splitters as people order the new tiers that dcosis 3.1 enables.

To get 10gbit on the return the frequency ranges need to shift - e.g. the return needs to be much wider than today....
I don't disagree on the 'cheaper' aspect... The 'much cheaper' holds true until you take into account bandwidth requirements for 3D HD channels etc... at that point you'll likely need to bring the plant form 850mhz to 2ghz - and need to replace coax as well...

Are you taking into account changing over to all ip and mpeg 4?
