Economy Worries Slowing DOCSIS 3.0 Rollouts > Faster

Re: Faster

You'll understand what how much data of x Mbps per channel is? it is 30 Mbps per channel over coaxial cable and let's math that 70 channels are bounded that take total is 2100 Mbps of data downstream.

64K TCP WIN is officially dead for long high latency fat network connection across internet.

What you fail to understand is that cable ISPs will not give up 70 channels worth of bandwidth for internet. They do not even want to give up 8 channels worth to get to the currently defined upper level D3 spec(4 channel D3 is all that is currently being used rather than 8 channel). Every channel they add to internet is a channel they take away from TV. So it is HIGHLY unlikely that we will ever see 70 channel(at least as channels are defined today).

The other point is that there are no "killer" applications that will not currently work at 20 meg (much less 300 meg), so there is not much residential call for 1 gigabit. You will not be able to tell the difference (using email or web surfing) between 20 meg and 1 gig. They are already putting caps on systems, so it will not be all that useful in downloading large files either (20 secs to get to your cap).

No, You fail to understand that cable internet does not interfere with TV shows that is very simple and cable operators can give more channels as new speeds hit on market so you will never know when cable will hit new speeds marketing. Ultra wideband is future of next generation and that D3 is too slow to me. You need to understand that both TV cable and cable modem uses video encoding so again there is no interfere video channels.

Digital TV (qam) uses bandwidth just like cable internet. Just look at the link I provided earilier to the docsis wiki. What is being transmitted on those channels is irrelevant. A used/full channel is a used/full channel regardless if it is being used for TV or internet. A channel can be used for internet or it can be used for TV but it cannot simultaneously be used for both. When I speak of channels I am speaking of mhz not like channel 13 (which is just a label for a certain defined mhz).

You should research on how we can use same one each channel of 6 Mhz so we can watch TV on same channel and using internet on same channel as we can use both in this a way that we see there is no interfere of channel that really uses same video encoding if even we watching on analog TV and cable modem on same channel that shouldn't be issue so again there is no interfere, You should considering with cable operator so they will tell you and explain to you how cable channel works.

That is incorrect, Lazlow is correct. Break up your sentence into multiple sentences. It looks like you are using some kind of cheap online translator.
