said by rradina:As somebody pointed out above they are working on making it all IP. Look up ccap.
They are changing the modulation standard (PHY). Calling it 3.1 seems like it's just a firmware upgrade when this is a significant change.
Aside from the name, if it's cheaper to replace modems and head units vs. pushing fiber all the way to the customer, why wouldn't cable do this?
What isn't clear is how much spectrum is used for the max speed. Is there room for multiple on the same coax run or does the max speed require all of it? If not, how many on a single coax run and how much room is left for QAM video?
If it's possible to design a couple per node + keep the existing QAM video, cable could gradually evolve into a pure IP data and video solution. Most new TV's support IP video streams, as do desktops, laptops, tablets and even smart phones. Could it happen? Boy, I sure hope so. Of course content providers would have to be convinced of this being sufficiently secure.
